Rates* of reported cases† of acute hepatitis B, 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 changes in denominator and should be interpreted with caution (see Technical Notes).
† Reported confirmed cases. For the case definition, see Acute Hepatitis B.
Summary
Rates of reported acute hepatitis B decreased among all race and ethnicity groups from 2007–2012, remained largely unchanged during 2013–2019, then declined abruptly among all race and ethnicity groups in 2020. In 2022, rates of reported cases of acute hepatitis B ranged from a low of 0.3 cases per 100,000 among non-Hispanic Asian/Pacific Islander (A/PI) persons to a high of 1.0 cases per 100,000 among non-Hispanic Black persons. Compared to 2021, rates increased in 2022 among non-Hispanic A/PI persons and non-Hispanic Black 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).
