How HIV Crossed into Humans

Out of all the theories, the two that I think are the most plausible are the “Hunter Theory” and the “Contaminated Needle Theory”. I picked these two theories because I was told of the Hunter Theory when I was little and it is very easy cut yourself when preparing monkeys and getting monkey blood on your cut and I know that sharing needle happened in the past and still happens today.
After comparing these two theories, I believe that the “Hunter Theory” is the most plausible method. It is most plausible because it simple and the most rational theory of the two. Usually hunters will skin and cook their catch because it is part of their hunt. When cutting up the animal it is very possible for something to accidentally cut himself. It doesn’t matter what size of the cut is because if it pierces the skin, then infected blood can easily get in.
It is very important to understand how the virus was transmitted to humans because knowing the origin of the virus will allow us to trace it back to where it first developed. We know that Monkey’s have SIV which is like their version of HIV. How did the Monkey’s get SIV? Did the monkey get SIV infected blood into their system? If they did, whose infected blood was it? Knowing the origin also allows us to isolate a certain region where it first developed.

  1. I feel the same way that you do when it comes to what is the most plausible explanation of how HIV was born. This is very plausible because you could see how interaction with wild animals, especially chimps, could really birth a new disease in humans that was never seen before. The only thing i would disagree about is how important it is to find out where the disease originated. I think our resources should all be put into finding a cure for HIV.

  2. I would have to agree with you, it is very plausible to cut your self after cutting up monkeys and having blood contact that way. Ya it is import to understand how the virus was transmitted to humans. By knowing the cause of the main cause, it will help us narrow down and have a better understanding of how the disease came about and why it is so deadly to humans and not to monkeys.
