Summary
The capacity for notifying CDC of acute hepatitis B cases varies considerably based on laws, resources, and infrastructure for conducting viral hepatitis surveillance in each jurisdiction. In 2022, no cases of acute hepatitis B were reported to CDC by Connecticut, Hawaii, or New Mexico.
The national rate of reported acute hepatitis B was 0.6 cases per 100,000 population during 2022. West Virginia had the highest rate of acute hepatitis B during 2021 (3.0 cases per 100,000 population), followed by Florida (2.4 cases per 100,000 population) and Maine (2.1 cases per 100,000 population). Florida also reported the largest number of cases (n = 642), approximately 30% of the total number of acute hepatitis B cases reported in the United States during 2022.
