Genital warts are a common type of sexually transmitted disease (STD). Genital warts are soft, moist, or flesh-colored and appear in the genital area within weeks or months after infection. They sometimes appear in clusters that resemble cauliflower-like bumps and can be raised or flat, small, or large. This STD is caused by a virus called human papillomavirus (HPV). Although there is no known cure for HPV, there are treatments that can help control symptoms, such as medications and medical procedures. Even without treatment for genital warts, however, they often disappear on their own. There is no way to predict whether the warts will grow or disappear.
