Most people with genital herpes infection (HSV-2) don’t know they are infected. When symptoms are present, they often include blisters or sores in the genital area. Infected people can also have pain and burning when going to the bathroom. HSV-2 has a relative: HSV-1. Infection with HSV-1 causes cold sores and fever blisters, usually in and around the mouth. HSV-1 can also infect the genital area.
