SIV to HIV

The theories I find most plausible are The Hunter Theory and The Contaminated Needle Theory. The Colonialism Theory relates to these. Being that HIV has been traced as far back as the 1930s, The Conspiracy Theory doesn't have much of a plausible base. Although I do find its content interesting. 

The Hunter Theory suggests that HIV was contracted by hunters eating and being exposed to chimps infected with SIV (simian immunodeficiency virus). The virus then adapted to its host's body when it was unable to fight it off and evolved into HIV-1. The evidence of different strains of HIV today would support this theory, since every time it was passed to the man it would develop in a slightly different way.

This then is extended into The Contaminated Needle Theory. When the use of disposable plastic syringes became customary and very widespread around the world as a cheap and sterile way to administer medication, people were taking advantage of the situation. However, with the huge amount needed it would have been far too expensive. They decided to completely throw out being sterile and would reuse needles without sterilizing in between use. So say a hunter came to get a vaccine or medication and was infected with SIV that had evolved into HIV-1. Anyone that had been injected with the same needle would then contract HIV-1 as well causing rapid infection in people all over the country and soon the world. This could have happened even if the SIV in the hunter hadn't converted to HIV yet. 

Another theory surrounding SIV evolving into HIV in humans is The Colonialism Theory. Basically people were being worked and kept in camps with very poor conditions like food scarcity, high physical demands, and little access to healthcare. This would have cause a weakened immune system in any person which would make it easy for SIV to infiltrate and convert to HIV-1. With the hiring of prostitutes to keep the workers happy, transmission was made easy for the virus and was very likely. Most of the workers died before developing AIDS due to the poor conditions, and so it was never noticed that people were infected with HIV.

I find The Conspiracy Theory interesting but not plausible. I mean after Tuskegee, how is the Black American population supposed to trust any thing monitored by the U.S. government. I am also somewhat offended that they think it is true. This is a bit off topic, but if we're supposed to be eliminating racism in today's world then there needs to be some trust. If they still think we are trying to secretly kill off their race and have them die horrible painful deaths then racism will never be eradicated. Yes, the things we are doing to keep racism alive need to come to a halt, however there won't be any respect for anyone of any race if no one can be the bigger man and forgive and forget. Trust is one of the keys to eliminating racism. 

Back on track, I believe it is very important to understand the origin of the virus. The more we know about a disease and where it came from, the more likely we are to find a cure or vaccine. We need to understand how HIV was transmitted to humans so that we can stop it from occurring.
