Introduction
Hepatitis A is an infection of the liver caused by the hepatitis A virus. It is spread through contaminated water and food, especially shellfish or through person to person contact where personal hygiene is poor (faecal-oral route). There is also an association of hepatitis A amongst men who have sex with men (MSM).
Children, especially young children may be more likely to be exposed to hepatitis A during travel due to their natural exploratory nature and hand to mouth habits. Increasing age and being immune compromised are both risk factors for severe hepatitis A infection.
Hepatitis A occurs worldwide, mostly in countries where sanitation is poor. It is now rare in Western Europe, Scandinavia, North America, Japan, New Zealand and Australia. Most cases imported into Britain have been contracted in the Indian sub-continent.
