In Canada,the periodic circulation of West Nile Virus(WNV)is difficult to predict and,beyond climatic factors,appears to be related to the migratory movements of infected birds from the southern United *** hypothesis has not yet been explored in a spatially distributed *** main objective of this work was to develop a spatially explicit dynamic model for the transmission of WNV in Canada,that allows us to explore non-climate related hypotheses associated with WNV transmission.A Cellular Automata(CA)approach for multiple hosts(birds and humans)is used for a test region in eastern Ontario,*** tool is designed to explore the role of host and vector spatial heterogeneity,host migration,and vector feeding *** developed a spatialized compartmental SEIRDS-SEI model for WNV transmission with a study region divided into 4 rectangular *** used 2010–2021 bird data from the eBird project and 2010–2019 mosquito data collected by Ontario Public Health to mimic bird and mosquito seasonal *** considered heterogeneous bird densities(high and low suitability areas)and homogeneous mosquito and human *** high suitability areas for birds,we identified 5 entry points for WNV-infected *** compared our simulations with pools of WNV-infected field collected *** and sensitivity analyses were performed using MATLAB *** results showed good correspondence between simulated and observed epidemics,supporting the validity of our model assumptions and *** analysis showed that a 5%increase or decrease in each parameter of our model except for the biting rate of bird by mosquito(c^(B,M)and mosquito natural mortality rate(d^(M)),had a very limited effect on the total number of cases(newly infected birds and humans),prevalence peak,or date of *** demonstrate the utility of the CA approach for studying WNV transmission in a heterogeneous landscape with multiple hosts.
