The outbreak total is now 1239 since it started in 2018. Eight cases have died as a direct result of hepatitis A infection.  Since January 1, 2018, 97% of cases have likely been acquired locally in Florida.

In March, hepatitis A cases were reported from 25 counties. The central Florida region had the highest hepatitis A activity levels. 91 (34%) cases were co-infected with chronic hepatitis B or C. Co-infection with more than 1 type of viral hepatitis can lead to more severe liver disease and increase the risk of developing liver cancer.

The best way to prevent hepatitis A infection is through vaccination. Since January 1, 2018, 97% of people with hepatitis A had never received a documented dose of hepatitis A vaccine. In March 2019, 96% of infected people had not received the vaccine.
