Georgia Population Characteristics
Georgia, the largest state east of the Mississippi River, is a predominantly rural state, yet the
majority of the state's population is concentrated in the counties surrounding the metropolitan
Atlanta area. (Figure 1.1) Consequently, the majority of the state's health care resources,
including viral hepatitis testing, care, and treatment resources, are located in the metro Atlanta area. This poses great challenges in reaching and providing
Figure 1.1: Population Size by County, Ge orgia, 2016
services for those in other areas of the state who are
at high risk for and chronically infected with HBV and
HCV.
The estimated population of Georgia in 2016 was 10,310,371, comprising 3.2% of the US population. The population of Georgia has continued to grow, with a 6.4% increase since 2010, compared to a 4.7% increase nationally.1 Georgia's Office of Planning and Budget projected Georgia to experience the fastestpaced population growth (21%) from 2010-2020 in the southeastern United States, followed by North

Carolina (18%), Florida (13%), South Carolina (10%), Tennessee (10%), and Alabama (8.5%).2 The vast majority of population increases from 2010 to 2016 occurred in the metro Atlanta area, north Georgia, and parts of southeast Georgia. Many rural counties throughout the state have experienced decreases in population. (Figure 1.2)

The distribution of gender and age in Georgia is similar to the national population. Males and females were almost equally proportioned in 2015, with females making up 51% of the population in both Georgia and the US.3 The majority of Georgia's adult population is between 20 and 64 years of age, with a fairly even distribution between males and females in the various age groups. Approximately 28% of Georgia's population is 19 years of age or younger. Those over the age of 65 years make up approximately 12% of Georgia's population, with slightly more females (7%) in that age group than males (5%). (Figure 1.3) Comparing the median age of Georgia's population at 34.3 years in 2005 to 35.9 years in 2015 shows that Georgia's population is aging overall.4

In 2015, 11.1% of Georgia's population was uninsured, increasing to 12.9% in 2016.6 Based on 2015 Census data, 20% of Georgians between the ages of 18 and 64 years were uninsured, 12% had government health insurance, and 68% had private health insurance. Of those under the age of 18 years, 7% were uninsured, 43% had government health insurance and 50% had private health insurance coverage. For those over the age of 65 years, 66% had government health insurance, while 34% had private coverage and 15% were uninsured. (Figure 1.7) The majority of the uninsured population less than 65 years of age were concentrated in the southern and eastern areas of Georgia as well as parts of north Georgia, which are largely rural areas of the state.

Hepatitis A
Hepatitis A virus (HAV) causes acute liver disease, is infectious, and can be prevented by vaccination. HAV is shed in the feces of an infected person and can be transmitted when an unprotected person consumes contaminated food or water or has close contact with an infected person. Most young children under 6 years of age do not have symptoms with HAV infection whereas, more than 70% of older children and adults are likely to have symptoms that include jaundice. Recovery from HAV provides life-long immunity. Although this virus does not result in chronic infection, acute infection in persons with compromised immune systems can be serious.7
In 2015, a total of 1,390 cases of hepatitis A infection were reported in the US, a 12.2% increase from the number of reported cases in 2014. However, the incidence rate remained the same from 2014 to 2015 at 0.4 per 100,000 population.7 In Georgia, new HAV infections (acute cases) have declined from a previous high of more than 900 cases reported in 2001 (11.1/100,000 population) to an annual average of only 34 cases between 2012 and 2016 (Figure 2.1), with the 2016 rate matching the 20142015 national rate (0.4 per 100,000 population). This remarkable decrease in

HAV infections can be attributed to the availability of hepatitis A vaccine and the May 2006 national recommendations to immunize children.8 Georgia took a tiered approach by requiring universal hepatitis A vaccination of children born on or after January 1, 2006 who were entering daycare, beginning in 2007; in 2011, it was required for daycare, kindergarten and 6th grade entry. Over the past five years, HAV infections in children ages 1 to 17 years were rare in Georgia, comprising only 8% of reported cases; most HAV cases occurred in adults (median age 42 years). (Figure 2.2) While recent case numbers have been low, and many cases had undetermined

Hepatitis B
Hepatitis B virus (HBV) causes acute liver disease that can be transmitted through exposure to blood or body fluids (semen, vaginal fluid). Common exposure risks for HBV include unprotected sexual contact; sharing needles, syringes, or other drug-injection equipment; or during birth from an infected mother to baby. As a bloodborne pathogen, HBV is transmitted via direct blood-to-blood exposure or sexual contact. Symptoms of acute HBV infection can include nausea, vomiting, abdominal pain, fatigue, dark urine, and/or jaundice. Hepatitis B infection in pregnant women is of particular concern, due to the potential for transmission to their newborns who are at risk of perinatal HBV infection. For most adults, HBV infection can resolve in three to six months after exposure, leaving the recovered person immune to HBV; however, HBV can progress to a life-long chronic infection, leaving a person infectious to others and at increased risk for developing cirrhosis and/or primary hepatocellular carcinoma (liver cancer), and leading to end-stage liver disease. According to CDC, there were an estimated 20,900 new HBV infections reported in the U.S. in 2016, with about one-half of chronic HBV infections occurring in Asian/Pacific Islanders.9 In Georgia, there were 1,875 confirmed HBV infections (acute and chronic) reported in 2016, with 35% occurring among Asian/Pacific Islanders (Table 3.1). Georgia has a large immigrant and refugee population, mainly from Asian and African countries. Georgia's HBV surveillance data show that when country of birth was reported, a large percentage of chronic hepatitis B infections were diagnosed in persons who were foreign-born, and most acute cases occurred in U.S.-born persons. Of 51% of chronic HBV infections reporting country of birth in 2016, 44% were born outside of the U.S. In contrast, of the 26% of acute cases reporting country of birth, only 5% were foreign born. Table 3.1 also compares acute and chronic HBV case counts and percentages by race. While most newly-reported chronic HBV infections in Georgia in 2016 occurred were in Asian and Black or African American populations (34% each), only 14% were White. As Georgia's population by race in 2016 was 61% White and 32% Black or African American10, acute HBV cases occurred disproportionately among White (51%) and Black or African American (36%) populations; Asians and Hispanics had the lowest rates (1% and 3%, respectively) of acute HBV infections

Georgia's acute HBV case counts have fallen from more than 200 cases in 2005 to 99 cases in 2016 (Figure 3.1); however, during the years 2012-2016, acute HBV infections among adults in Georgia increased.
Figure 3.1: Confirmed Acute HBV Infections, Georgia, 2005-2016
Acute HBV infections in persons <18 years of age have not been reported in Georgia since 2013. (Figure 3.2) This can be attributed to Georgia's school immunization

law requiring hepatitis B vaccinations in children born on or after January 1, 1992, for daycare and school entry. By 2016, the oldest students affected by this requirement had reached 24 years of age. As shown in Figure 3.2, there was a dramatic drop in acute HBV infections in the age group 1930 years in 2016. These
infections occurred primarily in those ages 27-30 years of age. The majority of acute HBV cases occurred among unvaccinated adults in the age group 31-40 years (40%). Note that there were no reported cases of acute HBV infection in those between 14-18 years of age during between 2012 and 2016.
In contrast to acute HBV infections in Georgia, the number of chronic HBV infections reported by age group (Figure 3.3) remained fairly stable from

Of the acute HBV cases for which risk factors were documented (Figure 3.7) during 2012-2016,, 19% were attributed to having multiple sex partners in the six months prior to symptom onset; 11% had contact with a known hepatitis B case within the past 6 months; 11% reported ever injecting drugs; and 8% reported injection drug use in the six months prior to symptom onset.

Number of Reported Cases
Historically in Georgia, acute HBV infections are reported in greater numbers in the more densely populated metropolitan Atlanta counties. The map of 2016 cases in Figure 3.8 shows this to be true; however, it is also apparent that acute HBV infections cases were also documented in North, Central, and Southeast Georgia in more sparsely populated rural regions of the state. These geographic areas of Georgia overlap with locations where increasing hepatitis C infections in young adults have been

were distributed statewide, with the most notable density in the metro Atlanta area, where large populations of immigrants and refugees reside.
A continuing barrier to healthcare access in Georgia, as well as other states, is the lack of providers available that offer hepatitis B care and treatment, especially in rural areas of the state. The map in Figure 3.10 shows that the majority of HBV patients reside and where the location of healthcare providers are primarily in the metro-Atlanta area. This distribution demonstrates the obvious need for medical providers to manage the care and treatment of HBV-infected persons living outside of the metro Atlanta area, especially in Central and South Georgia.

