Twenty years of HIV/AIDS

Twenty years of HIV/AIDS

In June 1981, scientists in the United States reported the first clinical evidence of a disease that would become known as Acquired Immunodeficiency Syndrome or AIDS. Twenty years later, the AIDS epidemic has spread to every corner of the world. Almost 22 million people have lost their lives to the disease and over 36 million people are today living with HIV, the virus that causes AIDS. But two decades of struggle to control the epidemic have also yielded a growing arsenal of breakthroughs.
