HIV-1 is the more commonly associated with AIDS in the US and worldwide, HIV-2 is more rare, and typically restricted to areas in western Africa and southern Asia. HIV-2 is so uncommon that “HIV” almost always refers to HIV-1. Alright HIV targets CD4+ cells, meaning cells that have this specific molecule called CD4 on their membrane.
The management of HIV/AIDS typically involves the use of multiple antiretroviral drugs. In many parts of the world, HIV has become a chronic condition, with progression to AIDS increasingly rare. HIV latency and the resulting viral reservoir in CD4 + T cells, dendritic cells, and macrophages is the main barrier to eradication of the virus. [19 ...

Although most cases of HIV/AIDS were discovered in gay men, on January 7, 1983, the CDC reported cases of AIDS in female sexual partners of males with AIDS. [42] In 1984, scientists identified the virus that causes AIDS, which was first named after the T-cells affected by the strain and is now called HIV or human immunodeficiency virus. [43]
