Wouldn't natural immunity be a force of evolution working here? Just like when brown/black bears started living in the polar regions their coats would change to a white/lighter shade to blend in with surroundings giving the bears a better chance of living, survival of the fittest. How are the workers evolving, they are resistant to the AIDS/HIV virus and giving these workers a better chance to survive in the area.
