The Michigan Department of Health and Human Services (MDHHS) reported last week they continue to see an elevated number of hepatitis A cases in the state.
Since the beginning of the outbreak in August 2016 through February 14, 751 cases, including 609 hospitalizations have been reported. This includes 25 fatalities.
Macomb County has seen the most cases (210), followed by the city of Detroit (161), Wayne County (131) and Oakland County (99).
The public health response has included increased healthcare awareness efforts, public notification and education, and outreach with vaccination clinics for high-risk populations.
No common sources of food, beverages, or drugs have been identified as a potential source of infection. Transmission appears to be through direct person-to-person spread and illicit drug use. Those with history of injection and non-injection drug use, homelessness or transient housing, and incarceration are thought to be at greater risk in this outbreak setting. Notably, this outbreak has had a high hospitalization rate.
