Field observations of village-level human biting rates (B), sporozoite prevalence (S) and entomological inoculation rate (EIR) . and are plotted as a function of recent (October 2001–September 2003) and historical (early to mid 1990's with reported bednet use rates approximating zero). Note that B and EIR reflect community-level means values for non-users of bednets and recent values of S can only be reported as an overall mean for the entire study area. Open circles: Individual villages included in recent surveys, filled circles: mean of all villages historically or recently. For ., expected trends based on simulation modelling is presented as continuous lines for bednets which confer 19, 36, 64 and 96 % protection against indoor exposure (See methods).
