Abstract
In this work, we describe a model to simulate the spread of withinand between- farms transmission of Classical swine fever virus (CSFV). It is a spatial hybrid model, based on the combination of a stochastic individual based model for between-farm spread with a Susceptible-Infected model for within- farm spread. An important characteristic of this model is the use, as an input, of the information available in real databases. The aim of this model is to quantify the magnitude, duration and risk zones of potential CSFV epidemics to provide support for the decision making process in future CSFV outbreaks. Model parameters and assumptions are provided and an illustration of the model’s results is performed by using available data from the Spanish region of Segovia. The outputs are also compared with those given by another model.
