Fig. 6: Estimates of dengue infections in cities and the relationship between population mobility and dengue infections.

(a–e) Estimates of the number of dengue infections in each city for each month and for the whole year. Redder colors in the cities indicate more severe infections, and the legends record the infections’ range of specific numbers. (f–j) Estimated infections due to population movement in each city and the network of population movement intensity between cities. Estimated infections attributed to population movement in each city, along with a network illustrating the intensity of population movement among cities. Dots represent infections in cities. The thickness of the blue line represents the intensity of population movement between cities. (k–o) Population outflows in five cities. The lines and dots indicate the location of the population outflow from the city. Larger pink dots indicate higher population outflows. Note that the South China Sea part in the figure k-o is consistent with the previous figure, which is not shown due to the limited space in the figure.
