HIV Pre-Exposure Prophylaxis (PrEP)
Human immunodeficiency virus (HIV) attacks the immune system and makes it hard for the body to fight diseases and infections. HIV is passed (transmitted) through blood, semen, and fluids from the vagina and rectum.
HIV pre-exposure prophylaxis (PrEP) helps prevent HIV in people who have a very high risk of getting the virus. It is taken as a pill once a day.
