The overall goal of the Southern Africa ICEMR is to make substantial contributions to regional malaria control measures that can be sustained in the long term. This goal will be achieved through a combination of:
In addition, the research team will collaborate with other ICEMRs in sub-Saharan Africa, Asia and South America.
The proposed research activities will provide detailed knowledge of malaria transmission, including epidemiology, vector biology and parasite population structure, to develop control strategies for the regional elimination of malaria.

With decreases in the incidence of malaria, wider catchment areas need to come under surveillance to detect transmission. The reactive surveillance approach has been proposed for this problem. In this strategy, neighborhoods of index malaria cases presenting at clinics and hospitals are visited to detect additional malaria infections. The rationale behind this approach is that malaria cases tend to cluster in space and time. The determination of the number of houses around the index case to visit tends to be arbitrary and could be improved using preliminary data on prevalence of malaria and population densities. The ICEMR working in Zambia and Zimbabwe has published a paper describing methods to adopt a more informed approach to design such a study using our ICEMR field sites in Zambia as a case study.
