Geography Explains Why AIDS Levels Low in West Africa, Epidemic in East
Researchers at the University of Florida led the team that solved the mystery. The situation is this: infection rates of those with the viruses that cause AIDS held steady at relatively low levels for more than 50 years in west central Africa but jumped up to an epidemic in east Africa in the 1970s.
The explanation:
Essentially, the explanation for the HIV explosion — obscured until now — involves the relative ease with which people can travel from city to city in east Africa as opposed to the difficulties faced by people living in the population centers of the Democratic Republic of Congo, the point where HIV emerged from west central Africa in its spread to the east.
