In 1929 the human race was infected with HIV.
In Africa hunters would go out and look for food. They would find primates and animals that were easy to kill. The animals had the disease and when the hunter would go out and get cut on a branch, the blood from the recently killed primate and the blood transfers and infects the human race. A man named Nathan Wolf has been tracking the spread and has been trying to stop new branches of HIV. He has been working with the locals of Africa to make it so that the spread is not as bad.
I think that it is great that Nathan is doing this. Helping keep new viruses out of the human race. we will be have less chance of getting infected and dying young.
