Evaluation of control strategies

Epidemiological models can be used to compare the effect of various control strategies, for example by simulating a large number of outbreaks. Wageningen Bioveterinary Research has extensive experience with these computationally intensive methods that can be used to answer a wide range of questions. What is the needed 'vaccination radius' around an infected farm to effectively hold an epidemic in check? Is more effective control possible by making a distinction between animal species, farm type and region?

If simulation results are known down to the animal level, various screening scenarios can also be evaluated in order to declare the country free of disease following the outbreak. Additionally, the results can be used as input for economic analysis to compare the costs and benefits of control strategies.
