Rates* of reported cases of hepatitis A, 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 A.

Compared with the pre-outbreak period of 2015, the rates for reported hepatitis A increased most dramatically among non-Hispanic White persons during 2017–2019, then decreased by 85% among non-Hispanic White persons during 2020–2022 but remained above the pre-outbreak 2015 rate. During 2022, rates of hepatitis A ranged from a low of 0.5 cases per 100,000 population among non-Hispanic Asian/Pacific Islander persons to a high of 1.0 cases per 100,000 population among non-Hispanic American Indian/Alaska Native 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).
