Costs of single-phase door-to-door insecticide-treated net mass distribution campaigns in Nigeria: a case study in Ondo and Anambra states

ITN campaign economic costs in this study were lower than most estimates from other African countries. While net procurement was the primary cost driver, the cost per year of effective protection was strongly influenced by ITN durability, highlighting the need for strategies that extend functional net lifespan. The findings provide essential inputs for cost-effectiveness analyses of campaign deployment of new generation nets when combined with epidemiological impact data.
