Hepatitis A

Also called Hep A

Hepatitis A is a liver infection caused by a virus. It spreads through food or water contaminated with the poo of an infected person, and is more common in countries with poor sanitation. It does not usually cause long-term liver damage and most people recover fully within 2 months.

What it is

There is no specific treatment. Rest, fluids, pain relief and avoiding alcohol help the liver recover.

A vaccine is recommended for travel to some countries and for people at higher risk.

  • Flu-like symptoms
  • Tiredness
  • Feeling sick and loss of appetite
  • Pain in the upper right tummy
  • Yellow skin or eyes (jaundice)

How it is usually diagnosed
