Show full transcript for What is Hepatitis A video

Hepatitis A is a highly contagious liver infection caused by the Hepatitis A virus (HAV). It is present in the feces of infected persons and is most often transmitted through consumption of contaminated water or food. Most people in areas of the world with poor sanitation have been infected with this virus. Hepatitis A infection does not cause chronic liver disease and is rarely fatal, but it can cause debilitating symptoms and acute liver failure, which is often fatal.The spread of hepatitis A can be reduced by adequate supplies of safe drinking water, proper disposal of sewage within communities, and personal hygiene practices (such as regular hand-washing with safe water).
