How HIV/AIDS transfered from monkey to human?
There are several theories to this, and none of them are proven. The most commonly accepted theory is that of the ‘hunter’. In this scenario, SIVcpz (like HIV, but the S stands for Simian) was transferred to humans as a result of chimps being killed and eaten or their blood getting into cuts or wounds on the hunter. Normally the hunter’s body would have fought off SIV, but on a few occasions it adapted itself within its new human host and become HIV-1.
