§ Numbers reported in each category might not add up to the total number of reported cases in a year because of cases with missing data or, in the case of race/ethnicity, cases categorized as “Other.”
¶ Urbanicity was categorized according to the 2013 National Center for Health Statistics (NCHS) urban-rural classification scheme for counties and county-equivalent entities (https://www.cdc.gov/nchs/data_access/urban_rural.htm). Large central metropolitan, large fringe metropolitan, medium metropolitan, and small metropolitan counties were grouped as urban. Micropolitan and noncore counties were grouped as rural.
# US Department of Health and Human Services (HHS) regions were categorized according to the grouping of states and US territories assigned under each of the 10 HHS regional offices (https://www.hhs.gov/about/agencies/iea/regional-offices/index.htmlexternal icon). For the purposes of this report, regions with US territories (Regions 2 and 9) contain data from states only.

This table summarizes the epidemiology of hepatitis A in the United States during recent years, highlighting the populations most affected by outbreaks of hepatitis A occurring among persons who use drugs and persons experiencing homelessness. During 2019, rates of reported hepatitis A were highest among persons aged 20–49 years, males, non-Hispanic White persons, and in the US Department of Health and Human Services Region 4 (Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, and Tennessee). Using urbanicity categories defined by the National Center of Health Statistics, compared with the preoutbreak period of 2015, the rates of hepatitis A in 2019 increased 13 times in urban settings and 18 times in rural settings. Among all hepatitis A cases reported during 2019, 75% occurred among persons aged 20–49 years; 73% occurred among non-Hispanic White persons; 78% occurred in urban areas; and 47% occurred in Health and Human Services Region 4.
