Answer:
AIDS (Acquired Immune Deficiency Syndrome) is the final and most serious stage of HIV disease, which causes severe damage to the immune system. The Centers for Disease Control has defined AIDS as beginning when a person with HIV infection has a CD4 cell (also called "t-cell", a type of immune cell) count below 200. It is also defined by numerous opportunistic infections and cancers that occur in the presence of HIV infection.
What Causes AIDS?
AIDS is the fifth leading cause of death among persons between ages 25 and 44 in the United States. About 47 million people worldwide have been infected with HIV since the start of the epidemic. The Human Immunodeficiency Virus (HIV) causes AIDS. 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 vaginal fluid, and breast milk. However, only blood, semen, vaginal secretions, and breast milk have been proven to transmit infection to others. Transmission of the virus occurs: Through sexual contact -- including oral, vaginal, and anal sex. Through blood -- via blood transfusions (now extremely rare in the U.S) or needle sharing. From mother to child -- a pregnant woman can passively transmit the virus to her fetus, or a nursing mother can transmit it to her baby. Other transmission methods are rare and include accidental needle injury, artificial insemination with donated semen, and through a donated organ.
