Hepatitis A is a serious disease of the liver that can cause death. It is caused by the hepatitis A virus (HAV), and is spread most often through infected food or water. Hepatitis A may also be spread by close person-to-person contact with infected persons (such as between persons living in the same household). Although some infected persons do not appear to be sick, they are still able to spread the virus to others.
Hepatitis A is less common in the U.S. and other areas of the world that have a higher level of sanitation and good water and sewage (waste) systems. However, it is a significant health problem in parts of the world that do not have such systems. If you are traveling to certain countries or remote (out-of-the-way) areas, hepatitis A vaccine will help protect you from hepatitis A disease.