Perinatal Hepatitis B
HBV can be vertically transmitted from an infected mother to her newborn at birth by parenteral or mucosal exposure. Transmission can occur from blood exposure through microscopic tears and abrasions during labor and delivery. Intra-uterine infections can occur through threatened abortion, but are rare and account for less than 2% of infections11. Breastfeeding is not a mode of transmission and is not contraindicated for HBV-infected mothers. As many as 90% of infant HBV infections will progress to chronic infection, placing the child at risk for developing liver cancer or dying prematurely12.
The goals of Georgia DPH's Perinatal Hepatitis B Prevention Program (PHBPP) are to identify all pregnant women who are infected with HBV by monitoring reported hepatitis B surface antigen (HBsAg)-positive test results, and to ensure their infants receive and complete timely postexposure prophylaxis (PEP), complete hepatitis B (HepB) vaccination and postvaccination serologic testing (PVST). CDC estimates that 18,945-26,444 births will occur to HBsAg-positive women each year in the U.S., with 544 to 865 of those births occurring in Georgia.
Transmission Perinatal HBV transmission from mother to infant at birth is very efficient. If the mother is positive for both HBsAg and hepatitis B "e" antigen (HBeAg), 70%90% of infants will become infected by age 6 months in the absence of PEP with HBIG and HepB vaccine. The risk of perinatal transmission is about 10% if the mother is positive for HBsAg only.
Children who are not infected at birth remain at risk from long-term interpersonal contact with their infected mothers. In one study, 38% of infants who were born to HBsAg-positive mothers and who were not infected perinatally became infected by age 4 years11. HBV can survive outside the body at least 7 days. During that time, the virus can cause infection if it enters the body of a person who is not infected. Sharing items such as toothbrushes and nail clippers with an infected person should be avoided. According to CDC, there have been instances in which HBV has been spread to infants when they received food pre-chewed by an infected person. This practice should be avoided.
Postexposure Prophylaxis (PEP) Infants born to HBsAg-positive mothers must receive PEP to help prevent HBV transmission. PEP with HBIG and HepB vaccine administered 1224 hours after birth, followed by completion of a 3-dose HepB vaccine series, has been demonstrated to be 85%95% effective in preventing acute and chronic HBV infection in infants born to women who are positive for both HBsAg and HBeAg11. HBIG provides passively acquired anti-HBs and temporary protection (i.e., for 36 months) when administered in standard doses11. Studies are limited on the maximum interval
13 | P a g e
GEORGIA VIRAL HEPATITIS EPIDEMIOLOGIC PROFILE
after exposure during which PEP is effective, but the interval is unlikely to exceed 7 days for perinatal exposures.
In birth cohorts 2013-2015, 940 (98.5%) of 954 HBV-exposed infants received PEP with HBIG and HepB within 7 days of birth. Of the 14 infants that failed to receive PEP, 4 infants were successfully recalled for HBIG administration within 7 days of birth.
HBV in Pregnancy The American Congress of Obstetrics and Gynecologists (ACOG) endorses CDC's universal screening recommendation that prenatal care providers should test every woman for HBsAg during an early prenatal visit (e.g., in the first trimester), even if a woman has been p reviously vaccinated or tested. The presence of a confirmed HBsAg result is indicative of ongoing HBV infection. All HBsAg-positive persons should be considered infectious11. All Georgia physicians, laboratories and other healthcare providers are required by law (O.C.G.A 31-12-2) to report HBsAg-positive pregnant women to DPH within 7 days of laboratory confirmation. Failure to report these women to DPH places the woman and her newborn at risk of missing critical interventions to prevent disease transmission.
Antiviral Treatment All HBsAg-positive persons are infectious, but those who are also HBeAg-positive are more infectious because their blood contains higher titers of HBV, typically 107 109 virions/mL11. The American Association for the Study of Liver Diseases (AASLD) recommends that pregnant women with viral loads above 200,000 IU/mL receive antiviral treatment to reduce the risk of perinatal transmission13. Several studies have found that immunoprophylaxis failure occurs primarily among infants born to women with HBeAg-positivity and HBV DNA levels above 200,000 IU/mL13.
In April 2016, the Georgia PHBPP began collecting antiviral treatment data, HBeAg status, and HBV DNA status for women with an Estimated Date of Confinement (EDC) or delivery date between April 1, 2016 and March 31, 2017. Among 361 tracked cases, 27 women were known to be HBeAg-positive. Eleven of the 27 (41%) were prescribed antiviral treatment. Among all 361 tracked cases, 10 women had reported HBV DNA levels greater than 200,000 IU/mL. Seven (70%) of the 10 were prescribed antiviral treatment; all 10 were also HBeAg-positive (Table 4.1).

Burden of Disease
HBV-Exposed Births The Georgia PHBPP identified 954 (0.24%) live births to HBsAg-positive women during 20132015 (Figure 4.1; detailed data can be found in Appendix Table 4.2). CDC estimates that 544 to 865 infants are born to HBsAg-positive women in Georgia each year. Unfortunately, less than half of these infants are identified by the Georgia PHBPP and receive case management services. This leaves the other half at risk to potentially fail to receive critical interventions that could prevent disease transmission. Medical care providers and laboratories that fail to report cases to DPH contribute to the case

identification gap. Even with reporting challenges, Georgia has increased the number of HBsAgpositive pregnant women identified annually through capture/recapture methods and other enhanced surveillance mechanisms.
HBsAg-Positive Mother Demographics
Age at Delivery In birth cohorts 2013-2015, 302 (32%) births occurred in HBsAg-positive women 30-34 years of age at the time of delivery (Figure 4.2; detailed data can be found in Appendix Table 4.3). Additionally, 297 (31%) births occurred in women classified with advanced maternal age (35 years of age and older). The youngest reported age at delivery was 18 years, with the median age at delivery being 32 years. The oldest reported age at delivery was 50 years.

Asian women accounted for 436 (46%) of
all HBV-exposed births in years 2013-
2015 (Figure 4.3; detailed data can be
found in Appendix Table 4.4). Black or
African American women were the
second largest racial group for HBV-
exposed births with 389 (41%) births
during the 3-year period. White women
accounted for 86 (9%) of the births and
Hawaiian/Pacific Islanders and Multiracial women attributed to less than <1% of births. A total
of 32 births did not have the mother's race available and were listed as "other" or "unknown."
Ethnicity Only 34 (4%) of the documented 954 HBsAg-positive women who gave birth reported their ethnicity as Hispanic. We were unable to identify the ethnicity of 22 women who delivered in the 2013-2015 birth cohort. (Appendix Table 4.5)

Country of Birth In birth cohorts 2013-2015 in Georgia, 737 (77%) HBsAgpositive mothers reported their birth country to be other than the United States, with 76 different countries documented. These foreign-born women likely acquired HBV at birth or in early childhood through contact with an infected mother or close household contact while living in a HBV-endemic area. The largest percentage of births occurred to HBsAg-positive women who reported being born in Asia and Africa where HBV is endemic. (Appendix Table 4.6 and 4.7)
Additionally, 216 (23%) of these mothers reported being born in the United States; 21 (2%) did not identify a country of birth. Of the women reporting the United States as their country of birth, numbers were highest among black or African American women (134 / 62%), white women (44 / 20%) and Asian women (28 / 13%).
HBV is endemic in all countries of Africa and the majority of South Asia11. In Georgia, 233 (24%) of HBsAg-positive births occurred in women born in Africa and 401 (42%) occurred in women born in South and Southeast Asia.
Insurance Status
Insurance coverage was reported by 812 (85%) of the HBsAg-positive women who delivered in
2013-2015 (Figure 4.4; detailed data can be found in Appendix Table 4.8). Medicaid was the
largest source of reported coverage
Figure 4.4: HBV-Exposed Births by Mother's Insurance Status at Delivery, Georgia, 2013-2015
and accounted for 447 (47%) of the insurance types. Private insurance
accounted for 352 (37%) and military
coverage was the reported type for
only 13 (1%) of the women. Uninsured
women comprised 97 (10%) of those
women who delivered during this
timeframe. We were unable to
determine the type of insurance
coverage for 45 (5%) of the HBsAg-
positive mothers.

