Genital herpes is caused by Herpes Simplex Virus Type 2. But cold sores are cause by Herpes simplex virus type 1. Anyway, kisses and saliva exchange between affected and non-affected persons can cause spreading of infection. It can finally lead to infection in the genital area also. Antiviral treatment as prescribed by your doctor should be done and only after the healing of all scabs and ulcers, you should have skin to skin contact with affected people, to prevent spreading of infection. Hope my answer helps. Take care.
