The Crossing of Species
In my opinion, HIV was indefinitely passed to humans by the SIV virus found in simian species. There is scientific evidence and all results lead the this said conclusion. This theory is known as the hunter theory in which infected chimps were hunted, killed, and eaten by humans which evidently transferred the virus. This is the most plausible theory and is the one that I support. Two theories that I examined closer were the contaminated needle theory and th econspiracy theory. The contaminated theory model is that becuase of the cost of needles being too high, multiple injections were being made per needle to reduce cost. This theory is a little bit of a stretch to me. Organized medical programs would not look so much at the cost of buying needles in relation with the health of their patients. What this theory shows me is that this is a way that the virus could be spread in a very poor area where there is no regulated structure to the health care. At first, reading the conspiracy theory made me laugh. I though that this is something so stupid to even think. But than I remembered things like the radiation experiments and Tuskeegee. These were government administered tests on humans of challange. This is obviously not the case with HIV becuase it is proved that it derived from SIV but to read that interested me that the government creating a disease like this and administering it to humans is not something the our nation has not done in the past. If you compare these two theories, both of which are wrong to the origins of HIV, but both raise eyebrows of maybe. needles could not just start the epidemic, but they could absolutly increase the number of cases. The conspiracy theory actually is just ridiculous. But the needle theory is an example of just how easily the disease could spread which is very scary to think.

You make some excellent points here! I agree that the conspiracy theory is ridiculous, because even if there WERE a group out there malicious enough to want to fabricate a new virus for the sole purpose of causing harm to others, wouldn't they, having enough knowledge about viruses to be able to create a new one themselves, be intelligent enough to realize it could wind up hurting more than just those specific groups they wanted to target? And as for the OPV theory--this is only plausible if the virus already existed in human blood (and would therefore be, as you said, an explaination for how it could have been spread rather than how it could have originated). It will be interesting to see how many more theories come up before we finally discover the truth!
