Now that the elimination of rabies in Western Europe is nearly complete, thanks to the oralmass vaccination of foxes (ORV) which took place over the last 25 years, it is necessary to prepare for emergency situations due to the re-introduction of rabies from still infected areas. Such emergency strategies should aim at minimizing the risk of falling back to large-scale vaccination, in a cost efficient manner. An approved spatially-explicit simulation model of spread and control of rabies was adapted to the new problem of re-introduction of rabies into free areas. The logic of the model and Options for local emergency vaccination (for example ring-vaccination vs. compact area treatment or heavily concentrated vs. thin extended control areas) were determined. Based on systematic simulation experiments the performance of strategic options was assessed. Key issues such as public health risk (i.e. number of rabies cases), failure risk (i.e. disease breakout from the control area), and budgetary risk (i.e. duration of the emergency program) were simultaneously considered. The results obtained reveal fficiency relations that contradict a priori derived management suggestions
