Systematic Review of Impacts of Educational Interventions to Control Breeding Sites of Aedes aegypti and Aedes albopictus Mosquitoes.

Abstract

Community participation is a critical element in the management of Aedes aegypti and Aedes albopictus breeding sites. Many educational interventions have been conducted to encourage prevention and elimination of breeding sites among different community actors, such as government-run programs for vector surveillance aimed at preventing and eliminating breeding sites at the household level within a community. Getting people involved in prevention and elimination of vector breeding sites in their communities requires communication and social mobilization strategies to promote and reinforce those prevention actions that, in turn, should be effective from the entomological standpoint. Articles published in English, Spanish, and Portuguese, were reviewed to assess whether educational interventions targeting Ae. aegypti and Ae. albopictus were effective in reducing entomological indicators or in improving practices to prevent the presence of or eliminate breeding sites. The most widely used indicators were larval indices and the practices associated with reducing/eliminating breeding sites. We found that using a community-based approach adapted to eco-epidemiological and sociocultural scenarios explains the reduction of entomological indicators by educational interventions. Those who design or implement educational interventions should strengthen the evaluation of those interventions using qualitative approaches that provide a more complete picture of the social context and the barriers and facilitators to implementing vector control. Engaging school children in cross-sectorial collaboration involving the health and education spheres promotes the participation of the community in vector surveillance and reduces the risk of arboviral disease transmission.
