Hepatitis A is a preventable, communicable disease of the liver caused that can range from a mild illness lasting a few weeks to a severe illness lasting several months. Although rare, Hepatitis A can cause death in some people. Hepatitis A usually spreads when a person unknowingly ingests the virus from objects, food, or drinks contaminated by small, undetected amounts of stool from an infected person.
Most people who get hepatitis A feel sick for several weeks, but they usually recover completely and do not have lasting liver damage. In rare cases, Hepatitis A can cause liver failure and death; this is more common in people older than 50 and in people with other liver diseases.
