About 15% of hepatitis C infections are transmitted through sexual intercourse. Sexual transmission of hepatitis C is not as common as transmission of hepatitis B through this route. However, high-risk sexual behavior is associated with increased risk of getting hepatitis C. Risk factors for sexual transmission of hepatitis C include:
- Multiple sex partners
- Prostitute use
- Traumatic sex (inadequate vaginal lubrication may increase the risk of exposure to infected blood)
- Sexual intercourse during menstruation
Among married couples, the risk of transmission increases with the duration of the marriage. It is not known whether transmission occurs through sexual intercourse or the sharing of household items (eg, toothbrushes, razors, etc.).
If you have had a sexual relationship with anyone who has any of the risk factors for hepatitis C infection, you may want to get tested for hepatitis C too.
