Simulation results for proportion of all Plasmodium falciparum (Pf) detected by radius. a Using month time steps, b using month time steps but including farm huts, c using week time steps instead of month time steps. At the month time step (a, b), 54% of the screenings would have occurred during months in which no case occurred, and at the week time step (c) 41% of the screenings would have occurred during weeks in which no cases occurred. The results depicted here are for the remaining 46% (for a, b) and 59% (c) of screenings during which it was possible to detect cases. The 5-m radius indicates screening only within the index house
