There is an outbreak of hepatitis A among adults in Washtenaw and other Michigan counties. The hepatitis A vaccine is extremely effective at preventing infection, but the majority of Washtenaw adults have not been vaccinated (70%). Vaccination and good handwashing can prevent the spread of illness.

Sharing Information about Risks
Hepatitis A is a serious, highly contagious liver disease caused by the hepatitis A virus. The virus is found in the feces (poop) of people with hepatitis A. It is spread by eating contaminated food or water, during sex, or from close contact with an infected person.
People experiencing homelessness, using illegal drugs, and men who have sex with men are considered at higher risk in the current outbreak. But, there are also cases of hepatitis A among people without these known risks (40% statewide). Washtenaw County Health Department encourages all adults to consider vaccination.
Washtenaw County Health Department can provide vaccination. Walk in Monday, April 9 from 6-8 pm. Or, call 734-544-6700 to schedule an appointment.
Walk-ins continue on the 2nd and 4th Mondays through April. Appointments remain available by calling 734-544-6700.
Vaccination is recommended for anyone not already vaccinated, and especially recommended for:
- People at higher risk of exposure to hepatitis A, including men who have sex with men, those with a history of substance abuse, those currently homeless or in transient living, correctional facility inmates, and those with underlying liver disease
- Food service workers
- Healthcare workers or first responders
- Anyone who may have been exposed to hepatitis A
There is no additional charge for the hepatitis A vaccine if you are uninsured, have Medicaid, or are at higher-risk of exposure. If you have health insurance, please check with your health care provider or pharmacy first.
Making Vaccination Widely Available
Washtenaw County Health Department is working with service providers, nonprofits, and restaurants to offer vaccination at community locations. If your organization or business is willing to host a vaccination clinic, please contact us.
Washtenaw County Health Department and area health care providers have given over 8,400 hepatitis A vaccinations to local adults since October 2017 (Michigan Department of Health and Human Services).
Contacting Anyone that may have been exposed to Hepatitis A
This is done to alert individuals to the symptoms and to provide vaccination. Vaccination within two weeks of exposure can prevent infection.
About Hepatitis A
Hepatitis A is caused by the hepatitis A virus, and it can cause damage to the liver and other health problems. Hepatitis A can range from a mild illness lasting a few weeks to a serious illness lasting several months.
Symptoms of hepatitis A include fatigue, poor appetite, stomach pain or tenderness, nausea or vomiting, dark urine, and yellowing of the skin (jaundice). Most children less than 6 years do not experience symptoms. Symptoms typically appear 2 to 6 weeks after exposure. Individuals with symptoms should call their provider or seek care.
How is it spread?
The virus is found in the feces (poop) of people with hepatitis A. Most infections result from contact with an infected household member or sex partners. The virus can also be spread by consuming food or drink that has been handled by someone with hepatitis A. It is not spread through coughs or sneezes. Someone who has hepatitis A can spread it to others for up to 2 weeks before symptoms appear.
The best way to prevent hepatitis A is to get vaccinated. One dose is almost 95 percent effective at preventing infection, according to the Centers for Disease Control and Prevention (CDC). Since 2006, the hepatitis A vaccine has been routinely recommended for children. But, only 30% of adults in Washtenaw County have been vaccinated against hepatitis A - which means the majority of local adults are not vaccinated.
Frequent handwashing with soap and warm water after using the bathroom and before handling food can also help prevent the spread of hepatitis A. Freezing does not kill the virus.
