Hepatitis C is an infection of the liver caused by the hepatitis C virus. You can get it from the blood of someone who has hepatitis C.
It can cause swelling and scarring of the liver and serious liver damage. It can also cause other health problems such as constant fatigue (extreme tiredness) and joint pains.
Hepatitis C is sometimes called a silent disease. This is because you might not realise you have it. You may not have any symptoms and feel OK. You may also have flu-like symptoms that can be mistaken for another illness.
There is no vaccine for hepatitis C, but there is a cure.
