Two types of herpes simplex virus infections can cause genital herpes:
- HSV-1. This is the type that usually causes cold sores or fever blisters around your mouth, though it can be spread to your genital area during oral sex.
- HSV-2. This is the type that commonly causes genital herpes. The virus spreads through sexual contact and skin-to-skin contact. HSV-2 is very common and highly contagious, whether or not you have an open sore.
Because the virus dies quickly outside of the body, it's nearly impossible to get the infection through contact with toilets, towels or other objects used by an infected person.
