What are the symptoms of Hepatitis A?

Three of every four persons infected with Hepatitis A virus have symptoms. When symptoms are present, they usually develop suddenly and may include fever, tiredness, loss of appetite, nausea, abdominal pain, dark urine, and yellowing of the skin and eyeballs. Adults have symptoms more often than children.

A person is most infectious about one week before symptoms appear and during the first week of symptoms. However, an infected person who has no symptoms can still spread the virus. Unlike some other forms of viral hepatitis, Hepatitis A causes no long-term damage and is usually not fatal.
