Can you spread hep c through sex?

Low likelihood. Someone in a long-term, monogamous relationship with a partner infected with HCV is at low risk, the risk of sexual transmission ranges from 0 to 0.6 percent per year. This risk of transmission is slightly higher — about 1 percent per year — if involved in a short-term sexual relationship with someone who has Hepatitis C. The risk increases if the person is HIV positive.
