ITNs as a malaria prevention tool

Insecticide treated nets (ITNs) are one of the most effective methods of preventing malaria in malaria-risk areas. The insecticides used for treating bed nets kill mosquitoes, as well as other insects, and they also repel mosquitoes, reducing the number entering the house to feed on the people inside. In addition, if high community coverage of ITNs is achieved, the numbers of mosquitoes, as well as their life span, will be reduced. When this happens, all members of the community are protected, regardless of whether or not they are using a bed net. To achieve such effects, high community coverage is required. The use of ITNs has repeatedly been shown to reduce the incidence of severe disease and mortality due to malaria in malaria-affected regions. ITNs can also have a beneficial effect on other insect pests, such as head lice, ticks, bedbugs and cockroaches.
