Human Papillomavirus, or HPV, is the most common sexually transmitted disease in the United States. More than 50% of sexually active people will contract genital HPV at some point in their lives, and some will never know due to the lack of symptoms of HPV. There are more than 40 types of this disease that can infect the genital areas, mouth, and throat. Being asymptomatic, many individuals infected with this virus are not aware they have an STD. Left undiagnosed, HPV can eventually cause a variety of cancers (like oral, cervical, and penile).
