Outbreaks of hepatitis A have been occurring in states across the country since 2016, and they don’t appear to be slowing down.

Since May 2019, Minnesota has seen an increase of hepatitis A cases, which we have now identified as an outbreak. Minnesota's outbreak-associated cases have risk factors consistent with the national outbreaks.

People at high risk in the current outbreaks include:

  • People who use injection/non-injection drugs.
  • People experiencing homelessness or unstable housing.
  • People who are currently or were recently incarcerated.
  • Men who have sex with men (MSM).

The best way to prevent hepatitis A infection is through vaccination.
