Hepatitis A is an infection of the liver caused by the Hepatitis A virus. The Hepatitis A virus is usually transmitted from faecal-oral contact route through person to person spread or contaminated food or drink.

Tests and treatment

Hepatitis A is diagnosed through specific blood tests. The incubation period (the time it takes from coming into contact with the virus to developing infection) is between 15-50 days, so tests may need to be repeated over a period of time.


A vaccination is available to protect against hepatitis A. This is available for people who have a higher risk of coming in to contact with the virus.
