Hepatitis A: guidance, data and analysis

The symptoms, diagnosis, management and epidemiology of hepatitis A.

Hepatitis A virus infection causes a range of illness from mild, like non specific nausea and vomiting, through to hepatitis (liver inflammation, jaundice, or icterus) and rarely liver failure.

It is normally spread by the faecal-oral route but can also be spread occasionally through blood.

Good hygiene including safe drinking water and food handling and good handwashing practice prevents infection.
