A new class of bed net that includes the chemical piperonyl butoxide (PBO) has been shown to significantly reduce malaria infection in children at one site in Tanzania, according to new research published today in The Lancet. WHO recommendations on pyrethroid-PBO nets were revised in late 2017 based on the results of this study, among others.
