Figure 7From: Mathematical evaluation of the role of cross immunity and nonlinear incidence rate on the transmission dynamics of two dengue serotypesTime series plots of the number of infected humans and mosquitoes predicted by the multi-serotype dengue model (2.4)–(2.5) with different initial sizes of the sub-populations. The values of model parameters used are given in Table 2 and \(\lambda = 0.0111\) which corresponds to cross immunity lasting as long as three months after primary experience infectionBack to article page
