Dengue Vector Control through Community Empowerment: Lessons Learned from a Community-Based Study in Yogyakarta, Indonesia

Abstract

Effort to control dengue transmission requires community participation to ensure its sustainability. We carried out a knowledge attitude and practice (KAP) survey of dengue prevention to inform the design of a vector control intervention. A cross-sectional survey was conducted in June–August 2014 among 521 households in two villages of Yogyakarta, Indonesia. Demographic characteristics and KAP questions were asked using a self-managed questionnaire. Knowledge, attitudes and practice scores were summarized for the population according to sex, age, occupation and education. The average knowledge score was rather poor—3.7 out of 8—although both attitude and practice scores were good: 25.5 out of 32 and 9.2 out of 11 respectively. The best knowledge within the different groups were found among women, the age group 30–44 years, people with a university degree and government employees. Best practice scores were found among retired people and housewives. There were several significant gaps in knowledge with respect to basic dengue symptoms, preventive practices and biting and breeding habits of the Aedes mosquito. In contrast, people’s practices were considered good, although many respondents failed to recognize outdoor containers as mosquito breeding sites. Accordingly, we developed a vector control card to support people’s container cleaning practices. The card was assessed for eight consecutive weeks in 2015, with pre-post larvae positive houses and containers as primary outcome measures. The use of control cards reached a low engagement of the community. Despite ongoing campaigns aiming to engage the community in dengue prevention, knowledge levels were meagre and adherence to taught routines poor in many societal groups. To increase motivation levels, bottom-up strategies are needed to involve all community members in dengue control, not only those that already comply with best practices.

Knowledge, attitude and practice on dengue prevention and dengue seroprevalence in a dengue hotspot in Malaysia: A cross-sectional study

“…Therefore, heightening awareness and good attitude and positive encouragement of subsequent good practices are important. Seeing results (eg reduction in Aedes population or dengue cases) of their preventive behaviours may fuel continuous motivation to perform these activities 69 . Besides, it is envisaged that with the new proactive paradigms like informing residents when dengue positive mosquitoes are obtained may improve their attitude and practice and to carry out source reduction 70 .…”

Community-Based Healthcare Programs Sustainability Impact on the Sustainability of Host Organizations: A Structural Equation Modeling Analysis

“…The literature on healthcare community-based programs or initiatives is very diverse [103]. Most of the papers have described and analyzed specific factors for the success or continuity of CbPs [103,104,105].…”

Fostering social innovation and building adaptive capacity for dengue control in Cambodia: a case study

“…As the proposed project planned to scale up existing community-based dengue vector control approaches, for which there is already extensive and contextualized experience, the project team has looked into the needs, expectations, concerns, desires and knowledge in relation to health of the Cambodian communities and stakeholders from various sectors. Motivated, empowered and well-informed multi-stakeholder and gender-diverse groups, whose area of influence span multiple administrative and institutional scales, should be better able to identify and sustainably implement adaptive dengue control strategies, as they are better equipped to understand the tools available to them and mitigate cross-scale social and ecological drivers of disease emergence [ 31 , 32 ]. Through its participatory activities and empowering interventions, the project deliberately focused on building adaptive capacity through key community and school driven social innovations.…”
