Hepatitis C is a virus that affects your liver. It can be very serious if it's not treated.
There are often no symptoms of hepatitis C at first. Some people get symptoms like muscle aches, a high temperature, tiredness and tummy pain.
You can catch hepatitis C from contact with the blood of an infected person, such as by sharing needles. It's very rare to catch it from having sex.
Hepatitis C can usually be treated with antiviral medicines. These need to be taken for several weeks.
You can reduce your risk of catching hepatitis C by not sharing needles, razors or toothbrushes with other people.
