Hepatitis A virus infects the liver and can cause illnesses that range from a mild infection that has no symptoms to a more severe illness that can last for months. In rare occasions, it can cause liver failure and death.
Hepatitis A virus spreads easily. It gets into the body through the mouth after someone touches an object, food, or drink that is contaminated with the virus.
If an infected person doesn’t wash their hands well, especially after using the toilet, undetectable amounts of the virus can spread from the hands of that person to other objects, surfaces, and foods.
Most cases occur through eating contaminated food.
On November 29, 2021, the WA State Dept. of Health and Public Health – Seattle & King County reported that the hepatitis A outbreak among people living homeless appeared to be over.

Hepatitis A vaccination is the best way to prevent hepatitis A. The shot is safe and effective; anyone who wants to reduce their risk of hepatitis A should get vaccinated. Anyone who is in the higher risk groups should be sure to get the hepatitis A vaccine to protect themselves.
Hepatitis A vaccinations can also be used to help prevent illness from hepatitis A among those who may have been exposed to the virus if given within two weeks of exposure.
Practicing good hand hygiene – including thoroughly washing hands after using the bathroom, changing diapers, and before preparing or eating food – also plays an important role in preventing the spread of hepatitis A. People in high risk groups should also avoid sharing food, drinks, drug equipment (works), and other personal items.
To get a hepatitis A vaccine, visit your doctor, nurse, or clinic. You can also check www.vaccinefinder.org for pharmacies that offer hepatitis A vaccine. Check our Healthcare for the Homeless Network page for information about vaccination locations for people living homeless or people who use street drugs.
