A<unk>  is a type of meshed curtain that is circumferentially draped over a bed or a sleeping area, to offer the sleeper barrier protection against bites and stings from<unk> s, flies, and other pest insects, and thus against the diseases they may carry. Examples of such preventable insect-borne diseases include malaria, dengue fever, yellow fever, zika virus, Chagas disease and various forms of encephalitis, including the West Nile virus. To be effective the mesh of a<unk>  must be fine enough to exclude such insects without obscuring visibility or ventilation to unacceptable levels. It is possible to increase the effectiveness of a<unk>  greatly by pretreating it with an appropriate insecticide or insect repellent. Research has shown<unk> s to be an extremely effective method of malaria prevention, averting approximately 663 million cases of malaria over the period 2000–2015.
