Spatial trypanosomosis management: from data-layers to decision making

The use of geographical information systems (GIS) in the management of Afri can animal trypanosomosis in sub-Saharan Africa offers potential in assisti ng decisions on allocation of resources, prioritization of control areas, a nd planning and management of field operations. Here, Guy Hendrickx and col leagues review approaches being used to develop reliable data-layers and to incorporate these data into GIS models. They argue that techniques should be further refined to produce more-detailed data layers and to include a dy namic element, a problem rarely addressed until now.
