Genital herpes can be contracted from infected bodily fluids, including semen, vaginal fluid, saliva or herpes lesions, sores or blister fluid. Genital herpes is transmitted through unprotected oral, vaginal or anal sex, or from skin-to-skin contact with an infected partner. Chances of transmitting genital herpes (whether HSV-1 or HSV-2) increase if there are open, active sores or lesions present. It is possible to contract genital herpes even if your partner does not show symptoms.
Genital herpes can only be prevented by abstaining from sexual activities. Latex or polyurethane condoms can help lower the risk of transmission for those who are sexually active, but because condoms do not cover all of the area that may be infected, genital HSV-1 and HSV-2 can still be contracted while using a condom.
