The traditional model for dengue control in Brazil has established that community participation is one of its main strategic pillars. In practice, this strategy has been unable to promote the involvement and behaviour change of the population, which are considered essential to control this endemic disease. In the present study, we carried out an integrative review of articles published in the scientific literature on knowledge, attitudes and practices of the population about the disease. This method was chosen because it allows gathering and synthesizing research findings on the selected theme, thus contributing to enhance knowledge on the investigated subject. We conclude that there is a gap between the government's actions and the population's reality, which suggests the need to implement a less vertical prevention and control policy, in which social knowledge can guide strategies for disease control in accordance with the community's interests, needs, desires and worldviews. In this perspective, the population ceases to be a mere spectator, dependent on previously defined actions, and occupies a prominent position in the process, ensuring the effectiveness and sustainability of the program's activities.

Background: Five studies were conducted in Fortaleza (Brazil), Girardot (Colombia), Machala (Ecuador), Acapulco (Mexico), and Salto (Uruguay) to assess dengue vector control interventions tailored to the context. The studies involved the community explicitly in the implementation, and focused on the most productive breeding places for Aedes aegypti. This article reports the cost analysis of these interventions. Methods: We conducted the costing from the perspective of the vector control program. We collected data on quantities and unit costs of the resources used to deliver the interventions. Comparable information was requested for the routine activities. Cost items were classified, analyzed descriptively, and aggregated to calculate total costs, costs per house reached, and incremental costs. Results: Cost per house of the interventions were $18.89 (Fortaleza), $21.86 (Girardot), $30.61 (Machala), $39.47 (Acapulco), and $6.98 (Salto). Intervention components that focused mainly on changes to the established vector control programs seem affordable; cost savings were identified in Salto (−21%) and the clean patio component in Machala (−12%). An incremental cost of 10% was estimated in Fortaleza. On the other hand, there were also completely new components that would require sizeable financial efforts (installing insecticide-treated nets in Girardot and Acapulco costs $16.97 and $24.96 per house, respectively). Conclusions: The interventions are promising, seem affordable and may improve the cost profile of the established vector control programs. The costs of the new components could be considerable, and should be assessed in relation to the benefits in reduced dengue burden.
