* Rates per 100,000 population. Beginning in 2021, single-race population estimates are used for rate calculations. For prior years, bridged-race population estimates are used. When comparing the 2021 rates by race/ethnicity to prior years, differences may be due to the change in denominator and should be interpreted with caution (see Technical Notes).
† Reported confirmed cases. For the case definition, see .
§ 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 regions were categorized according to the grouping of states and US territories assigned under each of the 10 . 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 2021, rates of acute hepatitis C were highest among persons aged 20–49 years, males, non-Hispanic American Indian/Alaska Native persons, and those living in 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 2020–2021 the rates of reported cases of acute hepatitis C increased in urban settings, but in 2021 rates remained slightly higher in rural settings compared with urban settings. Among all acute hepatitis C cases reported during 2021, 52% occurred among persons aged 20–39 years, 68% occurred among non-Hispanic White persons, and 84% occurred in urban areas.
