Unprotected skin-to-skin contact with an infected person is what causes HSV-2. Specifically, you can catch HSV-2 by touching:
- Herpes sores on the mouth or genitals
- Surfaces like the mouth, vagina, or anus (even if sores aren't visible)
- Saliva, semen, and vaginal discharge (even if the person isn't having an outbreak)
A person with a herpes diagnosis only sheds the virus from the body part that has the infection. Typically, this is the area where HSV-2 first entered the body.
Herpes HSV-2 can easily spread from person to person. The most common routes of transmission include:
- Genital-to-genital contact, which can occur during sexual intercourse
- Oral-to-oral contact when kissing
- Oral-to-genital or genital-to-oral contact during oral sex
- Skin-to-sore contact by touching an oral or genital sore
