SAN FRANCISCO (KGO) -- In the early 1980s, a mysterious disease began taking the lives of individuals, at first, mostly men who engaged in homosexual activity. Doctors noticed Kaposi's sarcoma and Pneumocystis pneumonia in mostly gay men, not just in San Francisco, but also major cities such as Los Angeles and New York City.
Medical experts eventually called it Acquired Immunodeficiency Syndrome or AIDS which is caused by HIV.

At the time, doctors later found out heterosexual individuals can also get HIV and AIDS not just through unprotected sex, but also through drugs.
Millions of people have passed away from AIDS.
