Hepatitis A

Hepatitis A is an infection of the liver caused by the hepatitis A virus.


Hepatitis A occurs worldwide, mostly in countries where sanitation is poor. It is one of the most frequent causes of foodborne infections. It is now rare in Northern and Western Europe, North America, Japan, New Zealand and Australia. Most cases imported into Britain have been contracted in the Indian sub-continent. Outbreaks of hepatitis A infection can occur sporadically and can be explosive.
