The Interaction between Seasonality and Pulsed Interventions against Malaria in Their Effects on the Reproduction Number
Figure 3
Effect size of repeated annual rounds of IRS in a non-seasonal setting.
The solid blue line is the true effect size calculated numerically. The line labelled “Using mean efficacy” is found by plugging the mean efficacy over the year into a reproduction number formula; and the line labelled “Using mean R” is found by plugging the efficacy at each time into a reproduction number formula, and then finding the mean over the year. A: Varying the repellency of the insecticide: lower repellency means greater lethality. B: Varying the coverage.
