Figure 8From: 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 \(\lambda = 1.3699\times 10^{-3}\) which corresponds to two years of cross immunity after primary experience infectionBack to article page
