Genital disease is most commonly caused by type II herpes virus, however, both groups also occur around the genitals.
In the vast majority of cases, blisters appear in groups within 3 to 20 days of infection, accompanied by a burning, itchy sensation, which become painful, epithelial-deficient, or ulcerated after a few days.
In women, they are most common on the vulva, but often spread to the vagina and cervix. Pain when urinating may indicate an infection that also affects the urethra. Once the symptoms have passed, the virus migrates to the ganglia, where it remains for a lifetime, so it can be transmitted asymptomatically. If the immune system weakens, it can cause symptoms again at any time.
