It is hard to believe but HIV is actually a very fragile organism. If HIV is outside the body, its capsid disintegrates very quickly which instantly 'disarms' the virus. That is why infection is virtually impossible without direct blood-to-blood contact or through the mixing of body fluids containing the virus.his DNA then becomes part of the infected cell's genetic material. HIV is a 'slow' type of virus that falls into the category of lentiviruses. Lentiviruses are called slow viruses because they take a long time to cause damage to the body. See image 1.
Causes. HIV is a viral infection that can be transmitted through sexual contact, through blood or from mother to child during pregnancy, childbirth or breast-feeding.
