25 Years of AIDS.

In June 1981, scientists in the United States reported the first clinical evidence of a disease that would later become known as acquired immunodeficiency syndrome or AIDS. Twenty-five years later, the AIDS epidemic has spread to every corner of the world. Around 40 million people today are living with HIV and over 25 million have died of the disease. But years of struggle to control the epidemic have also yielded a growing list of breakthroughs.
