The risk of hepatitis C from sex is low
It is extremely rare to spread hepatitis C (HCV) among sexually monogamous couples. But other sexual practices can increase your risk.
Having sexually transmitted diseases raises risk
Having any type of sexually transmitted disease increases your risk for hepatitis C, particularly if a person has HIV. About one-third of all Americans infected with HIV also have hepatitis C.
Don’t have sex with open sores on genitals
Having an open sore on the genitals also increases risk of hepatitis C transmission. If either you or your partner has an open sore, avoid sex or use a latex condom.
