Description At some point during the 1930s, an altered form of Simian Immunodeficiency Virus, or SIV, was transferred from a chimpanzee to a human hunter.
This most likely occurred in the Democratic Republic of Congo when hunters handled and consumed meat from hunted chimpanzees.
Those initially infected by the chimpanzees would spread the disease further, and a generation later, in 1959, a man in the Democratic Republic of Congo died due to AIDS-related complications.
Using blood plasma, researchers have determined that he was the first documented case of the disease in humans.
Flashing forward to the 1970s, the disease continued to spread throughout the world undetected.
It reached countries such as the United States and England, passing the radar of most medical professionals, and as a result, no research was performed during the decade.
By 1981, an extremely rare type of skin cancer, Kaposi's Sarcoma, became increasingly common among gay men in New York City and California.
This, coupled with high rates of pneumonia, led researchers to believe immunodeficiency was on the rise due to a disease.
By the end of 1981, 121 Americans had died as a result of the unknown disease, and the following year, the United States Centers for Disease Control and Prevention, or CDC, made initial predictions related to the disease.
They hypothesized that the immune deficiencies present in gay men was the result of an infection.
As a result, the phrase Acquired Immune Deficiency Syndrome, or AIDS, was coined.
They also learned that other groups, such as drug users and hemophiliacs, were at equally high risk of contracting the disease.
By 1983, the disease had reached five continents and was becoming more widespread in Europe.
Gay men who had visited the United States and individuals who had connections to Africa were especially at risk.
At this point, researchers began to investigate these ties.
The disease was finally discovered in 1984 by Luc Montagnier at France's Pasteur Institute.
Platforma de publicare independentă CreateSpace a fost un serviciu de autopublicare pentru autori independenți, cunoscut în primul rând pentru că îi ajută pe autori să publice și să distribuie cărți tipărite la cerere.
CreateSpace și-a schimbat serviciile la Kindle Direct Publishing (KDP).
CreateSpace și KDP fac ambele parte din platformele de autopublicare ale Amazon, iar autorii pot folosi KDP pentru a publica și distribui atât cărți electronice, cât și cărți tipărite.
Prin KDP, autorii își pot crea, publica și distribui cărțile la nivel global, ajungând la cititori prin rețeaua vastă a Amazon.
Dacă sunteți autor sau aspiră să publice o carte, poate doriți să explorați Kindle Direct Publishing (KDP) pentru nevoile dvs.
