Where did AIDS first originate?

It comes from America first! The initial discovery of AIDS can be traced back to the west coast of the United States in 198 1 year. Five gay men infected with rare pneumocystis carinii pneumonia were first reported in Los Angeles, USA. This disease used to occur only in people with immunosuppression. New similar cases occur constantly. Most of the patients are gay men, and all of them have unexplained low immune function, so they died of opportunistic infections or tumors.

1982, the disease was officially named "acquired immunodeficiency syndrome (AIDS)", which refers to the immunodeficiency caused by non-congenital reasons and a series of related clinical manifestations, and transliterated as "AIDS" in China.

In just a few years, the AIDS epidemic has spread from the first few cases to the United States and major countries in Europe and America.