The mother's insurance coverage type may be an indicator of other assistance services her newborn and family may need. Uninsured and underinsured infants are eligible to receive HepB vaccine at low cost or no-cost through the federal Vaccines for Children (VFC) Program and qualify for other services offered through DPH. Geographic Distribution The Georgia PHBPP identified 954 live births to HBsAg-positive women in years 20132015. Figure 4.5 shows the number of HBV-exposed births that were identified in 2013-2015 by their county of residence. The locations of Georgia's 81 delivery facilities are plotted on the map. Georgia has 79 delivery hospitals and 2 birthing centers. The majority of births occurred in 12 of the 29 counties within the Atlanta Metropolitan Statistical Area (MSA): Gwinnett County 230 (24.1%), DeKalb 180 (18.9%), Cobb 82 (8.6%), Fulton 88 (9.2%), Clayton 54 (5.7%), Forsyth 17 (1.8%), Henry 17 (1.8%), Douglas 14 (1.5%), Cherokee 12 (1.3%), Barrow 10 (1.1%), Fayette 10 (1.1%), and Rockdale 10 (1.1%), accounted for 751 (78%) births to HBsAg-positive mothers. Figure 4.6 displays counts of live births to HBsAg-positive women in the 29 counties in the Atlanta MSA. The MSA is based on U.S. Census data and is delineated by the U.S. Of fice of Management and Budget for the purpose of federal data collection and reporting14. The Atlanta MSA is used as a basis for statistical reporting by DPH's HIV Prevention Program and the Department of Community Health.

GEORGIA VIRAL HEPATITIS EPIDEMIOLOGIC PROFILE
Postvaccination Serologic Testing (PVST) Infants and young children (aged <10 years) with HBV are typically asymptomatic, therefore HBV infection may be missed without testing11. Postvaccination serologic testing (PVST) is recommended for infants and children born to HBsAg-positive mothers. Serologic testing confirms whether the child has developed immunity after vaccination or has been infected with HBV despite vaccination. The PVST should include HBsAg and hepatitis B surface antibody (anti HBs). Testing should occur between 9 and 12 months of age.
The Georgia PHBPP case managed 937 HBV-exposed infants born in birth cohorts 2013-2015. (Figure 4.7; detailed data can be found in Appendix Table 4.9)
Figure 4.7: PVST Outcomes for Case-Managed Infants and Children, Georgia, 2013-2015
Case management activities included working with the family to ensure the infant completed the HepB vaccine series and PVST. Of the infants that completed HepB vaccination and PVST, 74% of case managed infants developed adequate antiHBs levels that indicated immunity to HBV. Fewer than 5 case managed infants became infected with HBV. The HBV-infected infants experienced breakthrough infections, despite postexposure prophylaxis.
The Georgia PHBPP continues to have challenges with PVST completion. Many pediatric providers are unfamiliar with the national recommendations and do not order PVST for HBVexposed infants, or do not order within the recommended testing timeframe and either delay testing or test too soon. Additionally, some providers fail to order the HBsAg and anti-HBs laboratory tests together, which makes it difficult to determine an infant's immune status.
Another barrier to completion of vaccination and PVST are clients who are transient and move out of Georgia. In Georgia, we have noted trends of mothers delivering in Georgia and returning to their home countries with the infant soon after birth. Also, cultural practices of having extended family care for a newborn in the mother's home country during the first few years of life present challenges in documenting protective antibody status. These cases are unable to be tracked, leaving these infants vulnerable to HBV infection.

Public Health Implications The Public Health goal is to prevent perinatal HBV transmission. Prenatal care providers can assist DPH with narrowing the gap of missed HBV cases by testing every woman, every pregnancy for HBsAg. Providers and laboratories must report HBsAg-positive pregnant cases to DPH within 7 days of laboratory confirmation; failure to report does not prompt a public health response and places HBV-exposed infants at risk of "falling through the cracks" of public health intervention. Completion of PVST can be challenging due to cultural beliefs or stigmas and the loss of contact with transient populations. Strategies to improve PVST completion rates must be encouraged and implemented through cooperation between the Georgia PHBPP and pediatric care providers, by following national recommendations to order PVST at 9-12 months of age for HBV-exposed infants.

GEORGIA VIRAL HEPATITIS EPIDEMIOLOGIC PROFILE
Hepatitis C
Hepatitis C virus (HCV) is a blood borne pathogen that affects the liver. HCV is spread when blood from someone infected with HCV enters the body of someone that is not infected. The most common route of transmission is through percutaneous exposure (direct passage through the skin). Prior to 1992, before the blood supply was screened for HCV, many people in the U.S. were infected through blood transfusions. The most common routes of transmission include sharing needles, syringes, or other paraphernalia used to prepare or inject drugs; needlestick injuries; or during birth from a mother infected with HCV to the baby. Although less common, someone can also become infected with HCV through tattooing if sterile needles and ink are not used; sexual exposure; or sharing personal items that may have traces of blood. HCV cannot be spread through casual contact.15
Only approximately 25% of people will experience symptoms when first infected with HCV. These symptoms may include fever, fatigue, dark urine, clay-colored stools, abdominal pain, loss of appetite, nausea, vomiting, joint pain, and/or jaundice. It is estimated that 15-25% of people will clear the virus within 6 months of being infected without treatment. However, 7585% will develop a chronic, or lifelong, infection. Chronic HCV infection, if untreated, can lead to serious complications, such as liver damage, cirrhosis, or liver cancer. CDC estimates that there were over 41,000 new (acute) HCV infections in 2016 and that are approximately 2.4 million people in the U.S. living with chronic HCV infection.15
Core Surveillance Available surveillance data from the State Electronic Notifiable Disease Surveillance System (SendSS) was analyzed to determine the burden and epidemiology of HCV in Georgia. Please note that Georgia HCV surveillance data is limited and data depicted below is provisional and may not depict the true burden of HCV in Georgia. Further, due to the large volume of HCV infections reported and lack of program capacity, DPH surveillance efforts focus on those age 30 years and younger; therefore, demographic and risk factor may not be known for the majority of reported HCV infections.
Note that the new case definitions for acute and chronic hepatitis C cases were implemented in 2016. This definition lowers the threshold for inclusion as a case. As a result, increases in acute HCV case counts and rates in 2016 may be, in part, indicative of the change in case counting methodology.
^HCV infections are confirmed acute or chronic based on current CSTE case definitions.
*Total Reported includes confirmed cases as well as those with unknown infection status (positive antibody only reported). Note that negative HCV laboratory results are not reportable in Georgia.

CDC released a new age based testing
recommendation for baby boomers (anyone
born between 1945 and 1965) to be tested
at least once for HCV. This testing
recommendation may explain the increases
in positive labs being reported to the
Georgia DPH.

Between 2012 and 2016, a total of 386 acute HCV infections were identified in Georgia. There was a 55% increase in acute HCV infections from 2012 and 2016. The count and rates of acute HCV have been steadily increasing since 2013. Rates of acute HCV infection were similar to rates being seen for the U.S. U.S. rates were unknown for 2016 at the time of this analysis. (Figure 5.2) Compared to other Southeastern U.S. states,

to increase surveillance capacity so that the epidemiology of acute HCV infections statewide can be better assessed.
Nationally, increases in HCV infections are being seen among young adults, primarily in those between 18 and 30 years of age. Due to the limited capacity surveillance efforts focus on this age group. Figure 5.4 shows a steady increase in total reported HCV in the 18-30 year old age group between 2012 and 2016. Unexpectedly, larger increases in Georgia are being seen in those between 31 and 40 years of age. Due to the limited capacity within the Georgia DPH to conduct epidemiologic investigation, it may be likely that acute HCV infections are not being identified in the 31-40 year old age group. This analysis shows a need

Geographic Distribution of HCV Infections in Georgia National trends have shown that rural areas are seeing the highest rates of acute HCV infections. In 2016, similar trends were seen in the Georgia, with the majority of identified acute HCV infections being seen in rural areas of North Georgia. (Figure 5.10) As expected the majority of chronic HCV infections in 2016 were seen in the metro-Atlanta area; however, rural areas of the state had higher rates of infection, particularly in Southeast and Central Georgia.

