Key facts about Hepatitis A
- It is an inflammation of the liver caused by the hepatitis A virus (HAV).
- The virus is primarily spread when an uninfected (and unvaccinated) person ingests food or water that is contaminated with the faeces of an infected person.
- Hepatitis can be an acute (short-term) infection or a chronic (long-term) infection.
- There are different types of hepatitis, with different causes:
- Viral hepatitis is the most common type. It is caused by one of several viruses — hepatitis viruses A, B, C, D, and E.
- Alcoholic hepatitis is caused by heavy alcohol use.
- Toxic hepatitis can be caused by certain poisons, chemicals, medicines, or supplements.
- Autoimmune hepatitis is a chronic type in which your body’s immune system attacks your liver. The cause is not known, but genetics and your environment may play a role.
- Hepatitis B, hepatitis C, and hepatitis D spread through contact with the blood of someone who has the disease.
- Hepatitis B and D may also spread through contact with other body fluids. This can happen in many ways, such as sharing drug needles or having unprotected sex.
- Symptoms: Some people with hepatitis do not have symptoms and do not know they are infected.
- Common symptoms include: fever, malaise, loss of appetite, diarrhoea, nausea, abdominal discomfort, dark-coloured urine and jaundice.
- Treatment: There is no specific treatment for hepatitis A. Recovery from symptoms following infection may be slow and can take several weeks or months.
