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 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. When HIV is left untreated, even a minor infection such as a cold can be much more severe.
Detailed explanation-3: -As HIV multiplies and destroys certain white blood cells-the CD4 cells, which fight bacteria and viruses-a person may develop symptoms of infection. These might include recurring fever, intense night sweats, and prolonged swelling of lymph glands in the armpits, groin, or neck.
