Rates* of reported cases† of acute hepatitis B, by age group — United States, 2007–2022
* 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.
† Reported confirmed cases. For the case definition, see Acute Hepatitis B.
Since 2011, rates of reported cases of acute hepatitis B remained low and decreased among children and adolescents aged 0–19 years and persons aged 20–29 years. This is likely explained, in part, because of the implementation of childhood hepatitis B vaccine recommendations first issued in 1991. Because the cohort of persons vaccinated as infants and children have grown older, the rate of acute hepatitis B among persons aged 30–39 years began to consistently decrease beginning in 2015.
Conversely, rates of reported cases of acute hepatitis B among persons aged 40–49 years, 50–59 years, and 60 years and older steadily increased during 2015–2019. In 2020, rates declined in all adult age groups and persisted through 2021. In 2022, the highest rates were among persons 40–49 years (1.4 cases per 100,000 population) and 50–59 years (1.2 cases per 100,000 population). Compared to 2021, rates among persons aged 50 years and older increased, whereas rates among persons aged 30–49 years decreased.
