The scaling up of Insecticide Treated Nets (ITNs), particularly Long Lasting Insecticidal Nets (LLINs) and the expansion of Indoor Residual Spraying (IRS) has contributed to a significant decrease of malaria worldwide. However, these control methods tackle only indoor and night biting vectors. The proportion of malaria transmission occurring before sleeping hours and outdoors („residual. transmission) is steadily increasing and compromises the efforts towards malaria elimination. Outdoor and early biting malaria vectors are of particular importance in Southeast Asia and present a major challenge in eliminating malaria and especially artemisinin resistant malaria at the Thai-Cambodian border. This anthropological study takes place within a multidisciplinary project which aims to raise evidence on the effectiveness of mass use of topical mosquito repellents in addition to insecticide impregnated bed nets in controlling malaria infections in the Northeastern highlands of Cambodia. By combining epidemiological, entomological and anthropological data, the project will collect information on the most important factors for successful reduction of „residual transmission.. The main objective of the anthropological study is to assess the acceptability, the adherence and the use of the topical repellents in addition to the nationally distributed LLINs.
