The presence of the Human Immunodeficiency Virus (HIV) is present in the human body through direct contact of a mucous membrane or the bloodstream with a bodily fluid containing HIV. The liquid could be blood, semen, vaginal fluid, or breast milk.

1. Exit
At this stage the virus out of the body of an infected person. Can occur through sexual intercourse, blood transfusion, contaminated hypodermic needles.
2. Survive
HIV can not survive long in the body. To be able to spread it to other people, HIV must be able to survive outside the body. Used medical equipment and blood touch HIV-positive patients, which is immersed in a 0.5 percent chlorine solution, will be able to kill the virus.
3. Sufficient
Also determines the amount of virus transmission. Viruses that bit will have no effect on transmission. You should not believe in the threat of toothpicks or needles with HIV in a public place. The virus is very little even dead, so it can not spread to others.
4. Enter
Phase enter the stage where the virus has entered the body through the bloodstream. This can occur through blood exchange mothers with their babies during pregnancy, sexual contact, breastfeeding, and non-sterile injecting equipment that has penetrated the skin. A person can be infected with HIV if the HIV-positive sexual partners, both heterosexual and homosexual or bisexual.
