Hepatitis C: How common is sexual transmission?
How common is sexual transmission of hepatitis C?
- No name / No state given
Answer
Hepatitis C is transmitted primarily by exposure to blood containing the hepatitis C virus. Transmission rarely occurs from exposure to other infected body fluids, such as semen.
If you're in a long-term, monogamous relationship with a partner who has hepatitis C, your risk of sexual transmission is low — 0 percent to 0.6 percent a year. For monogamous couples, the Centers for Disease Control and Prevention (CDC) doesn't recommend routine condom use to prevent transmission. But couples should avoid sharing razors, toothbrushes and nail clippers.
The risk of transmission is slightly higher — about 1 percent a year — if you have multiple short-term sexual relationships with partners who have hepatitis C. This risk increases if a partner is also infected with HIV. Under these circumstances, the CDC recommends routine condom use to reduce your risk of transmission.
If you're concerned about hepatitis C, talk to your doctor. Hepatitis C can be diagnosed by a blood test. Treatment may include medications to help clear the virus from the bloodstream.
