I tested positive for hsv-1. how do i tell if i have an hsv-1 genital or oral infection?

Location of sores: You probably tested positive for hsv1 through a blood test. This will not tell you where or when you first contracted the virus. Most cases of hsv1 are simply due to fever blisters or cold sores from childhood. A smaller percent of patients will have hsv1 infection in the genital area. Most hsv2 infections are initially in the genital area. Both types can be in either area however.
