The STI Files: Human Immunodeficiency Virus (HIV)

HIV is a virus that destroys the immune system and thus weakens the body's ability to fight disease and infection, even common infections like flus and colds. HIV usually progresses to AIDS. This makes HIV the most dangerous sexually transmitted infection today. It is the fifth leading cause of death for the young under 40 in the United States. At this time, no one has been cured of HIV or AIDS.

Chlamydia is the most common bacterial infection (STI) in the United States, with about 3 million new cases reported annually. Chlamydia ("cla-mid-ee-ah") is so common in young women that, by age 30, 50% of sexually active women have evidence that they have had chlamydia at some time during their lives.
