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.

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

Some strains of genital HPV can cause genital warts, while others can cause cancer. Vaccines can help protect against certain strains of genital HPV.
