AIDS is one of the biggest health challenges faced by humanity, difficult to overcome only after Cancer. WHO classifies AIDS as a pandemic disease, which is a disease that spreads all over the world or a wider geographic area. Although the disease was detected in the year 1982, university studies show that its origins likely lie in Africa where the disease may have begun from bushmeat practice and rapidly spread owing to the many socioeconomic reasons during the colonial era. From polygamy to prostitution and usage of unsterilized needles being used to quell diseases like smallpox and malaria outbreaks led to the spread of the disease. In retrospect, scientists from the University Of Oxford and the University of Leuven in Belgium have found that reports by Belgian colonial doctors during the time reported symptoms that match those with AIDS.
The basis of AIDS lies in non-human primates, originating from two strands or varieties of HIV, namely HIV-1 transferred from chimps to gorillas, and HIV-2 transferred from Mangabey monkeys to humans. It began as a mutation and spread rapidly due to aforesaid prevalent factors.
In a nutshell, it was only in 1982 that the strain was identified, though the disease has been under observation since the late 19th and early 20th century.
