| Scientific title | Acceptance and cost effectiveness of insecticide treated curtains in areas with low Aedes infestation levels: a single-centre, cluster, randomised controlled trial |
| Study objectives | Acceptance, effectiveness and cost effectiveness of a dengue control intervention implementing insecticide treated curtains, as a single Aedes control strategy will be different than when implementation of curtains is combined with community based environmental management. |
| Ethics approval(s) | Ethical committee of University Hospital Antwerp, 15/09/2008 |
| Health condition(s) or problem(s) studied | Effect of intervention on Aedes aegypti infestation levels (vector of dengue fever) |
| Intervention | 1. Insecticide treated curtains: made from long-lasting, insecticide treated (pyrethroid deltamethrin is applied during manufacture) polyester netting that requires no re-impregnation, materials are special ultraviolet (UV) protected and retain their insecticidal properties and efficacy for about 2 years (information from producer). 2. The material has been approved by World Health Organisation Pesticide Evaluation Scheme (WHOPES) for use as bednets. 3. Community based environmental management approach: dengue control activities were identified, designed, planned and executed by the community itself, with the support of newly set up local 'community working groups' 4. Control: routine aedes control programme (entomological surveillance, source reduction, selective adulticiding and health education) |
| Intervention type | Other |
| Primary outcome measure | 1. Aedes infestation levels are the primary outcomes 1.1. House Indices (HI) - number of houses positive for at least one container with Aedes aegypti immature stages/100 inspected houses 1.2. Breteau Indices (BI) number of containers positive for Aedes. aegypti immature stages/100 inspected houses 1.3. Pupal Indices (PI) number of Aedes. aegypti pupae/inhabitant 2. In cycles of 11 days, the National Vector Control programme conduct routine entomological surveys in all dwellings of the municipality. This will provide the entomological information for all clusters for the period of study. |
| Secondary outcome measures | 1. Uptake, use and acceptance of Insecticide treated curtains 2. Financial cost of the two interventions in comparison to the control 3. The percentage of blocks repeatedly positive for larvae 4. Level of community participation based on Rifkin criteria |
