The Origins of an Epidemic: Turning HIV against Itself
In July 1981, The Center for Disease Control and Prevention, along with New York Times reported an abnormally large number of reports of a rare form of cancer, among gay men. The disease at that time was identified as Kaposi’s sarcoma (KS) and Pneumocystis Carnii Pneumonia (PCP). Kaposi’s sarcoma is to be known as a rare cancer that affected mainly older men of Mediterranean descent, was becoming increasingly high in many of the patients. The cancer appears as painless reddish-blue to brown skin lesions, soft or firm, most often on the legs, it may further spread into internal organs, especially the lungs and gastrointestinal tract over a period. Pneumocystis Carnii Pneumonia (PCP) is a microorganism that causes a disproportionate large percentage of all opportunistic infection in AIDS. PCP symptoms: fever, progressive shortness of breath, and a dry cough. KS and PCP also severely effect the immune system destroying white blood cells (CD4) level. KS and PCP leads to death in many of the patients and are neither curable nor preventable. This was the beginning of what has become the biggest healthcare concern in modern history. 25 years later society is still plague by HIV/AIDS.
What is the origin of HIV/AIDS? In 1959, our first HIV case arrived; a man died of a mysterious illness located in West Africa. The illness was unknown into recent years, when some plasma samples was taken from the man and examine; therefore; confirming that he did, in fact, die from complications related to a HIV infection, leading scientists to believe that the first case of HIV had arrived around 1930 in West Africa. One hypothesis is that a retrovirus related to HIV called simian immunodeficiency virus (SIV). SIV causes an AIDS-like illness in monkeys. It is possible that a retrovirus such as SIV was transmitted to humans but the disease did not produce itself in humans but later evolved into the pathogen HIV. This theory is supported by the existence of HIV-2, a virus similar to HIV that causes AIDS in western Africa. HIV-2 appears to be an intermediate form between HIV and SIV; it readily infects both humans, monkeys, and causes a less severe disease than HIV and SIV in their respective natural hosts. It may be that a strain of SIV entered humans from monkeys where it then evolved into HIV-2 and finally into HIV. HIV is properly named HIV-1 to distinguish it from HIV-2; however, it is usually called simply HIV because HIV-2 is rarely found outside of western Africa. One can imagine many different ways in which humans might contact non-humans primates to allow transmission of a virus: eating, hunting and trapping. Some observers have raised the possibility that polio vaccines produced nearly 20 years ago for use in Africa were contaminated with monkey retroviruses. They propose that the mass inoculation of this vaccine into humans introduced a virus able to reproduce in man and evolved into HIV. Proponents of this theory place the origin of HIV infection somewhere in central Africa.
How is the virus transmitted? Before scientists could clearly understand the transmission of the virus many people were, confused about the ways HIV could and could not be transmitted and conflicting reports from doctors made many sectors of the public somewhat distrustful of the medical professor. While the CDC maintained that HIV could be transferred only through bodily fluids such as blood and semen, some doctors openly express the belief that the virus could be transmitted through contact as casual as “sharing a bologna sandwich,” in the word’s of one observer. Another report stated that HIV could be excreted in tears. According to Dr. Anthony Faui, director of the National Institute of Allergy and Infections Diseases, “somehow that sprang a fear that it [HIV] must be all over the place.” (Bardhan-Quallen, 2003)
Parents kept their children out of school because they were afraid that their children would catch the disease even if those so-called, quote-unquote experts say it is impossible. There was discussing about quarantining HIV-infected individuals, or at least making it illegal for them, to engage in sexual activities. Scientists, who understood that many of the public’s fears were based in misconceptions, now struggled to find ways to prove that the fears were
