This puts you at risk for serious infections and certain cancers. AIDS stands for acquired immunodeficiency syndrome. It is the final stage of infection with HIV.
HIV is a virus that targets and alters the immune system, increasing the risk and impact of other infections and diseases. Without treatment, the infection might progress to an advanced stage called AIDS. The life expectancy of a person with HIV is now approaching that of someone who tests negative for the virus, provided that the person takes medications called antiretroviral therapy on an ongoing basis. These are types of T cell — white blood cells that circulate, detecting infections throughout the body and faults and anomalies in other cells. HIV targets and infiltrates CD4 cells, using them to create more copies of the virus. This increases the risk and impact of opportunistic infections and some types of cancer.

The virus attacks the immune system and leaves the body vulnerable to a variety of life-threatening illnesses and cancers. Common bacteria, yeast, parasites, and viruses that ordinarily do not cause serious disease in people with fully functional immune systems can cause fatal illnesses in people with AIDS. HIV has been found in saliva, tears, nervous system tissue, blood, semen including pre-seminal fluid, or "pre-cum" , vaginal fluid, and breast milk. However, only blood, semen, vaginal secretions, and breast milk have been proven to transmit infection to others.
HIV is spread primarily by unprotected sex including anal and oral sex , contaminated blood transfusions , hypodermic needles , and from mother to child during pregnancy , delivery, or breastfeeding.
