The capacity for notifying CDC of acute hepatitis B virus infection cases varies considerably on the basis of laws, resources, and infrastructure for conducting viral hepatitis surveillance in each jurisdiction. The national rate of acute hepatitis B was 1.0 reported cases per 100,000 population during 2019. Maine had the highest reported rate of acute hepatitis B during 2019 (4.3 cases per 100,000 population). Five states with the highest number of reported acute cases (Florida, Ohio, Tennessee, Kentucky, and North Carolina) accounted for approximately half of the national burden of acute hepatitis B cases reported during 2019.
