Hepatitis A is a disease of the liver caused bye the hepatitis A virus. There may be no symptoms; however the likelihood of symptoms increases with the person’s age. If symptoms are present, they include yellow skin or eyes, tiredness, stomach ache, loss of appetite, or nausea. Most often, hepatitis A is spread by the fecal-oral route (i.e., an object contaminated with the stool of a person with hepatitis A is put into another person’s mouth.) Less often, the disease is spread by swallowing food or water that contains the virus.
