Effect of mosquito movement and spatial distribution on human infection attack rates.

The parameters summarized are the daily probability that an individual mosquito moves to a new location, the ratio of moves that are random vs. short range, the transmission probability per infectious bite from person to mosquito (), the transmission probability per infectious bite from mosquito to person (), the mean number of mosquitoes per location and the distribution, and the mean and standard deviation of the human dengue attack rate (AR). Three scenarios are highlighted and are illustrated in Figures 1B–D: a) is the default, which includes mostly short-range but some random (i.e., not restricted by distance) mosquito movement and a uniform distribution of mosquitoes, b) is the well-mixed model, with frequent random mosquito movement and a uniform distribution of mosquitoes, and c) has the same mosquito movement as the default but the number of mosquitoes per location is drawn from an exponential distribution. The infection attack rates are reported as the means and standard deviations from 40 stochastic runs.
