HIV (human immunodeficiency virus) is a virus that attacks cells that help the body fight infection, making a person more vulnerable to other infections and diseases. It is spread by contact with certain bodily fluids of a person with HIV, most commonly during unprotected sex (sex without a condom or HIV medicine to prevent or treat HIV), or through sharing injection drug equipment.
If left untreated, HIV can lead to the disease AIDS (acquired immunodeficiency syndrome).
The human body can’t get rid of HIV and no effective HIV cure exists. So, once you have HIV, you have it for life.
However, by taking HIV medicine (called antiretroviral therapy or ART), people with HIV can live long and healthy lives and prevent transmitting HIV to their sexual partners. In addition, there are effective methods to prevent getting HIV through sex or drug use, including pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP).
First identified in 1981, HIV is the cause of one of humanity’s deadliest and most persistent epidemics.
