One of the reasons that HIV (human immunodeficiency virus) is so dangerous is because it attacks the body’s own immune system. As the virus replicates, it attacks immune cells that help the body fight off illnesses. 

Today’s HIV medications can prevent and reduce this damage to the immune system. The medicine used to treat HIV is called antiretroviral therapy, or ART.
