The rate of reported hepatitis A in the United States was 5.7 per 100,000 population during 2019, approximately 1.5 times the rate reported during 2018 and >14 times the rate reported during 2015, before the widespread person-to-person outbreaks were first reported. The 5 states with the highest number of reported cases during 2019 (Florida, Tennessee, Ohio, Indiana, and Kentucky) account for >10,000 reported cases of hepatitis A, approximately half the national burden during 2019. These states were heavily affected by the person-to-person hepatitis A outbreaks during that year.
