The control of Aedes aegypti for water access in households: Case studies towards a school-based education programme through the use of net covers.
AbstractWe report the progress made so far towards developing a school-based education programme for controlling Aedes aegypti oviposition in household flowerpots through the use of a net cover (evidengue®) to seal off the flowerpot saucer. A core feature of this programme is the association of evidengue® delivery with a basic package of oral and written information on dengue in classrooms. The flowerpot saucer is one of the most common type of water-bearing containers positive for the larvae of Ae. aegypti in the south-eastern region of Brazil. We present the results of a preliminary laboratory efficacy evaluation of evidengue® and of an inter-group, experimental, exploratory trial in which the evidengue® delivery was associated with educational information by means of a lecture and/or a leaflet in a school situated in a dengue-endemic area. The results are encouraging in both cases: (i) evidengue® has shown to be an efficacious tool to prevent ovipositing female access to flowerpot saucers in the laboratory; and (ii) despite the small numbers of students involved in the trial, one of the experimental groups yielded 85.7% of evidengue®-user households among those students whose households had flowerpot saucers. Use of evidengue® was maintained for at least 60 days, the period of data collection.
