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 is the virus that causes AIDS. AIDS is a series of opportunistic infections that occur when the immune system is weakened by the HIV virus.HIV is a blood-borne pathogen and is transmitted through the exchange of bodily fluids, specifically, blood and semen.he most common routes of transmission are unprotected sex with an infected person and exposure to infected blood and blood products, where the blood comes in contact with broken skin. There is no cure for HIV or AIDS, so prevention is the best course of action.
