Hepatitis A is a contagious liver disease that results from infection with the Hepatitis A virus. It can range in severity from a mild illness lasting a few weeks to a severe illness lasting several months. Hepatitis A is usually spread when a person ingests fecal matter — even in microscopic amounts — from contact with objects, food, or drinks contaminated by the feces, or stool, of an infected person.

Southeast Michigan has seen an increase in Hepatitis A cases since 2016. High risk individuals identified in association with this outbreak include persons who: share injection and non-injection street drugs (including pain killers), have sexual activities with someone who has hepatitis A, have close contact, care for, or live with someone who has Hepatitis A, are homeless or have transient living situations, or are men who have sex with men.
