Abstract

This paper examines recent developments in migration studies. It reviews literature related to the potential role of internal population movement in the occurrence of schistosomiasis in Brazil and modifies Prothero’s typology of population movement for use in Brazil. This modified classification system may contribute to a better understand- ing of schistosome transmission as well as improved research and control programs. The results of this study indi- cate that population movement in Brazil primarily involves economically-motivated rural-urban and interregional movement. However, several movement patterns have become increasingly important in recent years as a result of changing socioeconomic and urbanisation dynamics. These patterns include urban-urban, intracity and urban- rural movement as well as the movement of environmental refugees and tourists. Little is known about the epidemio- logical significance of these patterns. This paper also highlights the role of social networks in the decision to migrate and to settle. Prothero’s classic population movement typology categorises movement as either one-way migrations or circulations and examines them along spatial and temporal scales. However, the typology must be modified as epidemiological information about new patterns becomes available. This paper identifies areas that require further research and offers recommendations that can improve the measurement and spatial analysis of the relationship between population movement and schistosomiasis.
