HIV/AIDS

HIV/AIDS (HIV-1; retrovirus; CCR5/CXCR4 co-receptor) systematically depletes CD4+ T cells → immunodeficiency → AIDS-defining illnesses; ART (antiretrovirals, 6+ classes) suppresses viral load to undetectable; U=U (Undetectable = Untransmittable) prevents sexual transmission.

Also known as: HIV, human immunodeficiency virus, AIDS, acquired immunodeficiency syndrome, HIV-1, HIV-2, PLHIV, ART, antiretroviral therapy, HAART
