The natural transfer (hypothesis or theory), in reference to the HIV/AIDS pandemic, states that humans first received HIV by contact with primates,[1] presumably from a fight with a Chimpanzee during hunting or consumption of primate meat, and became contaminated with simian immunodeficiency virus (SIV). According to the 'Hunter Theory', the virus was transmitted from a chimpanzee to a human when a bushmeat hunter was bitten or cut while hunting or butchering an animal. The resulting exposure of the hunter to blood or other bodily fluids of the chimpanzee could have resulted in infection. A contrasting hypothesis regarded as disproven is the oral polio vaccine (OPV) AIDS hypothesis.
