Detailed explanation-1: -AIDS (acquired immunodeficiency syndrome) is the most severe stage of HIV (Stage 3). People with AIDS have badly damaged immune systems. They get an increasing number of severe illnesses, called opportunistic infections (OIs). their CD4 cell count drops below 200 cells per milliliter of blood.
Detailed explanation-2: -Acquired immunodeficiency syndrome (AIDS) is a chronic, potentially life-threatening condition caused by the human immunodeficiency virus (HIV). By damaging your immune system, HIV interferes with your body’s ability to fight infection and disease.
Detailed explanation-3: -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-4: -HIV and AIDS are secondary immunodeficiency disorders because they develop from a virus, not a gene mutation. Other examples of secondary immune deficiencies may include a weakened immune system from chemotherapy drugs and malnutrition.
Detailed explanation-5: -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.
