Recent large-scale field trials show that mosquito nets impregnated with insecticide can substantially reduce all-cause mortality in children in malaria-endemic areas in Africa. This paper considers the cost-effectiveness of impregnated nets, initially from the perspective of a government programme which would distribute nets free of charge and organize and fund re-impregnation on an annual basis. The calculations show that with the reductions in all-cause mortality observed in the trials, complete government subsidy of nets through a vertical programme would represent an efficient use of scarce resources for most combinations of assumptions. However, alternative ways of financing and organizing the use of impregnated nets are also possible and may be more cost-effective than vertical delivery. Distribution of nets and insecticide might be less costly than required for a vertical programme by integrating delivery with other types of government health programmes, with private sector delivery systems for other types of products, or with government systems developed for other sectors such as agriculture. Further, not all the costs need to be met by governments, as costs could be shared with donors, NGOs and the beneficiaries. The major conclusion is that impregnated nets would save a large number of lives in malaria endemic areas, they are an efficient use of scare resources, and ways of encouraging their use need to be developed and tested.
