Actually , no one has documented where the first
aids transmission occured. One theory was that
the SIV (simian immunodeficiency virus) mutated in
a monkey, and some of the workers down in the jungle,
decided to have "bush meat" for lunch, and somehow, SIV
now mutated to HIV, survived the cooking, and the digestive
juices, and voila!
The best wat to prevent hiv and aids is to sit down and keep your mouth shut
