Yes, but it is not likely. Compared to hepatitis B virus and the human immunodeficiency virus (HIV), it is less likely that you will spread the hepatitis C virus to your sex partner.

If you have one long-term sex partner, and one of you has hepatitis C and one of you does not, you do not need to change your sex habits at all. But, if either you or your partner is worried about the small chance of spreading the hepatitis C virus, you can use latex condoms. This will make it almost impossible to spread the virus. Long-term partners of people with hepatitis C should get tested for the virus. If the test is negative, you will probably not need to repeat it.

If you have more than one sex partner, you are more likely to spread the virus. In this case, reduce the number of sex partners you have, practice safer sex, and always use latex condoms.

There have been outbreaks of sexually transmitted HCV infection among men who have HIV and who have sex with men. It is recommended that men who have sex with men use condoms to reduce the risk of sexually transmitted HCV and other sexually transmitted infections.
