 Permanent dual is a new delta-methyrinclophenopionet developed by Vestergaard-Saul to provide more options to malaria control programs. In a recent study, it was found to be more effective than other pyrofoid-based nets at killing mosquitoes and protecting people from bites. It is also non-inferior to a pyrofoid-clophenopionet that has been shown to improve public health outcomes. This article was authored by Thomas Seym, Boris Endombich, Marshal Begbo, and others.