In analyzing the geographic location of reported HCV infections, it was determined that many infections were reported from prisons statewide, with the patient's address being the location of the prison rather than the patient's home residence. Therefore, the geographic distribution of the total reported HCV infections were assessed with locations and inmate capacity of state and federal prisons. (Figure 5.13) Between 2012 and 2016, higher rates of HCV infections were reported to DPH from counties that had a prison. There were also higher rates of HCV infection in those counties with prisons with a large inmate capacity. DPH is unable to determine inmates' resident addresses and rely on the address reported by the laboratory, which in many cases is the address of the prison where the inmate is incarcerated.

Figure 5.14: Distribution of Hepatitis C Treatment Providers and Number of Total Reported Hepatitis C Infections (n=51,094) by County, Georgia, 2012-2016
The lack of healthcare providers, especially in rural areas of the state, continues to be a barrier faced by patients in need of HCV care and treatment. Figure 5.14 shows that the majority of HCV patients reside and where the location of healthcare providers are primarily in the metroAtlanta area. South and Central Georgia, however, have very few providers offering HCV care and treatment services. This distribution demonstrates the obvious need for medical providers to manage the care and treatment of HCV-infected persons living outside of the metro Atlanta area.

Hepatitis C Infections by Age Cohort In 2012, the CDC released HCV testing recommendations all adults born between 1945 and 1965 (baby boomers) to receive one-time testing for HCV. CDC estimates that approximately 75% of chronic HCV infections in the U.S. are among baby boomers and that this age cohort is 5 times more likely to be infected with chronic HCV infection than other age groups. Baby boomers also accounted for 73% of HCV-related mortality in the U.S.16
Acute HCV infections had been declining in the U.S until 2010. However, incidence of HCV infections began increasing in 2010 and CDC estimates a 3.5 fold increase in acute HCV infections in the U.S. in 2016. The largest increase of acute HCV infections has been among young adults (those 20-29 years of age), primarily a result of the opioid epidemic and increases in injection drug use.17
Available surveillance data was analyzed reported HCV infections among various age cohorts and determine if trends in Georgia compare to those being seen nationally. As seen in Figure 5.15, 58% of HCV infections

Those born between 1966 and 1986 accounted for 29% of reported infections in 2016, a 6% increase compared to 2012.

between 1966 and 1986 (44%). As expected, the majority (65%) of chronic HCV infections
were among baby boomers. Similar to trends seen in Figure 5.4, these analyses show a need to
increase surveillance efforts in those over 30 years of age.

Perinatal Hepatitis C
Vertical transmission of HCV occurs in approximately 6% of infants born to women infected with HCV. The risk is doubled for infants born to women who are also co-infected with HIV and women who have a high hepatitis C viral load at time of delivery.18 There are currently no biologic interventions to prevent mother-to-child transmission of HCV, as there are for perinatal hepatitis B prevention. With the increase in HCV infections among women of childbearing age, especially those ages 30 years and younger, comes a potential increase in the number of newborns exposed to and infected with HCV during birth.
Approximately 25% to 40% of infected children will spontaneously clear HCV by age 2 years; however, another 6% to 12% may clear the virus before adulthood.19 It is recommended by CDC that exposed infants be tested for HCV antibody after 18 months of age. Testing prior to this age may result in false positive results due to detection of maternal antibodies. As an option, HCV RNA testing can be performed earlier, at age 1 to 2 months and should be repeated after 12 months of age.20 The prevalence of HCV in children is estimated to be between 0.05% and 0.36%.19 This is most likely underestimated, as HCV testing is not routinely conducted during prenatal care, unless a risk factor is known or assessed by the provider. Also, pediatric care providers may not be aware that testing is needed.

Georgia has seen a nearly 60% increase in cases being reported for infants 36 months of age or younger, with only a small
proportion being reported with a confirmed infection (HCV RNA positive). However, further
analysis of reported cases showed that the majority of these children were not tested for HCV
antibody according to CDC recommendations (Table 6.1): only 13% of cases reported to DPH
between 2012 and 2016 were tested appropriately. Georgia does not require reporting of

negative HCV lab results; therefore, DPH is unable to determine how many babies were tested for HCV with negative results.

Viral Hepatitis Testing
One of the keys to addressing the burden of hepatitis B and hepatitis C is by screening to identify those infected with either virus or co-infected with both. Georgia DPH has prioritized viral hepatitis prevention efforts by targeting vaccination and testing conducted at public health clinics and community based organizations as well as supporting hepatitis C screening efforts from external partners.
Public Health Testing Each of Georgia's 159 counties has at least one health department, and public health clinics throughout Georgia have the capacity to conduct viral hepatitis testing through the Georgia Public Health Laboratory (GPHL). Hepatitis A (Total anti-HAV, IgM anti-HAV), hepatitis B (HBsAg, anti-HBs, anti-HBc, HBeAg), and hepatitis C (anti-HCV, HCV RNA/PCR) testing is available through GPHL. In 2013, GPHL began accepting specimens for HCV RNA/PCR testing and in Fall 2016, anti-HCV testing with reflex to HCV RNA/PCR was initiated.
Prior to July 2013, there was no charge to health departments for GPHL to perform hepatitis B testing panels. However, effective July 1, 2013, GPHL began imposing fees for most routine testing, including hepatitis B ($13.50). GPHL charges $10 per test for hepatitis C antibody (antiHCV/EIA with signal to cut-off ratio (s/co) serology and $50.75 for HCV RNA/PCR. Additionally, as of October 2016, anti-HCV with reflex to HCV RNA/PCR was implemented as an option for Public Health clinics, with the cost for HCV RNA/PCR only being charged when it is conducted. Additional administrative fees, as determined by each of the 18 Georgia Health Districts, are charged to patients by the county health departments for all testing services. A sliding fee scale is available, so patients may be charged a reduced amount or no fee at all, if they are unable to afford the current fees.
Figure 7.1: Hepatitis B and Hepatitis C Testing, Georgia Public Health Laboratory, 2012-2016
Source: Data obtained from GPHL.
Data obtained from GPHL shows that although the total number of people tested for HBsAg has decreased dramatically since 2012, the overall positivity rate has remained steady, between 2% and 3%. (Figure 7.1) The decrease in hepatitis B testing at GPHL may be due to the initiation of fees in 2013. Also, a decrease in testing and lower positivity rates among young adults may be partly the result of Georgia's school immunization law, which has required children and students born

GEORGIA VIRAL HEPATITIS EPIDEMIOLOGIC PROFILE
on or after January 1, 1992 to be vaccinated against hepatitis B. That early birth cohort turns 25 years old in 2017, leaving fewer susceptible adults under age 25.
Testing for anti-HCV at GPHL has also decreased slightly since 2012. However, the hepatitis C positivity rate remained stable at 5%-7%, demonstrating that targeted HCV testing for at-risk populations, based on CDC recommendations, is proving to be successful.
Data from GPHL were further examined based on the type of public health clinic where testing was conducted in 2015 and 2016. (Figures 7.2, 7.3) As expected, the highest HBV positivity rates were among those tested in Refugee Health, TB, and HIV clinics. (Note that Refugee Health Clinics also use a commercial laboratory for viral hepatitis testing; therefore, the number of tests shown in Figure 7.2 does not fully represent HBV testing conducted in those sites.) The highest rates of HCV antibody testing were seen in STD and HIV clinics, as well as "other clinic" settings.
Overall, these results show that HBV and HCV testing in public health settings has played an integral part in identifying Georgians infected with HBV and/or HCV. These data will allow DPH to gain a better understanding of the burden of viral hepatitis in Georgia and the need for linkages to HBV and HCV care services, which is necessary to effectively channel resources and improve clinical outcomes among those infected with viral hepatitis.

