Detailed explanation-1: -HIV (human immunodeficiency virus) is a virus that attacks the body’s immune system. If HIV is not treated, it can lead to AIDS (acquired immunodeficiency syndrome). There is currently no effective cure. Once people get HIV, they have it for life.
Detailed explanation-2: -HIV attacks a specific type of immune system cell in the body. It’s known as the CD4 helper cell or T cell. When HIV destroys this cell, it becomes harder for the body to fight off other infections.
Detailed explanation-3: -Infection with HIV is particularly troublesome for the immune system because it infects and destroys immune system cells called T helper lymphocytes or CD4+ T cells. Untreated, the disease progresses over a few years to AIDS, leading to eventual death for most people.
