How did the AIDS epidemic begin?

The beginning of the AIDS epidemic was a gentle shift in the genetic material of the virus that allowed the virus to become zoonotic, which means that it could be transferred from animals to humans. During the period that has probably lasted for decades, the virus was repeatedly transmitted from the primates in Africa to humans and eventually established a support in the human population and began to spread beyond the African continent. Before scientists and doctors were able to combine all dots, AIDS epidemics spread to most of the world; Since 2007, more than 33 million people around the world have been infected with HIV, a virus that develops in AIDS. Obviously, the HIV virus came from the primates living in Western and Central Africa and that it was probably transmitted to people in comvěž, where people eat primates. Some scientists have suggested that the rise of cities in Africa can also contribute to the spread of AIDS by concentrating the human populations.

from Africa virus AIDS jumped on Haiti and then startsl quickly spread in different directions. A homosexual stewardess sometimes referred to as "Zero patient" is often defamed for causing AIDS epidemic, but all evidence suggests that the virus spreads at the same time in several communities; In fact, the HIV virus has several different groups or "Clades", illustrating the fact that it was not due to a single individual.

Clades also indicate something more interesting, which is that HIV and AIDS are probably much older than people think. General knowledge of AIDS epidemic suggests that the virus originated at the age of 80, but in fact it is probably Began spreading at the age of 30, growing exponentially as long as in the age of 20. At least one documented AIDS death dates back to the 1950s and supports this view.

learn more about spreading AIDS epidemic, scientists hope to discover new techniques of treatment and perhaps cure or vaccinatedagainst the disease. For example, different Clades respond in unique ways to treatment, illustrate the diversity of HIV and AIDS viruses, and some pins are fatal than others; Less fatal pins are probably older, because their victims would live long enough to spread the disease.
