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.
HIV (human immunodeficiency virus) is a virus that attacks the immune system, the body's natural defense system. Without a strong immune system, the body has trouble fighting off disease. Both the virus and the infection it causes are called HIV. White blood cells are an important part of the immune system.HIV infects and destroys certain white blood cells called CD4+ cells.ithout a strong immune system, the body has trouble fighting off disease.
