The hourly indoor and outdoor profile of human contact with malaria vectors in Ratanakiri province, Cambodia based on entomological data collected during 2009–2011 and human behaviour data collected during 2012–2013. The stacked line graph presents estimates of accumulated indoor and outdoor human contact rates with the four most common malaria vectors collected in the study area (Anopheles dirus s.l., Anopheles minimus s.l., Anopheles maculatus s.l., and Anopheles barbirostris s.l.). The movement pattern of people was taken into account by weighting the vector biting rates throughout the night by the proportion of humans that are typically indoors or outdoors at each time period. (A) No weighting by use of vector control tools; (B) Weighting by observed use of vector control tools.
