Intercourse is NOT necessary. Symptoms Usually no symptoms, but external lesions may itch. Lesions on the skin can be either raised from the skin or flat. Lesions on the cervix can be seen with the use of magnification. Long term complications unknown.
Viral particles remain after treatment, but lesions can be eliminated.
It is doubted that the presence of these particles alone can result in transmission. Prevention Barrier methods are only partially protective. Lesions may not be present in areas not covered. Only total absence of touching of infected tissue will avoid transmission.
