Dengue infection density estimates of first two seasons in (a) \(s_1\) and (b) \(s_2\). The black circles indicate the reported dengue infected human population density and the red line indicates the estimated line. The fitted curve in (a) is obtained by taking the actual initial values at the beginning of the time period. The parameter value, \(a_1\) obtained for season 1 is 10.79. The fitted curve in (b) is obtained by taking the final values of the fitted curve in (a) as the initial values for season in (b). The parameter value, \(a_2\) obtained for season 2 is 2.13.
