In the early 1980s, many gay men were discovered to be suffering from Kaposi's sarcoma, a cancer usually associated with older men of Mediterranean ethnicity. Eventually gay men wasted away and died. Word began to spread throughout the gay community that gay men were dying of an otherwise rare cancer. The medical community began referring to this syndrome with the colloquialism "Gay Cancer." During research by medical scientists, they found that the syndrome included other manifestations, such as Pneumocystis carinii pneumonia (PCP). A rare form of pneumonia caused by protozoa, its name has been changed to "GRID", or Gay Related Immune Deficiency. The effect that the stigma of homosexuality has had on the general public's perception and management of the disease cannot be overlooked. Within the medical community, it quickly became apparent that the disease was not specific to gay men (such as transfusion patients, heroin users, heterosexuals). women and infants were added to the list of affected people), and the renamed syndrome (Acquired Immunodeficiency Syndrome) incorrectly claims that the disease was introduced by a gay male flight attendant, named Gaetan Dugas, referred to as "Patient Zero" . However, subsequent research revealed that cases of AIDS occurred much earlier than initially known. It was also theorized that a series of hepatitis vaccinations given in San Francisco's gay community were contaminated with HIV. There is a high correlation between those who received the vaccination and first cases of AIDS, although of course this has never been proven to be accurate. Since the turn of the century, the overall health of all Americans has improved substantially. Although advances in medical and scientific technology have improved the health status of the American people, there is growing concern and awareness that African Americans have not benefited equally from the fruits of science. While these facts are not “new news,” it is evident that most of the public and the scientific community are not fully aware of the full impact of these issues. There are government agencies that aim to provide health services to minorities: the Office of Minority Health (which seeks to develop health policies beneficial to minorities) and the National Center on Minority Health and Health Disparities (which seeks to promote minority health and eliminate health disparities). President George W. Bush spoke at a press conference in Philadelphia, Pennsylvania on June 23, 2004, where he announced his latest HIV/AIDS initiative.
