From: West Nile virus transmission and human infection risk in Veneto (Italy): a modelling analysis
Model scheme. Model flow chart for WNV transmission in birds (squares) and mosquitoes (circles) in an average trapped area. Compartments: Bsa, Bea, Bia, Bra (Bsj, Bej, Bij, Brj): adult (juvenile) susceptible, exposed, infectious and immune birds; Ms, Me, Mi: susceptible, exposed and infectious mosquitoes. Parameters: λB and λM are the force of infection for birds and mosquitoes respectively and are computed as λB = b∙pMB∙Mi/BT and λM = b∙pBM∙(Bia + Bij)/BT, with BT being the total avian population and Ba the number of adult birds. See Table 1 for parameter values and references.
