what causes genital warts
Genital warts are a sexually transmitted infection (STI) caused by certain strains of the human papillomavirus (HPV). These skin growths can cause pain, discomfort, and itching. They are especially dangerous for women because some types of HPV can also cause cancer of the cervix and vulva.n HPV vaccine called Gardasil can protect men and women from the most common HPV strains that cause genital warts, and can also protect against strains of HPV that are linked to cervical cancer. A vaccine called Cervarix is also available.
