Back in the 1980s, the global HIV and AIDS epidemic was one shrouded in stigma. By the time then-president Ronald Reagan gave his first address about AIDS, the epidemic had killed 20,849 people.
Approximately 35 million people around the world today live with HIV, the virus that causes AIDS, according to a 2013 report from UNAIDS, the United Nations project aimed at fighting the epidemic. The group estimates that 19 million of those infected do not even know they have the virus.
