The World Health Organization is recommending the use of malaria bed nets treated with new insecticides in areas with parasite resistance.
Insecticide-treated bed nets are key tools for malaria prevention. Since 2005, over 2 billion of them have been distributed globally. But they have all been treated with one insecticide, pyrethroid. Mosquito resistance to this insecticide in a number of areas now poses a threat to malaria control efforts.
The new recommendations combine pyrethroid with an additional chemical to overcome any resistance.
