Five of the 10 most commonly reported infectious diseases in the United States are sexually transmitted diseases (STDs); in 1995, STDs accounted for 87 percent of cases reported among those 10.
An estimated 45 million persons in the United States are infected with genital herpes, and 1 million new cases occur per year.
Chlamydia and gonorrhea infections account for 15 percent of cases of infertility among U.S. women.
Four subtypes of human papillomavirus (HPV), a sexually transmissible virus that causes genital warts, are responsible for an estimated 93 percent of cervical cancer cases, with an estimated 5.5 million new cervical cancer cases occurring per year.
An estimated 800,000 to 900,000 persons are living with HIV in the United States, with approximately 40,000 new HIV infections occurring every year. An estimated one-third of infected Americans have not been tested and are unaware of their status.
