Hepatitis A is a serious and contagious liver disease caused by a virus. It is spread by not washing hands after using the bathroom and getting the germs into your mouth. The disease can range from a mild illness lasting a few weeks to a severe illness lasting several months. Hepatitis A is not a lifelong infection like other types of hepatitis can be. Once you get it, you cannot get it again.
