Combined impact of vector control and effective parasite clearance (measured as proportion of parasitological cure [PPC]) on years to reduce seroprevalence in children under 5 to <2%. Annual vector control defines the proportion by which vector density is reduced (0–100%); annual PPC defines the proportion of humans effectively treated, ie, the percentage of the infected human population achieving parasitological cure (0–40%). The color scale corresponds to number of years to achieve the serological criterion. The panels represent: A: low; B: moderate; C: high; D: very high endemicity levels (see Supplementary Materials).
