Proportion of pregnant women, children under five and other vulnerable people sleeping under effective insecticide-treated mosquito nets
Insecticide-treated nets are nets for hanging over sleeping places, treated with an insecticide that repels, disables and kills mosquitoes coming into contact with them. Conventionally treated nets are effective if they have been retreated correctly within the last six months (or the last yea the case of some chemicals), not washed more than three times since the last treatment and without holes or tears. LLIN's are effective if they are not older, and have not been washed more often, than recommended by the manufacturer (commonly no more than 20 washes and no more than 3 years old) and are without large holes or tears. Nets should a be of a size and shape that allows them to be hung over the bedding used. Nets are only effective if they are hung correctly, in a way that does not allow gaps through which mosquitoes can enter.
