- Eating food-particularly food that is raw or not thoroughly cooked (shellfish, for example)-that has been handled or prepared by someone who has hepatitis A.
- Drinking water or ice that is contaminated with feces.
- Engaging in oral-anal sex ("rimming") with someone who has hepatitis A.
- Coming in contact with blood-to-blood exposure (sharing intravenous drug injection equipment, for example). However, HAV is rarely spread through this type of exposure.
Hepatitis A is an acute form of hepatitis, meaning that it does not cause long-term (chronic) infection. If you have had hepatitis A once, you cannot be infected with the virus again. However, you can still be infected with other hepatitis viruses (hepatitis B virus and hepatitis C virus, for example).
