Dissemination of misinformation during the dengue outbreak in Bangladesh

Purpose This study aims to investigate the role and perceptions of misinformation on dengue among Bangladeshi citizens during dengue outbreaks. It examines the prevalence, sources and factors contributing to the spread and acceptance of dengue-related misinformation, as well as strategies to counter misinformation. Design/methodology/approach An online survey was conducted in Bangladesh from October 2023 to February 2024 using a convenience sampling method. The questionnaire gathered demographic information, ratings of agreement with statements related to dengue misinformation and opinions on strategies to combat misinformation.

Findings The findings reveal a lower prevalence of misinformation beliefs about dengue, although belief levels vary based on demographic factors, such as gender, education level, sources of information and information literacy. Social media emerged as the primary source for obtaining dengue-related information. Respondents strongly supported strategies like eradicating false social media content, providing straightforward and easy-to-understand information and promoting information, media and health literacy. Research limitations/implications The study highlights the role of demographic characteristics and information sources in shaping misinformation beliefs and offers evidence-based recommendations to counter misinformation, thereby improving dengue control efforts in Bangladesh. Originality/value This research provides critical insights into the challenges posed by misinformation during disease outbreaks and proposes actionable strategies to combat its dissemination.
