Detailed explanation-1: -HIV (Human Immunodeficiency Virus) is a virus that attacks the immune system. (The immune system fights infections and diseases in a person’s body.) Over time, HIV weakens a person’s immune system so it has a very hard time fighting diseases. HIV causes AIDS (Acquired Immune Deficiency Syndrome).
Detailed explanation-2: -HIV attacks and destroys helper T cells. The other group of lymphocytes are called B-lymphocytes or B cells. They mature in the bone marrow and gain the ability to recognize specific foreign invaders.
Detailed explanation-3: -CD4 cells (also known as CD4+ T cells) are white blood cells that fight infection. CD4 cell count is an indicator of immune function in patients living with HIV and one of the key determinants for the need of opportunistic infection (OI) prophylaxis.
