Community engagement to control dengue and other vector-borne diseases in Alappuzha municipality, Kerala, India

ABSTRACT

Introduction Vector-borne diseases (VBDs) are a serious threat in many Indian states, including Kerala. Community-based decentralized planning and engagement are effective strategies that can make positive behavioral changes to control VBDs. Methods This community-based implementation research was conducted during November 2016 – October 2018 in Alappuzha municipality in Kerala, India. It was conducted in two phases. In the first phase, formative research was conducted to know the community’s profile and perceptions and thus to plan and develop an appropriate intervention. Baseline data on some entomological indicators were also collected. These data were used to assess the impact of the intervention by comparing with the post-intervention data. In the second phase, an intervention through the community’s engagement was implemented in selected wards. The activities included the formation of community committees and the vector control and source reduction activities with the community engagement and inter-sectoral coordination. Results The intervention resulted in a positive change among the community to engage in vector control activities. These efforts along with inter-sectoral coordination resulted in successfully implementing vector source reduction activities. In both wards, pre- and post-intervention entomological data (house index: 16.7 vs 6.0 and 64.2 vs. 8.6; container index: 24.8 vs. 12.1 and 37.7 vs. 18.1; and Breteau index: 21.3 vs. 7.3 and 47.7 vs. 8.6) revealed a considerable vector source reduction. Conclusion The findings of this study suggest considering and including community engagement in public health policy as the main thrust to control VBDs.