Hepatitis C Testing Initiative
In 2015, the DPH Hepatitis Program initiated a pilot HCV testing project with community based organizations (CBOs) and health departments. Additionally, since the state FY 2015, the Georgia
Legislature has allotted funds to the DPH Epidemiology Program specifically for HCV testing. This additional funding has allowed DPH to support rapid HCV antibody testing
Figure 7.4: Rapid HCV-antibody Test Sites, Georgia, 2015-2016
within both CBOs and health departments.
Community based organizations that also
provided HIV prevention and testing services
were identified to participate in this testing initiative. Health departments in areas with
high burdens of HCV also participate in this
initiative. Figure 7.4 shows locations of sites
participating in DPH's HCV testing initiative. It is also important to note that rapid HCV
testing has been implemented in health
departments in all four counties identified in
CDC's County-level Vulnerability to Rapid Dissemination of HIV/HCV Infection among Persons who Inject Drugs.21 In 2016, funding
for HCV RNA PCR testing was added for
health department sites. This support has allowed health departments to identify patients with confirmed HCV infection for linkage to additional care and treatment services. All sites used a
rapid HCV testing form developed by the DPH Hepatitis Epidemiology Unit to collect
Figure 7.5: Rapid HCV-Antibody Testing Initiative, Positive Results by Race and Age Group, Georgia, 2015-2016
demographic and risk factor information on all patients who were tested. These data were shared with the DPH Hepatitis Epidemiology Unit for analysis and evaluation of the
initiative.
Overall, 3,315 people were tested under the Rapid HCV-Antibody Testing Initiative during 2015-2016, with a 6% positivity rate. Slightly more than half (56%) of those who tested positive reported male gender; 15% did not report any gender. Of concern is the growing number of HCV infections in young adults. While 36% of participants with positive HCV antibody results were between 50 and 59

years of age not unexpected for baby boomers, 38% were under the age of 40. Of all who tested positive for hepatitis C, 53% were black or African American and 46% were white. (Table 7.1) However, of the positive patients between the ages of 12 and 39 years (n=70), 73% were white. In contrast, of the positive patients aged 40 and older (n=113), 70% were black or African American. (Figure 7.5)

Further analysis based on the setting showed that health departments had a 5% hepatitis C positivity rate, while testing conducted by CBOs yielded a 6% positivity rate. As expected, testing conducted by Atlanta Harm Reduction Coalition, which targets substance users and injection drug users, resulted in a 15% hepatitis C positivity rate. Health department testing yielded the highest positivity rates in the North Georgia Health Districts: District 1-1 (5%), District 1-2 (10%), and District 2 (17%). These three districts include Appalachian populations. The Appalachian region in the U.S. has seen increasing rates of HCV due to the opioid epidemic. It is important to note that all sites began testing at different times, so the data shown are not comparable over the entire time period. (Table 7.2)

Gi lead FOCUS Partnerships i n Georgia In 2010, Gilead Sciences developed the Frontlines of Communities in the United States (FOCUS) program to share best practices in routine bloodborne virus screening, diagnosis, and linkage to care in accordance with CDC's recommended screening guidelines. First launched to address HIV, this public health initiative expanded its scope in 2014 to integrate HCV screening and linkage to care. Further expansion in 2016 added HBV screening and linkage to care in select geographic areas. Together, the FOCUS partners have established a screening and linkage-to-care infrastructure to support individuals and public health. FOCUS partners utilize the Four Pillars of Routine Screening model, TEST (Testing integrated into normal clinical flow; Electronic medical record modification; Systematic policy change; and Training, feedback, and quality improvement), to identify people previously undiagnosed with HIV and HCV and support linkage to care. Since 2010, FOCUS has partnered with more than 300 hospitals, community health centers, health departments, and other health care organizations to advance routine scre ening and diagnosis, connect patients to care, and inform local and national strategies to address bloodborne viruses. Below are highlights of the successes of five FOCUS partners in Georgia.

Through this screening program, 5,239 patients were tested for HCV antibody, yielding an 8% positivity rate. Of the 412 that tested positive for HCV antibody, 60% were male, 94% were black, and 76% were uninsured. The average age of those testing HCV antibody positive was 60 years. (Table 7.3)
Figure 7.15: HCV Care Cascade for Patients Tested through T ILT-C at Grady Memorial Hospital, 2012-2014
*Of 27 patients who had SVR12 lab results available
Twenty months after the completion of TILT-C, charts were reviewed for all 412 HCV antibody positive patients. Ninety-two percent of those with positive HCV antibody results were tested for HCV RNA; 69% of them were confirmed to have current HCV infection. Of this group, 96% were linked to care. Of 82 patients who were referred for treatment, 51% began HCV treatment and 93% of those with data available achieved a sustained virologic response 12 weeks posttreatment. (Figure 7.15)
Of those patients who were linked to care, 49% were referred by the Primary Care Center; 46% were referred to care by the Liver Clinic; and 5% were referred by the Infectious Disease Clinic. (Figure 7.16) Reasons for why patients did not begin HCV treatment varied. The majority (30%) were not treated due to minimal fibrosis and 29% were lost to follow -up; 8% were not treated due to ongoing substance abuse, and 13% chose to await the availability of new HCV treatment options. (Figure 7.17)

GEORGIA VIRAL HEPATITIS EPIDEMIOLOGIC PROFILE
M edicaid Claims for Viral Hepatitis Testing To further assess viral hepatitis testing trends in Georgia, aggregate Medicaid claims data were obtained from the Georgia Department of Community Health (DCH). Data were obtained from both testing and vaccination claims for 2015 and 2016 based on ICD-9 and ICD-10 diagnostic and Current Procedural Terminology (CPT) codes. Unique patient identification numbers were extracted from the total number of Medicaid observations to determine the number of patients tested and subsequently diagnosed with HBV and HCV infection.
There were 181,571 claims related to HBV screening for 66,236 patients between 2015 and 2016 in Georgia. More than half of those tested (53.6%) were between the ages of 15 and 34 years. Although the reason for screening in this age group is unknown based on the data collected, it can be surmised that patients between 15 and 34 years of age may have been tested to assess immunity or susceptibility to HBV, if vaccination history was unknown. Although separate categories are listed for "carrier" and "chronic" hepatitis B infections, the corresponding ICD-10 codes both designate chronic HBV infection. It should also be noted that some of the 102 cases designated as "acute" may not have been truly acute (new) HBV infections, according to CSTE/CDC case definitions, but rather parts of rule-out diagnoses. Due to the nature of aggregate billing data, it is impossible to match them with actual reported cases in SendSS. Nearly 58% of those tested for HBV were black or African American (which may include refugee screening); 24% were white; 5% were Asian or Pacific Islander; and less than 1% reported Hispanic or Latino ethnicity. Of the 702 HBV diagnostic codes claimed with Medicaid, nearly 83% had carrier/chronic HBV diagnoses; 14% had acute HBV diagnoses; and nearly 3% had chronic HBV diagnoses with the delta agent or hepatitis D coinfection. (Table 7.4)
From 2015 to 2016, there were 152,519 claims for HCV testing, for a total of 75,337 patients. Of those, 36% were baby boomers and 37% were ages 30 years or younger. The largest percentages of those tested for HCV were in age groups between 55 and 64 years (22.4%) and between 25 and 34 years (21.6%). Nearly half of all Medicaid patients tested for HCV were black or African American whereas 25% were white. More than half (54%) of those ages 30 years and younger and 45% of baby boomers tested for HCV were black or African American. In contrast, 34% of those ages 30 years and younger were white, compared to 15% of the baby boomers tested for HCV. Similar to hepatitis B, separate categories are listed for "carrier" and "chronic" hepatitis C infections, but both corresponding diagnostic codes designate chronic HCV infection. Overall, 70% of those tested were diagnosed with either acute or chronic HCV infection, including 59% of those ages 30 years and younger and 71% of baby boomers. (Table 7.5)

