Resumo: Information on the cost of implementing residual insecticide treatment (RIT) for Aedes control is scarce. We evaluated the incremental cost on top of intensive conventional routine activities of the Aedes control programme (ACP) in the city of Santiago de Cuba, Cuba. We conducted the cost analysis study in 2011-2012, from the perspective of the ACP. Data sources were bookkeeping records, activity registers of the Provincial ACP Centre, and the accounts of an RIT implementation study in 21 clusters of on average 4 house blocks comprising 5,180 premises. The annual cost of the routine ACP activities was 19.66 US$ per household. RIT applications in rounds at 4 month-intervals covering, on average, 97.2% and using 8.5 g of delthametrine annually per household, cost 3.06 US$ per household per year. Delthametrine comprised 66.5% of this cost; the additional cost for deploying RIT comprised 15.6% of the total ACP routine cost and 27% of the cost related to routine adult stage Aedes control. The incremental cost of implementing RIT is high. It should be weighed against the incremental effect on the burden caused by the array of pathogens transmitted by Aedes. The cost could be reduced if the insecticide became cheaper, by limiting the number of yearly applications or by targeting transmission hot spots.
