The capacity for notifying CDC of acute hepatitis B virus infection cases varies considerably based on laws, resources, and infrastructure for conducting viral hepatitis surveillance in each jurisdiction. In 2021, no cases of acute hepatitis B were reported to CDC by Connecticut or Hawaii, and cases from the District of Columbia and Rhode Island were unavailable.
The national rate of reported acute hepatitis B was 0.6 cases per 100,000 population during 2021. West Virginia had the highest rate of acute hepatitis B during 2021 (3.0 cases per 100,000 population), followed by Florida and Maine (2.4 cases per 100,000 population, respectively); Florida also reported the largest number of cases (n = 531).
