- Primary Outcome Measures
Name Time Method <br> Standard larval indices for the Aedes aegypti mosquito:<br> 1. Breteau index: number of containers with immature stages per 100 houses<br> 2. House index: number of houses containing immature stages per 100 houses<br> 3. Container index: number of containers with immature stages per 100 containers with water<br> 4. Pupal surveys were also undertaken to calculate the number of pupae per person index (number of pupae collected/human population in a sector)<br><br> Follow up surveys were made to all houses at 3, 6, 9 and 12 months post-intervention. Analyses to measure impact of the intervention on dengue vector populations will be undertaken according to intention to treat and per protocol (based on coverage levels recorded in follow-up surveys).<br>
- Secondary Outcome Measures
Name Time Method <br> Interviews used to determine:<br> 1. Household characteristics<br> 2. Previous vector control intervention<br> 3. Better understanding of the local population's knowledge, attitudes and practice about previous methods of dengue prevention and control, and about ITMs for the same purpose<br> 4. Insecticide-susceptibility assays undertaken before and after intervention<br><br> Each house was also georeferenced with a handheld global positioning system receiver to permit subsequent overspill effects between adjacent treated and control clusters to be quantified.<br>
