HIV particles (grey) covering a white blood cell.
HIV is thought to have entered into humans somewhere between 1914 and 1940.
In 1983, a retrovirus, now called human immunodeficiency virus (HIV), had been identified as the cause of AIDS.
The HIV antibody test has be used to screen all blood supplies in the U.S. since 1985.
People receiving blood or blood products before 1985 may have been infected.
The immune crippling disease caused by the HIV virus in which the body becomes unable to protect itself against any secondary infections.
HIV-Human Immunodeficiency Virus
HIV infects the immune system cell called the Helper T cells (-most important white blood cell involved in identifying infections.)
Semen/Vaginal fluids (as high as blood)
Pus from sores
It is highly unlikely you will be infected if you come into contact with:
Saliva (-highly possible if blood from mouth sores is present)
ANY type of sexual activity (highest risk)
Sharing used drug needles
Pregnancy-from mother to child
Sharing razors- if blood is present
Kissing- if even the smallest amount of blood is present. (-membranes of mouth are thin enough for HIV to enter straight into the body.)
Tattoos/body piercing if equipment is not clean.
How is HIV not spread?
NO! Drugs are available to manage the disease, but HIV stays in the body forever!
PROBLEM: RNA viruses mutate at a very high rate. A person with HIV under control can evolve resistance to the drug treatments.
Some infected persons have several strains of HIV in their bodies.
