In the African countries where HIV/AIDS is a big problem the economies have big problems. People that have it are usually young people, they lack the physical power and the concentration to be effective workers, or they can not work at all, and this affects the economy because the efficiency is very low or non existent from the people that have HIV/AIDS.
