Forced movements of population and health hazards in tropical Africa.

Significant interactions between disease and population mobility have been demonstrated in tropical Africa in recent decades. Problems arising are greater than in the past. During the last two decades forced movements have become important. These are associated with refugees, coerced resettlement and victims of environmental catastrophe. The health hazards associated with them are reviewed from medical and social science literature for North East Africa (refugees and resettlement) and for West Africa (pastoralists affected by drought). Political, social and economic settings are of importance but tend to receive only limited attention. There is need for more social science input in studying and ameliorating problems arising from health hazards associated with and exacerbated by forced movements of population.
