Genital warts

Your Genital warts Guide

Genital warts have been described since ancient times. The viruses that cause the warts are varieties of the human papillomavirus (HPV). These viruses have an incubation period (interval between exposure to infection and appearance of the first symptom) of one to eight months. The infectivity (risk of infecting others) is highest soon after development of the lesion. Transmission is usually sexual, with more than 50% of contacts being affected. Their appearance around the anus may be related to anal intercourse, but not necessarily. The entire lower genital tract is usually involved, although it may be without obvious symptoms.
