What is the mechanism by which the AIDS virus causes deficiency of immune system of the infected person?


AIDS (Acquired Immuno Deficiency Syndrome) is caused by the Human immuno-deficiency virus (HIV).  The HIV virus enters the human body by various methods like sharing infected needles, unprotected sexual contact with infected person, or infected blood transfusion. After entering the virus attacks and enters the macrophages. Inside the macrophages, the RNA of the virus is used to produce viral DNA by the process of reverse transcription. The viral DNA integrates itself into the host DNA and directs the synthesis of virus particles. Simultaneously the  HIV enters helper T- lymphocytes and replicates to produce viral progeny there. The cell ruptures and releases newly formed progeny viruses into the blood, attacking other healthy helper T-lymphocytes in the body. As a result, the number of T-lymphocytes in the body of an infected person decreases progressively, thereby decreasing the immunity of a person.
