The hepatitis C virus causes inflammation of the liver and, if left untreated, can result in liver disease, liver failure and even death.
Because the liver can still function when it is damaged, infected people can be unaware they have the disease because they suffer no symptoms.
When symptoms do occur, they are often vague and can be easily mistaken for another condition. Symptoms include:
- flu-like symptoms including a high temperature
- feeling tired all the time
- problems with short-term memory
- stomach pains
- feeling or being sick
- loss of appetite
- abdominal pain
- itchy skin
- joint and muscle aches and pain
In England, the most common way people catch the infection is by sharing injectable drugs equipment - accounting for nine in every 10 cases.
Less commonly, people can get hepatitis C through sex or being exposed to infected body fluids.
