June 5, 1981 is the day most commonly recognized as the beginning of the AIDS pandemic.
On this date, the Centers for Disease Control and Prevention
reported five cases of a "rare form of pneumonia" in gay Los Angeles, California
residents. The new illness, named Human Immunodeficiency Virus or HIV
, weakened the immune system and could develop into it's most advanced state- AIDS or Acquired Immune Deficiency Syndrome.
Twenty-five years later, an international scientific team traced the origin of HIV
to wild chimpanzees in a remote area of Cameroon, Africa. There is still no cure for HIV or AIDS.
