Genital warts are one of the most common types of sexually transmitted infections. Nearly all sexually active people will become infected with at least one type of human papillomavirus (HPV), the virus that causes genital warts, at some point during their lives. Women are somewhat more likely than men to develop genital warts.

As the name suggests, genital warts affect the moist tissues of the genital area. Genital warts may look like small, flesh-colored bumps or have a cauliflower-like appearance. In many cases, the warts are too small to be visible.

Like warts that appear elsewhere on your body, genital warts are caused by the human papillomavirus (HPV). Some strains of genital HPV can cause genital warts, while others can cause cancer. Vaccines can help protect against certain strains of genital HPV.
