§ Numbers reported in each category may not add up to the total number of reported cases in a year due to 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. Large central metro, large fringe metro, medium metro, and small metro 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 ten . For the purposes of this report, regions with US territories (Region 2 and Region 9) contain data from states only.

This table summarizes the epidemiology of acute hepatitis C in the United States. During 2020, rates of acute hepatitis C were highest among persons aged 20–49 years, males, American Indian/Alaska Native persons, and those living 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 for Health Statistics, from 2019 to 2020 the rates of reported cases of acute hepatitis C increased in urban settings, but in 2020 rates remained slightly higher in rural settings compared with urban settings. Among all acute hepatitis C cases reported during 2020, 57% occurred among persons aged 20–39 years, 72% occurred among non-Hispanic White persons, and 84% occurred in urban areas.
