Hepatitis C [SEP] Sexual intercourse
Sexual transmission of hepatitis C is uncommon. Studies examining the risk of HCV transmission between heterosexual partners, when one is infected and the other is not, have found very low risks. Sexual practices that involve higher levels of trauma to the anogenital mucosa, such as anal penetrative sex, or that occur when there is a concurrent sexually transmitted infection, including HIV or genital ulceration, present greater risks. The United States Department of Veterans Affairs recommends condom use to prevent transmission in those with multiple partners, but not those in relationships that involve only a single partner.
