Reflections on 40 Years of HIV - CDC MuseumJune 5, 2021 marked 40 years since the first official reporting, in CDC's Morbidity and Mortality Weekly Report (MMWR), of five cases describing what later became known as Acquired Immune Deficiency Syndrome (AIDS) and what is now HIV Stage III. On the 40th anniversary, the CDC remembered the more than 32 million people who have died from HIV worldwide since the start of the global epidemic, and the 38 million people currently living with HIV. Along with the global community, the CDC redoubled its efforts to ensure equitable access to services and prevention strategies, especially for those disproportionately affected by HIV, so that we may end the HIV epidemic in the U.S. and around the world.
