Causes of hepatitis A

The hepatitis A virus may be acquired from human faeces, contaminated uncooked shellfish and raw vegetables, and sexual contact with an infected person.

The hepatitis A virus is found in the faeces of an infected person. It is usually acquired from hands that are soiled after using the toilet or changing a nappy, or by swallowing water or food that have been contaminated by human faeces.

Uncooked shellfish and raw vegetables contaminated by sewage can also be a route of infection.

In addition, sexual contact with an infected person is a recognised route of infection.
