Hepatitis A

Hepatitis A, also called 'hep A' is a virus that causes inflammation or damage in the liver.

The hepatitis A virus is found in the faeces (poo) of people and is usually spread by close personal contact (including sexual contact).

Deaths from hepatitis A are rare, but some people get very sick.

Hepatitis A is a different virus to hepatitis B and hepatitis C.

Cause of hepatitis A

Hepatitis A is a viral infection and can be spread though poor hand washing and hygiene of an infected person or by eating or drinking contaminated food or water. Hepatitis A can also be transmitted through anal or oral sex with a person infected.

It is important to be careful when travelling overseas where hepatitis A is common.

Symptoms of hepatitis A

Symptoms usually begin around 4 weeks after exposure to the virus for older children and adults. They can include:

Some infected children may not show symptoms.

There is no special treatment for hepatitis A.
