Kiến thức, thái độ, thực hành về phòng, chống sốt xuất huyết Dengue của người dân huyện Long Hồ, tỉnh Vĩnh Long năm 2025 và một số yếu tố ảnh hưởng

Dengue hemorrhagic fever (DHF) remains a significant public health threat globally, particularly in Southeast Asia and the Mekong Delta region of Vietnam, where it is endemic and frequently causes large-scale outbreaks. Despite its widespread prevalence and substantial morbidity and mortality, specific treatments are still lacking, making effective prevention crucial. Prevention strategies heavily rely on community engagement, specifically their knowledge, attitudes, and practices (KAP) regarding DHF control. Recognizing this critical need, this study aims to assess the current KAP among residents in Long Ho district, Vinh Long province, in 2025. Furthermore, it seeks to identify key influencing factors that shape these behaviors, providing a foundational understanding for developing targeted and sustainable intervention measures to mitigate DHF transmission at the local level.

Public health practitioners, epidemiologists, policymakers, local healthcare professionals, community leaders, and researchers focused on infectious disease control and health promotion in endemic regions.

This study investigated the knowledge, attitudes, and practices (KAP) concerning Dengue hemorrhagic fever (DHF) control among residents in Long Ho district, Vinh Long province, and identified associated influencing factors. Employing a descriptive cross-sectional design with a mixed-methods approach, data were collected from 420 household representatives and 18 community stakeholders through structured questionnaires, direct observations, and in-depth interviews. The findings revealed that 67.9% of residents demonstrated correct knowledge, 77.9% held correct attitudes, but only 57.9% engaged in appropriate practices for DHF prevention. Statistically significant correlations were observed across knowledge, attitudes, and practices (p < 0.05), indicating that a higher educational level positively influenced knowledge and practical application, while occupation and age group shaped attitudes and practices. Specifically, correct knowledge was strongly linked to appropriate attitudes, and both were crucial for effective practices, consistent with health behavior models. While residents generally exhibited satisfactory knowledge and positive attitudes towards DHF prevention, a noticeable gap existed in the translation of this understanding into consistent practical actions. Key limitations included specific knowledge deficits regarding mosquito behavior and early disease symptoms, and a lower sense of individual responsibility in prevention efforts. The study recommends diversifying health communication strategies, particularly emphasizing regular vector control campaigns and leveraging the influence of community organizations and key individuals to foster sustainable prevention practices. Furthermore, capitalizing on the observed high willingness for DHF vaccination presents a timely opportunity for future immunization programs, thereby strengthening public health responses to DHF in the region.
