The Do\u002DAble Dozen: Just a small increase in the use of insecticide\u002Dtreated mosquito nets could save 1.3 million lives this decade

on malaria, written by Rima Shretta and Randolph Ngwafor at the University of Oxford, proposes a 10 percentage-point scale-up in the use of bednets in the 29 highest-burden countries in Africa, alongside strategies against insecticide resistance, between now and the end of the UN’s 2030 promises.

to prevent malaria. Mosquitos are blocked by the netting and killed by the insecticide. Bednets each cost less than US$4 yet result in a dramatic reduction in transmission by ensuring mosquitos die before parasites can mature and spread.Article content It is important that bednets are not just distributed but are actually used correctly, which requires communication, information-sharing and changes in social behaviour. Even allowing for all this — as well as for the higher price tag of responding to resistant strains of malaria — the cost across this decade is about $1.1 billion a year. To put this into context, that is one-third of what the U.S. population spends onThis investment will save 30,000 lives even in 2023. By the end of the decade, the number of malaria deaths will be halved, saving some 1.3 million lives in total.Bednets also mean many fewer infections with malaria. The research shows that 242 million fewer people will get sick in 2030, drastically reducing health-care costs. Moreover, reducing the number of sick people means adults can go to work, children can go to school and caregivers are not stretched, which — at a country level — increases productivity. Putting all these factors together, every dollar spent on this campaign would yield societal benefits worth $48 — a phenomenal return on investment. We have allowed malaria to turn into a disease of poverty in Africa. While we cannot deliver on all the global UN promises, we can do the smartest things first. Distributing and using insecticide-treated bednets will cost little but save 1.3 million lives.is president of the Copenhagen Consensus and visiting fellow at Stanford University’s Hoover Institution.
