Abstract [en]

Background: It is estimated 3.9 billion people are at risk of being infected with dengue, which poses a threat to public health and creates an economic burden to resource constrained countries. The primary prevention strategy for dengue is vector control aiming to reduce mosquito population and human-vector contacts. WHO is promoting integrated vector management as a rational decision making process to optimize the use of resources for vector control. Integrated Vector Management (IVM) emphasizes on inter-sectoral collaboration, combination of several vector control methods, and enhancement of capacity building towards sustainability of program. There are increasing research efforts to provide evidence for policy makers on integrated vector management in communities in low-middle income countries. The aim of this study is to review community based intervention studies on vector control with IVM approach in term of effectiveness, time requirements, costs, and sustainability of the intervention program after the research project have stopped.

Methods: Articles were searched on PubMed, ISI Web of Science, and Science Direct with search terms “community”, “environmental management”, “chemical control” or ‘insecticide”, “biology control”, “education campaign”, combined with “dengue” or “Aedes aegypti” or “Aedes albopictus”. Data extracted includes intervention methods, effectiveness outcome, time of outcome assessment, cost of intervention, and sustainability assessment.

Result: We identified 19 articles of 16 studies in 11 countries. 5 studies used environment management, 2 used insecticide treated materials, and 9 combined different methods. Most of the studies reviewed showed that community based intervention programs were more effective than routine vector control program based on chemical control without community participation. Effectiveness was reached after 1 to 2 months. Costs of intervention programs were  lower than routine programs.Only 2 studies evaluated the sustainability of the intervention. However, those indicated that it was feasible to maintain effects of intervention, mobilize the participation of different stakeholder levels. Continuous capacity building enhanced close relationship between community and vector control personnel, contributing to sustaining effects of vector control program.

Conclusion: Integrated vector management appears to be an effective method to control vector populations. There is a need to conduct more studies to evaluate sustainability of these programs, as well as cost-effectiveness analysis to tailor out the optimal intervention strategy.
