An Insecticide-Treated Net (ITN) is a type of bed net that has been treated with insecticides to protect against insect bites, particularly from mosquitoes. These nets are commonly used in areas where diseases like malaria and dengue fever are prevalent. The insecticide helps to kill or repel insects, providing a barrier between the user and potential disease-carrying pests. ITNs are typically made from lightweight, durable materials and can be hung over beds or sleeping areas. Regular re-treatment with insecticide is necessary to maintain their effectiveness. Organizations like the World Health Organization promote the use of ITNs as a key strategy in reducing the incidence of mosquito-borne diseases.
