Pre-exposure Prophylaxis (PrEP) For Prevention of Human Immunodeficiency Virus: A Primary Practice Approach.

Acquired immunodeficiency syndrome (AIDS) is a chronic immune system disease caused by human immunodeficiency virus (HIV), first reported in 1981, and continues to interfere with the body's ability to fight infection and disease. There is no cure for HIV/AIDS, but medication can control infection and prevent disease progression. Pre-exposure prophylaxis (PrEP) taken orally, or as intramuscular injection, is safe and effective in reducing the chances of acquiring HIV.
