Bed nets treated with insecticide can reduce the transmission of Wuchereria bancrofti, the nematode that causes lymphatic filariasis, a debilitating tropical disease commonly known as elephantiasis, report an international team of scientists (Reimer LJ et al. N Engl J Med. 2013;369:745-753).
The researchers measured the transmission of W bancrofti, which is spread by the bite of the anopheles mosquito, among residents living in 5 villages in Papua New Guinea. The participants had previously received drugs that nearly eliminated the parasite from humans but did not prevent its transmission by the mosquito vector.