VIRAL HEPATITIS EPIDEMIOLOGIC PROFILE
Substance Abuse and the Opioid Epidemic
Injection drug use is a growing problem in the United States, with national survey data revealing an increase in first-time heroin use.22 An estimated 2.4 million Americans have experienced substance use disorders related to prescription opioids.23 Recent studies have shown a transition from the nonmedical use of prescription opioids to injected heroin that can be attributed to the development of tolerance to prescription opioids, lower heroin costs, increased heroin potency, simplicity of heroin injection, and stigma against prescription opioid injection.24 Persons who use, abuse, and/or depend on illicit drugs often engage in behaviors that increase the risk for acquiring or transmitting infectious diseases, including viral hepatitis. In fact, viral hepatitis rates are significantly higher among persons who use illicit drugs in comparison to persons who do not use illicit drugs.25
To reduce the risk of transmitting bloodborne infections among persons who inject drugs, several states have legalized community-based public health syringe services programs (SSPs). SSPs offer comprehensive harm reduction services, including sterile injection equipment, safe disposal containers, HIV/viral hepatitis testing, HIV/viral hepatitis treatment linkage, overdose/infectious disease prevention education, substance use disorder treatment referrals, and/or vaccinations. In addition to lowering new HIV and viral hepatitis infections and saving healthcare costs for the treatment of those diseases, these programs have also proven to be effective in decreasing needle stick injuries among first responders; increasing entries into substance use disorder treatment centers; and reducing overdose deaths.26
Currently, there are no Georgia laws that authorize the establishment of SSPs. Georgia law, Title 16. Crimes and Offenses; Chapter 13. Controlled Substances Article 2. Regulation of Controlled Substances; 16-13-32 (Transaction in drug related object) states that it is unlawful for any person or corporation to sell or distribute drug-related objects. This code only allows for pharmacists, pharmacy interns or externs, or practitioners licensed to dispense dangerous drugs to distribute hypodermic needles or syringes. Further, Georgia law, Title 16. Crimes and Offenses; Chapter 13. Controlled Substances Article 2. Regulation of Controlled Substances; 16-13-32 (Possession and use of drug related objects) states that it shall be unlawful for any person to use, or possess, objects or materials for the intent of introducing into the human body marijuana or a controlled substance.
Nationally, the rise in prescription and illicit drug abuse parallels drug overdoses. Overdose deaths, hospitalizations, and emergency department (ED) visits from both prescription and illicit drugs in the United States have been increasing since the 1990s, leading to a national drug overdose epidemic.27 The South US Census region, which includes Georgia, had the highest annual drug overdose death rate for natural/semi-synthetic opioids and prescription opioids in both 2014 and 2015, slightly increasing from one year to the next. Furthermore, national ageadjusted rates of drug overdose deaths from 2010-2015 showed Georgia as one of 30 states
51 | P a g e
VIRAL HEPATITIS EPIDEMIOLOGIC PROFILE
with significant increases.27 These occurrences amplify the potential for increased viral hepatitis incidence and subsequent burden on Georgia's healthcare system.
Tr eatment Episode Data Set (TEDS) The better assess the burden of substance abuse and the opioid epidemic in Georgia, data from TEDS from 2014-2015 was obtained and analyzed from the Substance Abuse and Mental Health Services Administration (SAMSHA), Center for Behavioral Health Statistics and Quality. TEDS includes data that are collected to monitor substance abuse treatment facilities. Those facilities reporting data in TEDS are those that receive funding from the state alcohol and/or drug agency.
TEDS data can offer insight on drug use trends in Georgia; however, there are many limitations to this data, which are listed in Table 8.1. It should also be noted that data obtained from TEDS may include non-Georgia residents.
Nationally, between 2006-2012, there was an increase in confirmed acute HCV infections
among young persons (30 years of age) from nonurban areas, of which approximately 73%
cited injection drug use as a primary risk factor.22 Data from Drug treatment centers in Georgia during 2014 showed that patients 12 to 30 years of age
Figure 8.1: Age at Time of Admission to Drug Treatment Ce nter, by Primary Drug of Use, Georgia, 2014 ( n = 41,338)
represented 35% (n=14,468) of all
admissions; those 31 to 45 years of age
represented 36% (n=14,882); and
patients 45 years of age or older
represented 29% (n=11,988) of the total
admissions for any drug type that year
(Figure 8.1). Although persons aged 12
to 30 made up only 32% of Georgia's
entire population in 2014, this age group constituted 35% of admissions due to tranquilizers/sedatives, 43% due to other opiates, 44% due to

amphetamines, 55% due to heroin, and 62% due to marijuana admissions to drug treatment
centers in Georgia that year. Furthermore, persons aged 31 to 45 made up 24% of Georgia's
entire population in 2014, yet comprised 31% of heroin, 37% of tranquilizers/sedatives, 40% of
other opiates, and 46% of amphetamine admissions in the state that year. Persons older than
45 made up the largest age group proportion (44%) of Georgia's population in 2014, while also
comprising the majority of drug center admissions due to alcohol only (48%) and 49 % of those
due to smoked cocaine.. Georgia patients older than 45 had lower admission percentages for

marijuana, heroin, other opiates, amphetamines, and tranquilizers/sedatives compared to patients aged 12 to 30 and aged 31 to 45 years of age during 2014.
T able 8.1: Limitations to Treatment Episode Data Set (TEDS) Data TEDS is an exceptionally large and powerful dataset. Like all datasets, however, care must be taken that interpretation does not extend beyond the limitations of the data. Limitations fall into two broad categories: those related to the scope of the data collection system, and those related to the difficulties of aggregating data from the highly diverse State data collection systems. Limitations to be kept in mind while analyzing TEDS data include:
TEDS is an admission-based system, and TEDS admissions do not represent individuals. An individual admitted to treatment twice within a calendar year would be counted as two admissions. Most States cannot, for reasons of confidentiality, identify clients with a unique ID assigned at the State level. Consequently TEDS is unable to follow individual clients through a sequence of treatment episodes. TEDS attempts to enumerate treatment episodes by distinguishing the initial admission of a client from his/her subsequent transfer to a different service type (for example, from residential treatment to outpatient) within a single continuous treatment episode. However, States differ greatly in their ability to identify transfers; some can distinguish transfers within providers but not across providers. Some admission records may in fact represent transfers, and therefore the number of admissions reported probably overestimates the number of treatment episodes. The number and client mix of TEDS admissions does not represent the total national demand for substance abuse treatment, nor the prevalence of substance abuse in the general population. The primary, secondary, and tertiary substances of abuse reported to TEDS are those substances which led to the treatment episode, and not necessarily a complete enumeration of all drugs used at the time of admission. In reporting TEDS data, SAMHSA must balance timeliness of reporting with completeness of the data set. States rely on individual facilities to report in a timely manner. States then bundle the data and report them to SAMHSA at regular intervals. Admissions from facilities that report late to the States may appear in a later data submission to SAMHSA. However, the additional submissions are unlikely to have a significant effect on the percentage distributions that are the basis of these tables. States continually review the quality of their data processing. When systematic errors are identified, States may revise or replace historical TEDS data files. TEDS continues to accept data revisions for admissions occurring in the previous five years. While this process represents an improvement in the data, the numbers of admissions reported here may differ slightly from those in earlier or subsequent reports and tables. Considerations specific to these tables include: The tables are based on administrative data reported by States to TEDS through Apr 03, 2015. The tables focus on treatment admissions for substance abusers. Thus admissions for treatment as a codependent of a substance abuser are excluded. Records for identifiable transfers within a single treatment episode are also excluded. Records with partially complete data have been retained. Where records include missing or invalid data for a specific variable, that record is excluded from tabulations of that variable. The total number of admissions on which a percentage distribution is based is reported in each table. Primary alcohol admissions are characterized as Alcohol only or Alcohol with secondary drug. Alcohol with secondary drug indicates a primary alcohol admission with a specified secondary or tertiary drug. All other alcohol admissions are classified as Alcohol only. Cocaine admissions are classified according to route of administration as Smoked and Other route. Smoked cocaine primarily represents crack or rock cocaine, but can also include cocaine hydrochloride (powder cocaine) when it i s free-based. Non-smoked cocaine includes cocaine admissions where the route of administration is not reported, and thus the TEDS estimate of the proportion of admissions for smoked cocaine is conservative. Methamphetamine/amphetamine admissions include admissions for both methamphetamine and amphetamine, but are primarily for methamphetamine. Two States (Oregon and Arizona) do not distinguish between methamphetamine and amphetamine admissions. However, for the States that make this distinction, methamphetamine constitutes about 95 percent of combined methamphetamine/amphetamine admissions.

In addition to substance abuse treatment, these facilities also provide other testing serivces to their patients. A higher percentage of drug treatment centers in Georgia offered testing services compared to the US in 2015, with the exception of breathalyzer/blood alcohol testing (Figure 8.4). This included a higher state percentage for HBV screening (31% GA; 23% US), HCV screening (34% GA; 25% US), and HIV testing (46% GA; 28% US). There was, however, a larger gap between Georgia facilities that offered HIV testing and HBV/HCV screening compared to these facilities nationally.

