Hepatitis A
Hepatitis A is a liver infection caused by a virus that's spread in the poo of an infected person. Hepatitis A can be unpleasant, but it's not usually serious and most people make a full recovery within a couple of months.
The symptoms of hepatitis A develop, on average, around four weeks after becoming infected and include tiredness, joint and muscle pain, and a mild fever.
