Many diseases have strong roots in poverty. AIDS is actually one of them. Those who are poor end up doing drugs in order to escape the horrible conditions they live in. They often sell drugs too so they can make money which frequently leads to doing drugs too.
They have sex a lot too for lack of anything better to do. Those in poverty are usually not as informed as those who are better off, often because they can't read or write and information is not as accessible to them. All those things add up to being at a higher risk for AIDS. Other diseases, like Malaria, are very common in third world countries where there isn't money for prevention, be it vacines or even mosquito nets.
Tuberculosis is another disease that those in poverty are more apt to get. Again, for reasons of sanitation and for lack of funding for vaccination and lack of funding for the treatment that is necessary to help get rid of it and then others get it too and it can become a widespread disease.