Georgia DPH Drug Overdose Surveillance
In addition to the drug treatment center data compiled from TEDS, data were obtained from the Georgia DPH Drug Overdose Surveillance Unit (https://dph.georgia.gov/drug-overdosesurveillance-unit) to describe fatal (mortality) and nonfatal (morbidity) opioid-involved overdoses, including prescription opioids, and illicit opioids such as heroin and synthetic opioids (e.g., fentanyl and fentanyl analogs), which occurred in Georgia during 2016. Opioid overdose data were analyzed by the Georgia Department of Public Health (DPH) Epidemiology Section, using Georgia hospital discharge inpatient and emergency department (ED) visit data, and DPH Vital Records death data. Case definitions for this mortality and morbidity data can be found in Table 8.2 and Table 8.3, respectively. Data shared below was adapted from the 2016 Georgia Opioid Overdose Surveillance Preliminary Report.

Opioid-Overdose Related Mortality Illicit opioids, such as heroin and fentanyl, drove the sharp increase in overall opioid-involved overdose deaths in GA, beginning in 2013. From 2010 to 2016, the number of opioid -involved overdose deaths increased by 117% in Georgia, from 426 to 929 deaths. (Figure 8.5). Since 2013, illicit opioids, such as heroin and fentanyl, has contributed to sharp increases in opioid involved overdose deaths.
The highest numbers of heroin- and opioid-involved overdose deaths, ED visits, and hospitalizations occurred predominantly in urban areas (Atlanta Metropolitan Area, Augusta, Macon, Columbus, and Savannah). However, high rates of opioid overdose -involved ED visits and hospitalizations occurred in both urban and rural areas, particularly in North, South Central, and Southeast Georgia.

Mortality Related to Viral Hepatitis, Georgia, 2010-2015
In 2013, annual HCV-related mortality in the US exceeded the total number of combined deaths from 60 other reportable infectious diseases, including HIV, pneumococcal disease, and tuberculosis. However, the actual number of these deaths was likely higher, as the data were collected from death certificates where HCV is often underreported as a cause of death.28
To assess the burden of viral hepatitisrelated mortality in Georgia, death certificate data from 2010-2015 were collected based on corresponding ICD-10 codes for HBV, HCV, and HIV as causes and contributing factors leading to death. ICD10 codes are assigned by the CDC, National Center for Health Statistics (NCHS) by extracting textual data obtained from Vital Records. Analysis of these data includes the first five reported ICD-10 codes for each decedent. The first ICD-10 code listed is the primary cause of death, with the following four codes listed being contributing factors.
Figure 9.1: Deaths Documenting HBV*, HCV**, or HIV*** as a Cause or Contributing Condition to Death, Ge orgia, 2010-2015
Georgia mortality rates for HCV-related conditions were lower than HIV-related deaths and much higher than HBV-related deaths. However, from 2010 to 2015, HIVrelated death rates greatly decreased each year (5.8/100,000 population in 2010 to 4.2/100,000 population in 2015) while HCV-related death rates increased from 2010 (3.0/100,000 population) to 2014 (4.0/100,000 population).

national trends, HCV-related death rates in Georgia decreased slightly from 4.0 per 100,000
population in 2014 to 3.7 per 100,000 population in 2015. In contrast with HCV and HIV
mortality trends, HBV-related death rates in Georgia during 2010-2015 showed little change per
year (average rate of 0.4/100,000 population). (Figure 13.1) It is important to note that, as with
national mortality data, the number of deaths related to viral hepatitis in Georgia is most likely
underreported.

VIRAL HEPATITIS EPIDEMIOLOGIC PROFILE
HAV does not cause chronic infection and, therefore, it is rare for acute HAV infection to result in death. However, further analysis of these data showed HAV documented as a cause or contributing condition to death for 13 Georgia decedents during 2010-2015.
Research has shown that individuals chronically infected with HCV have an estimated 12 times higher mortality rate than the general US population.29 From 2000-2015, Georgia's age-adjusted mortality rates for HCV were lower than those in the US, but deaths from HCV in the state did increase steadily from 2009-2012 prior to hitting a peak state rate of 1.7 per 100,000 population in 2014. The annual age-adjusted mortality rates for hepatitis C in Georgia have exceeded those for HIV since 2012. (Figure 13.2)
Figure 9.2: Age-adjusted Mortality Rates for H IV* and HCV**, Georgia and U.S., 2000-2015
In 2015, the highest burden of HCV-related deaths in the United States was among those ages 55-64 years (23.7 deaths per 100,000 population).30 The largest proportion of HCVrelated deaths in Georgia from 2010-2015 also

occurred among the 55-64 age group and was predominantly male. This is not surprising, as national surveillance data show that chronic HCV infection affects more males than females, especially among baby boomers.30 Approximately 91% of all HCV-related deaths in Georgia from 20102015 occurred among those between the ages of 45 and 74 years, 74% of which were male. (Figure 13.3) These age groups include the baby boomer population (those born between 1945 and 1965), representing approximately 75% of chronic HCV infections and 73% of HCV-related mortality in the US.31 The high mortality rate for Georgians in this age group may indicate late diagnosis of HCV and demonstrates the

importance of testing, early detection, and need for access to HCV care and treatment for baby boomers.
Georgia's proportion of HCV-related deaths by race from 2010-2015 was distributed similarly to the state's population in 2015. From 2010-2015, the majority of HCV-related deaths in Georgia were white (n=1,628), followed by black/African-American (n=859), Asian/Native Hawaiian/Pacific Islander (n=32), American Indian/Alaska Native (n=4), and multiracial (n=4).

Hospitalizations and Emergency Room Visits Related to Viral Hepatitis
Studies have indicated that persons living with viral hepatitis in the US can easily spend hundreds of thousands of dollars on health care costs in their lifetime .34 To better assess the burden of viral hepatitis morbidity in Georgia, data about inpatient hospitalizations and emergency room visits related to HBV and HCV in Georgia from 2010 to 2014 were compiled from DPH's Online Analytical Statistical Information System (OASIS) using corresponding ICD-9 codes. Specific ICD-9 codes used are listed below (Table 10.1). It should be noted that morbidity data represented in this profile were analyzed by the number of visits rather than by the number of patients; therefore, each visit to an emergency room and each hospitalization was included in the analysis.

Between 2010 and 2014, there were 28,304 HBV-related hospitalizations and 111,328 HCV-related hospitalizations in Georgia. During this time, hospitalization rates for HBV decreased slightly from 30.1/100,000 population in 2010 to 27.1/100,000 population in 2014. HCV-related hospitalization rates were less consistent, decreasing from 2010 (118.7/100,000 population) to 2011 (106.1/100,000 population); increasing in 2013 (116.8/100,000 population); and then decreasing once again in 2014 (110.3/100,000 population). (Figure 10.1)
There were 52,176 HBV-related and 83,054 HCV-related emergency room visits in Georgia between 2010 and 2014. Emergency room visit rates for HBV increased from 2010 (53.1/100,000 population) to 2012 (55.8/100,000 population), but then decreased in 2014 (49.3/100,000 population). HCV-related emergency room visit rates did not fluctuate much between 2010 and 2014, averaging 83.8 per 100,000 population and peaking at 84.8 per 100,000 population in 2014. (Figure 10.2)

inpatient hospitalizations (n=55,664) between 2010 and 2014 were analyzed by payor type. The
majority of HCV-related emergency room visit costs were covered by self-pay (30%), Medicaid (28%), and Medicare (25%). For HCV-related hospitalizations, the

(32%), Medicaid (29%), and private insurance
(18%). Approximately 1% (n=470) of all
emergency room visits and hospitalizations
associated with HCV in Georgia from 2010 to
2014 had an unknown payor type and 5%
(n=4,750) were in an "other payor" category,
which included 19 PeachCare visits. (Figure

Viral hepatitis health care costs have often
been associated with comorbidities, such as HIV
and substance abuse disorders.37 In fact,
studies have found viral hepatitis to be one of
the most prominent causes of morbidity and
mortality among persons living with HIV in the
US.38 To further assess the burden of viral
hepatitis and HIV morbidity in Georgia, ICD-9
codes for HIV-related inpatient hospitalizations
from 2014 were compiled and compared to

