HSV-1 is the type of herpes that usually causes oral herpes (cold sores). It can also cause genital herpes in some cases when it is transmitted from the mouth of one person to the genitals of another person during oral sex.
HSV-2 is the virus that causes most cases of genital herpes. Both viruses are transmitted when an uninfected person comes in contact with a sore on an infected person’s mouth, genitals, or mucosal surface or when they come in contact when an infected person’s skin is shedding the virus even if they don’t have an active sore.
