Knowledge, Attitudes and Practices Towards Dengue Fever, Vector Control, and Vaccine Acceptance Among the General Population in Countries from Latin America and Asia Pacific: A Cross Sectional Study (GEMKAP)

his study, published in Vaccines, explored knowledge, attitudes, and practices towards dengue, vector control, prevention, and vaccination in Argentina, Brazil, Colombia, Mexico, Indonesia, Malaysia, and Singapore.

A cross-sectional, quantitative, electronic survey was administered to a nationally representative adult population (n=3800) in Argentina, Brazil, Colombia, Mexico, Indonesia, Malaysia, and Singapore. The Capability, Opportunity, Motivation for Behaviour Change (COM-B) framework was used to identify factors correlated with dengue vaccine(s) uptake.

 

Findings show that there was a low global score for Knowledge (48%) and Practice (44%), and a moderate score for Attitude (66%); scores were comparable across countries. Of all respondents, 53% had a high willingness (scoring 8-10/10) to vaccinate against dengue, which was higher at 59% in Latin America countries (Argentina, Brazil, Colombia, Mexico) than in Asia Pacific countries at 40% (Indonesia, Malaysia, Singapore). Key factors significantly (p<0.05) associated with increased willingness to vaccinate included accessibility to the public (subsidies and incentives) and trust in the healthcare system and government.

 

A common approach to dengue prevention across endemic countries – with some country-specific customisation such as education, vaccination, and vector control (multi-pronged) – may reduce dengue burden and improve outcomes.
