Acquired immunodeficiency syndrome (AIDS) facts
AIDS stands for "acquired immunodeficiency syndrome."
AIDS is an advanced stage of infection with the human immunodeficiency virus (HIV). HIV usually is spread from person to person through contact with infected sexual secretions or blood.
People with AIDS have weakened immune systems that make them vulnerable to selected conditions and infections.
For people infected with HIV, the risk of progression to AIDS increases with the number of years the person has been infected. The risk of progression to AIDS is decreased by using highly effective antiretroviral therapy (ART) regimens.
In people with AIDS, ART therapy improves the immune system and substantially increases life expectancy. Many patients who are treated with ART have near-normal life expectancies.
ART is a treatment that must be continued for life. It is not a cure.
It is possible for HIV to become resistant to some antiretroviral medications. The best way to prevent resistance is for the patient to take their ART as directed. If the patient wants to stop a drug because of side effects, he or she should call the physician immediately.
If a person is exposed to blood or potentially infectious fluids from a source patient with HIV, the exposed person can take medications to reduce the risk of getting HIV.
Research is under way to find a vaccine and cure for HIV.
