Nonetheless, weak correlation between the meteorological parameters (T max , T min and h) and the population density (ρ) do exist. In view of this, we fitted the data points in each panel in Figure 5 with a linear relation, α = A + B × x and with a polynomial relation α = A + B × x + C × x 2 , with x as T max , T min , h or ρ. The best fit curves are shown by blue and red solid lines in Figure 5(a)-(d) , respectively. The degree of correlation (R 2 ), as obtained from the fitting procedures in each panel is shown in Table 1 . We find a weak correlation between the value of α and the parameters x. The value of R 2 is relatively higher if one assumes polynomial relations between the slope (α) and T max , ρ than if we consider a linear relation. In the fitting procedure, the data point for Maharashtra (shown by green symbol in each plot) is not included, as it lies much away from other data points. the author/funder, who has granted medRxiv a license to display the preprint in perpetuity.
