Aids stands for Acquired Immune Deficiency Syndrome.
Acquired means you can get infected with it.
Immune Deficiency means a weakness in the bodys system that fights diseases.
Syndrome means a group of health problems that make up a disease.
AIDS is caused by a virus called HIV, the Human Immunodeficiency Virus. If you get infected with HIV, your body will try to fight the infection. It will make “antibodies” — special molecules to fight HIV.
A blood test for HIV looks for these antibodies. If you have them in your blood, it means that you have HIV infection. People who have the HIV antibodies are called “HIV-Positive.” Fact Sheet 102 has more information on HIV testing.
Being HIV-positive, or having HIV disease, is not the same as having AIDS. Many people are HIV-positive but dont get sick for many years. As HIV disease continues, it slowly wears down the immune system. Viruses, parasites, fungi and bacteria that usually dont cause any problems can make you very sick if your immune system is damaged. These are called “opportunistic infections.” See Fact Sheet 500 for an overview of opportunistic infections.
How Do You Get AIDS?
You dont actually “get” AIDS. You might get infected with HIV, and later you might develop AIDS. You can get infected with HIV from anyone whos infected, even if they dont look sick and even if they havent tested HIV-positive yet. The blood, vaginal fluid, semen, and breast milk of people infected with HIV has enough of the virus in it to infect other people. Most people get the HIV virus by:
having sex with an infected person.
sharing a needle (shooting drugs) with someone whos infected
being born when their mother is infected, or drinking the breast milk of an infected woman.
Getting a transfusion of infected blood used to be a way people got AIDS, but now the blood supply is screened very carefully and the risk is extremely low.
There are no documented cases of HIV being transmitted by tears or saliva, but it is possible to be infected with HIV through oral sex or in rare cases through deep kissing, especially if you have open sores in your mouth or bleeding gums. For more information, see the following Fact Sheets:

The Centers for Disease Control and Prevention (CDC) estimates that 850,000 to 950,000 U.S. residents are living with HIV infection, one-quarter
