Detailed explanation-1: -HIV finds the white blood cells, called CD4 cells. HIV gets inside the CD4 cell and makes copies of itself. Then, HIV kills the CD4 cell and the new HIV copies find other CD4 cells to get inside and start the cycle again. HIV kills immune system cells that help the body fight infections and diseases.

Detailed explanation-2: -HIV is the virus that causes AIDS. HIV weakens and slowly destroys the body’s immune system, leaving you vulnerable to life-threatening complications from an infection or certain cancers. As HIV and AIDS battle your immune system, your central nervous system is also affected.

Detailed explanation-3: -The primary target of HIV is the immune system itself, which is gradually destroyed. Viral replication actively continues following initial HIV infection, and the rate of CD4 lymphocyte destruction is progressive.

Detailed explanation-4: -Human immunodeficiency virus (HIV) HIV targets CD4+ T cells by binding to the CD4 molecule on the cell surface, as well as a chemokine coreceptor – usually CCR5 or CXCR4.
