Human Immunodeficiency Virus (HIV), the Lentivirus (Retroviruses), that attacks, interferes and weakens the body’s immune system. It doesn’t cause any signs or symptoms in the beginning, but When it remains for a longer time in the human body, it causes a chronic and life-threatening medical condition known as Acquired Immunodeficiency Syndrome.
There is no complete cure of HIV but it is possible to slow down its progression, and arrest its harmful activities via certain medical interventions. It has been reported in the literature that it evolved from animals, Chimpanzees, to humans.
