from how many years hiv (aids) is in earth?!
Question:
Answers:
In humans, they believe the first case to go back to the 1950s. One theory claims that HIV spread from primates to humans in Africa by people eating uncooked/undercooked primate meat.*
Three of the earliest known instances of HIV infection are as follows:
1. A plasma sample taken in 1959 from an adult male living in what is now the Democratic Republic of Congo.
2. HIV found in tissue samples from an American teenager who died in St. Louis in 1969.
3. HIV found in tissue samples from a Norwegian sailor who died around 1976.
*Diseases such as HIV spreading from animal to human is rare. Scientists speculate that this was possible only because of a mutated form of HIV in the primates.
