Abstract

In Brazil, contagious diseases transmitted by vectors are a serious public health problem. In this work, it is investigated how the spatial distri bution of mosquitoes affects the spreading of diseases such as chikungunya. This investigation is based on a SIR-type model. The model is formulated in terms of a cellular automaton, in which each cell of the lattice corresponds to an individual of the host population. At each time step, each individual is in one of three states: susceptible (S), infected (I), or recovered (R). Four kinds of spatial distribution of mosquitoes are considered. The results of numerical simulations are discussed from an epidemiological point of view.
