“…Our estimate of the cost of ACP was at the upper bound of annual cost p.h. reported previously, which ranged from US$0.60 in Cambodia, over US$1.89 in Thailand, US$2.14 in Philippines, US$2.19 in Venezuela, US$4.40 in Panama, and US$4.90 in Colombia, and up to US$31.74 in Kenya and US$31.75 in Mexico (16 ) (17) (25) (31 ) (32) (33) . The main cost drivers for the conventional control activities in Guantanamo were salaries, supplies for chemical control, and the cost for chemicals.…”

“…We were only able to compare our results regarding the cost of ITC implementation with estimates of ITC implementation from Venezuela (17) , Guatemala (18) , and Colombia (16) . Using a similar costing methodology, the costs p.h.in Guantanamo and Venezuela were found to be similar (US$7.50 vs. 6.95).…”

“…The classic vector control approaches to prevent dengue transmission require continuous costly efforts and have been shown to have insuffi cient effectiveness and sustainability (7) (8) (9) (10) . Recent reports about the potential effectiveness of novel tools, namely insecticide-treated curtains (ITC) and insecticide-treated jar covers, have been published (11) (12) (13) (14) (15) (16) . However, studies regarding the cost of ITC implementation are limited (16) (17) (18) .…”

However, studies regarding the cost of ITC implementation are limited (16) (17) (18) . In order to complement this limited evidence, we aimed to analyze the additional cost for implementing ITC in an environment with low Aedes infestation levels and an intensive well-structured Aedes vector control program, and the relationship between this cost and changes observed in entomological indices.…”

Introduction: Information regarding the cost of implementing insecticide-treated curtains (ITCs) is scarce. Therefore, we evaluated the ITC implementation cost, in addition to the costs of intensive conventional routine activities of the Aedes control program in the city of Guantanamo, Cuba. Methods: A cost-analysis study was conducted from the perspective of the Aedes control program, nested in an ITC effectiveness trial, during 2009-2010. Data for this study were obtained from bookkeeping records and activity registers of the Provincial Aedes Control Programme Unit and the account records of the ITC trial. Results: The annual cost of the routine Aedes control program activities was US$16.80 per household (p.h). Among 3,015 households, 6,714 ITCs were distributed. The total average cost per ITC distributed was US$3.42, and 74.3% of this cost was attributed to the cost of purchasing the ITCs. The annualized costs p.h. of ITC implementation was US$3.80. The additional annualized cost for deploying ITCs represented 19% and 48.4% of the total cost of the routine Aedes control and adult-stage Aedes control programs, respectively. The trial did not lead to further reductions in the already relatively low Aedes infestation levels. Conclusions: At current curtain prices, ITC deployment can hardly be considered an effi cient option in Guantanamo and other comparable environments.

“…En una intervención anterior en Girardot, departamento de Cundinamarca, considerada zona hiperendémica para el dengue en Colombia, se utilizaron cortinas y tapas elaboradas con tela de mosquitero impregnada con deltametrina de larga duración para cubrir los depósitos de agua con mayor producción de formas inmaduras de A. aegypti, y se encontró una reducción de 71 % en el índice de pupas por persona en las zonas de estudio, así como una buena aceptación de la intervención en la comunidad (11).…”

Introducción. El uso de mosquiteros tratados con insecticida en fórmulas de larga duración ha demostrado resultados prometedores en el control de Aedes aegypti.Objetivo. Evaluar la eficacia de mosquiteros impregnados con deltametrina en una fórmula de larga duración para el control de A. aegypti en Girardot, Colombia, después de tres lavados.Materiales y métodos. Se hicieron bioensayos de eficacia de los mosquiteros contra A. aegypti silvestres después de utilizar los siguientes tres productos de lavado, siguiendo la metodología de la Organización Mundial de la Salud: detergente en polvo, detergente en polvo y blanqueador, y jabón de barra, todos utilizados hasta en 20 lavados.Resultados. El tipo de producto de lavado y el número de lavados afectaron significativamente la eficacia de los mosquiteros impregnados con deltametrina. El lavado con jabón de barra presentó el mayor efecto, pues en tan solo seis lavados la mortalidad bajó a 50 % (25/50), en contraste con 66 % (33/50) de mortalidad después del lavado con detergente en polvo y de 84 % (42/50) después del lavado con detergente y blanqueador. En cuanto al número de lavados, el jabón en barra también causó una mayor reducción de la eficacia: a 68 % con solo tres lavados.Conclusión. La eficacia de los mosquiteros impregnados con deltametrina de larga duración en el control de A. aegypti varió con el tipo de producto de lavado y el número de lavados, siendo el jabón en barra el que redujo su eficacia en mayor medida. Se requieren nuevos estudios para establecer la disminución en la concentración del insecticida entre lavados.
