Mosquito nets treated withinsecticides provide better and effective protection by keeping away mosquitoes as well as killing them.ITNs are now becoming one of the main methods for control of malaria vectors in India. ConventionalITNs must be treated once or twice a year, depending on the duration of the transmission season.LLINs are mosquito nets whose fibres have been impregnated with the insecticide, so that theinsecticidal effect is maintained through about 20 washes, and up to 3 - 5 years. It is expected thatLLINs will replace use of untreated and conventional ITNs in malaria control intervention in high-riskareas over the coming years.One bednet is expected to cover on average 2.5 persons and thus, for a given village the number of bednets required is usually equal to the total population divided by 2.5 or the number of householdsmultiplied by 2. In a targeted village, the required number of nets should be distributed in one singleoperation. However, if nets are not in sufficient supply, it can be considered to distribute one net perhousehold per year for two years. In addition to distribution to targeted high-risk villages, bed netsshould be given to pregnant women in high risk areas and to special groups such as children in tribalschools and hostels.Every effort is being made to make all fresh bednet supplies to be LLINs; however, the ITNs beingissued and those already distributed should continue to be utilized, with regular impregnation. Whileplanning for bednet distribution, the total availability of bednets, i.e. conventional ITNs plus LLINs, willbe considered; reimpregnation requirements of existing bednets will also be considered.Behaviour change communication (BCC) efforts will be required to maximize reimpregnation ofconventional bednets as well as to ensure utilization of ITNs/LLINs.
