Effect of mass PEV and ITN distribution on parasite prevalence. The fraction of individuals with slide-microscopy detectable parasitaemia for one scenario with sustained 80% ITN coverage plus four scenarios layering an additional PEV distribution with 50% (red and blue lines) or 90% (orange and teal lines) efficacy, each at 50% or 80% demographic coverage. Upper panel: Baseline EIR=150, An.arabiensis vectors take 50% of feeds indoors. Lower panel: Baseline EIR=15, An.arabiensis feeds exclusively outdoors.
