Rates* of reported cases† of acute hepatitis C, by race/ethnicity — United States, 2007–2022
Source: CDC, National Notifiable Diseases Surveillance System.
* 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 and 2022 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 Acute Hepatitis C.
Summary
Compared with 2007, rates in 2022 were substantially higher among all race and ethnicity categories. During 2022, rates of reported cases of acute hepatitis C ranged from a low of 0.3 cases per 100,000 population among non-Hispanic Asian/Pacific Islander (A/PI) persons to a high of 2.9 cases per 100,000 population among non-Hispanic American Indian/Alaska Native (AI/AN) persons. From 2021–2022, rates increased among non-Hispanic AI/AN, non-Hispanic Black, and Hispanic persons; remained stable among non-Hispanic A/PI persons; and decreased among non-Hispanic White persons. Variations of disease rates by race or ethnicity may reflect systemic cultural, behavioral, environmental, and social factors, including structural racism.
Fluctuations in annual rates may result, in part, from the relatively smaller number of cases reported among some race and ethnicity categories and a change from using bridged-race (2020 and prior) to single-race (2021 and after) population estimates as denominators for rate calculations (see Technical Notes).
