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/AIDS. HIV, or human immunodeficiency virus, is the virus that causes AIDS (Acquired Immunodeficiency Syndrome). HIV attacks the immune system by destroying CD4 positive (CD4+) T cells, a type of white blood cell that is vital to fighting off infection. The destruction of these cells leaves people living with HIV vulnerable to other infections, diseases and other complications.
