    Abstract

    In case of a foot-and-mouth disease (FMD) or other exotic disease outbreak, surveillance zones and infected areas are conventionally created as circles with their centroids at the known infected premises. Given the availability of geographic information systems (GIS), it is no longer difficult to identify relevant zonal or area boundaries. However, it is not clear if from a disease control standpoint this is the optimal strategy. An alternative approach is to define regions using ZIP codes, counties, states, major roads, or natural barriers. We used an updated version of an epidemic simulation model originally applied to a 3-county area in California and the available information about the state’s livestock demographics to compare these two control strategies. The comparisons included the simulated duration of outbreaks, number of herds and animals affected, and manpower issues. These findings will be useful for state, national and international regulatory veterinarians in designing optimal disease control programs.
