Cost-Effectiveness of Social Marketing of Insecticide-Treated Nets for Malaria Control in the United Republic of Tanzania

Objective To assess the costs and consequences of a social marketing approach to malaria control in children by means of insecticidetreated nets in two rural districts of the United Republic of Tanzania, compared with no net use. Methods Project cost data were collected prospectively from accounting records. Community effectiveness was estimated on the basis of a nested case–control study and a cross-sectional cluster sample survey. Findings The social marketing approach to the distribution of insecticide-treated nets was estimated to cost US$ 1560 per death averted and US$ 57 per disability-adjusted life year averted. These figures fell to US$ 1018 and US$ 37, respectively, when the costs and consequences of untreated nets were taken into account. Conclusion The social marketing of insecticide-treated nets is an attractive intervention for preventing childhood deaths from malaria.
