Sleeping under insecticide-treated mosquito nets protects against malaria

Long-lasting insecticidal nets provide personal protection against mosquito bites. They can be used as protection for people most at risk of malaria, such as young children and pregnant women in high malaria transmission areas. The nets are effective for 2-3 years, depending on the model and conditions of use. Between 2000 and 2015, the proportion of children sleeping under an insecticide-treated net in sub-Saharan Africa increased from less than 2% to approximately 68%.
