Hepatitis A

Hepatitis A is caused by the hepatitis A virus (HAV). The virus is found in the stool (feces) of HAV-infected people. Hepatitis A can easily spread from one person to another by putting something in the mouth that has been contaminated with the stool of a person with hepatitis A.  It is spread more easily when sanitary conditions are poor or good personal hygiene is not observed.

The Hepatitis A virus is spread:

  • when someone ingests anything that's contaminated with HAV-infected stool (this makes it easy for the virus to spread in overcrowded, unsanitary living conditions)
  • in water, milk and foods, especially in shellfish
  • through close person-to-person contact

Because hepatitis A can be a mild infection, particularly in children, it's possible for some people to be unaware that they have had the illness. Although medical tests show that about 40% of urban Americans have had hepatitis A, only about 5% recall being sick.