HBV- and HCV-related hospitalizations that occurred within the same year. There were 268,353 total HIV-related hospitalizations
statewide in 2014, 36% of which were among
baby boomers. The age breakdown of Georgia hospitalizations in 2014 differed by disease, with
nearly half of hospitalizations related to HBV occurring in 45-64 years age group. The majority
of HCV-related hospitalizations were in the 55-64 years age group (37%) and HIV-related
hospitalizations in the 65-74 years age group (22%). (Figure 10.4; Table 10a) Racial disparities
are noted in these data. Persons hospitalized in Georgia for HCV and HIV in 2014 were
predominantly White (59% and 61%, respectively). (Figure 10.5) However, Blacks and African
Americans in Georgia were disproportionately affected, as this population represented 32% of

the state's population in 2014, yet comprised 45% of HBV-related hospitalizations, 36% of HCV-related hospitalizations, and 35% of HIV-related hospitalizations in the same year. Similar to national trends that have shown Asian and Pacific Islanders to be disproportionately affected by HBV, Asian/Native Hawaiian/Pacific Islanders in Georgia made up 6% of hepatitis B-related hospitalizations in 2014, yet constituted only 4% of the state's total population that year. Of the 1,552 acute HCV cases reported nationally in 2015, approximately 53% reported hospitalization as a result of HCV infection.39

In Georgia, approximately 34% of the 55,664 HCV-related inpatient hospitalizations from 2010 to 2014 listed HCV as a primary, secondary, or tertiary diagnosis. (Figure 10.6) Moreover, the leading primary admittance diagnoses among HCV-related hospitalizations in the state during this time were encounters for antineoplastic chemotherapy, chronic HCV with hepatic coma, and pneumonia (organism unspecified).

GEORGIA VIRAL HEPATITIS EPIDEMIOLOGIC PROFILE
To better assess the geographic distribution of HCV morbidity in Georgia, counts and rates of inpatient hospitalizations with documented primary or secondary diagnoses of HCV from 2010 to 2014 were mapped by County. (Figure 10.7) Counties with the highest counts of primary or secondary diagnoses for HCV during this time were mostly in the Atlanta metro area: Fulton (n=1,330), DeKalb (n=895), Cobb (n=883), and Gwinnett (n=719) Counties. The fifth-highest count was Chatham County (n=432), which is located in the southeastern coastal region of the state. The geographic distribution of these HCV diagnoses were quite different when adjusted by county population size, with three of the top five counties located in northern Georgia (Stephens at 290.4/100,000 population, Banks at 246.0/100,000 population, and Pickens at 226.1/100,000 population) and the two remaining counties located in middle Georgia (Butts at 231.1/100,000 population and Wilcox at 226.1/100,000 population).

Figure 10.8: Proportion of Inpatient H ospitalizations Documenting Diagnoses of H CV*, by Age Group, Georgia, 2010-2014
Chronic manifestations of HCV are expected to increase in the US, since 75% of those infected are within the aging baby boomer cohort.38 In line with this national prediction, patients between the ages of 46 and 65 years comprised 70% of those hospitalized with HCV-related primary diagnoses and 65% of all HCV-related diagnoses in Georgia during 2010-2014. (Figure 10.8)
*Refer to Table 10.1 for data sources. Note: 3,177 visits were excluded from the dataset due to unknown age
Males made up approximately 62% of those hospitalized with primary diagnoses of HCV and 60% of all diagnoses of HCV in Georgia during 2010-2014. (Figure 10.9) When stratified by age, however, Georgia females within the younger cohort for HCV (between 18 and 30 years of age) had slightly higher annual percentages of HCVrelated hospitalizations than their male counterparts from 2010-2014. (Figure 10.10)

GEORGIA VIRAL HEPATITIS EPIDEMIOLOGIC PROFILE
The majority of both primary (68%) and all (59%) diagnoses for HCV hospitalizations in Georgia
from 2010-2014 occurred among Whites, followed by Blacks and African Americans (primary
diagnoses at 27% and all diagnoses at 37%), multiracial (primary diagnoses at 4% and all
diagnoses at 3%), and Asian/Native Hawaiian/Pacific Islanders (primary diagnoses at 1% and all diagnoses at 1%). (Figure 10.11) American Indian/Alaska Natives comprised
Figure 10.11: Proportion of Inpatient H ospitalizations Documenting Diagnoses of H CV*, by Race, Georgia, 2010-2014
only 0.07% of primary diagnoses and 0.25% of
all diagnoses for HCV hospitalizations in
Georgia for the same years. The higher
percentage of primary HCV diagnoses seen
among Whites in Georgia from 2010-2014 may
reflect the increased incidence of acute
hepatitis C cases seen within that population
during the same time.

In the US, the leading cause of liver disease and
most common reason for liver transplantation is
viral hepatitis.40 It often takes decades for any
signs or symptoms to appear in chronic
hepatitis C patients, at which point liver scarring
(cirrhosis), end-stage liver disease, or liver
cancer (hepatocellular carcinoma) could
occur.37 An estimated 10%-20% of chronic
hepatitis C patients develop progressive liver
damage over a time period of two to three
decades.41 When corresponding ICD-9 codes for
hepatitis C-related hospitalizations in Georgia
*Refer to Table 10b in Appendices for data sources.
from 2010-2014 were grouped and categorized
by liver disease type, the majority of diagnoses
were in the "Other Chronic Liver Disease" category (37%), followed by "Cirrhosis" (31%),
"Decompensated Cirrhosis" (25%), "Liver Cancer" (5%), and "Liver Transplants" (1%). (Figure

Liver Cancer in Georgia
The Annual Report to the Nation on the Status of Cancer, 1975-2012 (ARN), reported that liver
cancer rates in the US increased by 72% between 2003 and 2012. Further, there has been a
56% increase in mortality related to liver cancer in the US since 2003. One of the main types of
liver cancer is hepatocellular carcinoma (HCC), over 60% of which, globally, is attributed to HBV and/or HCV infections.42 In the U.S., 15% of liver cancer incidence is related to chronic HBV

14%
infection and 50% is related to chronic HCV
infection.43 The ARN also indicated that HCV and
liver cancer-associated death rates were the
highest among baby boomers.42
Based on data from the Georgia Comprehensive
Cancer Registry (GCCR), 86% of new liver cancer
86%
diagnoses in GA are HCC. (Figure 11.1) Overall,
males had higher incidence rates of liver cancer than females, across all age groups. Liver cancer

Incidence rates of liver cancer are highest among the Asian/Pacific Islander (API) population both in Georgia and in the US. However, rates have been decreasing in this population in Georgia since 2012. Rates among both US and GA non-Hispanic (NH) Blacks have been increasing (5.3% per year and 5.1% per year, respectively) during the past decade, though this trend appears to have slowed down in more recent years. Similarly rates among US and GA NH

Georgia incidence rates of HCC have remained lower than US rates among both males and females since 2000. Rates among both US and GA males increased significantly during the 2000s (5.2% per year and 6.9% per year respectively) but appear to have leveled off in more recent years. Among US and GA females, incidence rates are lower than t hose for males but have also been significantly increasing (3.5% per year for US females and 6.1% per year for GA females). (Figure 11.4) Data is not currently available to determine how many Georgia HCC cases are also infected with HBV and/or HCV.

Incidence rates of liver cancer in Georgia are highest among males across all age groups and race/ethnicities. API males, especially those over the age of 60 years, have the highest rates of liver cancer. Liver cancer incidence is also high among API females over the age of 60 years, compared to NH black and NH white females. Liver cancer rates are also high among NH black males, especially those between the ages of 60 and 69. (Figure 11.5)

VIRAL HEPATITIS EPIDEMIOLOGIC PROFILE
Liver cancer rates generally increase with age, but this increase has been especially pronounced among people born between 1945 and 1965, otherwise known as "Baby Boomers". This generation experienced high rates of Hepatitis C during the 1960s through the 1980s before the virus was discovered and preventive measures became possible . In 2014, male Baby Boomers accounted for more than half of all new liver cancer cases in Georgia. (Figure 11.7)

Stage of disease refers to the extent to which cancer has spread when diagnosed. In general, the earlier the stage, the better the chance for survival. In Georgia, nearly half of all liver cancers are diagnosed at a late stage, regardless of sex, race, or tumor subtype. During the years 2007-2013, 59% of Georgians diagnosed with HCC at an early stage survived at least one year; that figure dropped to 24% for those diagnosed at a late stage. For Georgians diagnosed with other types of liver cancer during that same time period, 27% of early stage cases and 17% of late stage cases survived one year. (Figure 11.8)
