What do community-based dengue control programmes achieve? A systematic review of published evaluations
There is weak evidence that community-based dengue control programmes increase the effectiveness of dengue control programs.
Dengue spread can only be curbed by vector control and body protection. Recent efforts have been focused on community-oriented activities, such as chemical, biological, physical intervention and behavioural change. The aim of this systematic review was to provide an overview of effectiveness of community-based interventions in reducing vector populations for dengue control. All 11 included studies showed a reduction of larval indices or incidence of dengue diseases. Unfortunately, several confounding and bias were identified. The studies were very variable in terms of intervention strategies, main target groups, length and intensity of the intervention and outcome measures.; these factors made it difficult to identify which element was mainly responsible for the effect of the control program.
