Insecticide resistance threatens malaria fight | Fox News

A study published last year found that mosquitoes in one region of Senegal swiftly developed resistance to bednets treated with deltamethrin, a pyrethroid.

WHO director general Margaret Chan said the levels of resistance found in Africa and India were of greatest concern.

“These countries are characterized by high levels of malaria transmission and widespread reports of resistance,” she said in a statement. In some places there was resistance to all four classes of insecticide.

The WHO plan says each country at risk must analyze the extent of resistance and design a pre-emptive management strategy as part of its national malaria control effort, rather than waiting for resistance to increase.
