Who Is Affected by Hepatitis C?
It is not always clear how a person becomes infected with hepatitis C. But it is estimated that:1
- Most people who get hepatitis C have been repeatedly exposed to infected blood. People at high risk include injection drug users, people who have dialysis regularly, people with hemophilia who were treated with blood clotting factors before 1987, and people who received blood transfusions before 1992.
- Between 10 and 20 out of 100 people who have received hemodialysis for kidney problems are infected with hepatitis C.
- About 1 out of 100 people, such as health care workers, become infected through accidental exposure to infected blood.
- Hepatitis C can be spread through sexual intercourse, but this happens only rarely. Hepatitis C is more likely to spread through sex among people who are also infected with HIV.
