Bednet impregnation for Chagas disease control: a new perspective

Abstract

Summarybackground To determine the efficacy and acceptability of deltamethrin-impregnated bednets in controlling Chagas disease in South America.

Information to Act: Household Characteristics are Predictors of Domestic Infestation with the Chagas Vector Triatoma dimidiata in Central America

“…10 House improvement might be more appealing than other methods such as insecticide paints, which received low acceptance in communities in Honduras because of smells and secondary effects, 47 or bed nets, which were accepted by a population in Colombia but still require the introduction of foreign objects or practices. 48 House improvements should be complimented with peridomestic reservoir reduction because peridomestic triatominae foci can persist after house improvement. 24 A recent study in Guatemala showed good community acceptance of rodent control as part of an integrated vector management strategy.…”

Re-infestation of houses by Triatoma dimidiata after intra-domicile insecticide application in the Yucatán peninsula, Mexico

“…The prevention of dispersal of sylvatic/peridomestic adult bugs into domestic areas with door/window screens or bed nets may prove to be a simple, cost-effective and sustainable complementary or alternative strategy to reduce house infestation by triatomines in this region (Kroeger et al 1999). The usefulness of such a strategy may not be limited to the Yucatán peninsula, as the transient infestation of houses by flying sylvatic adult bugs is thought to be responsible for a significant transmission of Chagas disease in several other regions (Coura et al 1994(Coura et al , 1999(Coura et al , 2002.…”

Emerging Chagas Disease: Trophic Network and Cycle of Transmission ofTrypanosoma cruzifrom Palm Trees in the Amazon

“…An entomologic and epidemiologic system for surveillance of Chagas disease in Amazonia has been suggested (68,69). Alternatively, the enormous task of controlling emerging Chagas disease in the Amazon Basin should rely initially on an information, education, and communication program, which encourages control measures by the householder (e.g., use of screens, bed nets, insecticide-treated fabrics, and vegetation management) (69)(70)(71)(72)(73). Such a program for prevention of contact with triatomines should be conducted directly in communities, elementary schools, and churches and social clubs, reinforced by social marketing and mass media communications.…”
