Prevention and control of dengue and Aedes mosquitoes in South and Southeast Asia: Interventions, challenges, and future recommendations.

Dengue fever, caused by a virus transmitted through Aedes mosquitoes, has become a major health issue in South and Southeast Asia. This review explores various preventive and control interventions for dengue implemented in South and Southeast Asia, the challenges faced, and recommendations to enhance the sustainability and effectiveness of these control efforts. The scoping review was conducted by searching articles published between 2014 and 2024 through databases such as PubMed, Scopus, ScienceDirect, Web of Science, and ProQuest. A total of 1599 studies were identified, and 25 articles were eventually analyzed. The findings indicate various intervention approaches in both regions. Key challenges identified in this review include community engagement and participation, resource, logistics, and data management issues, public perceptions and knowledge, control methods and evaluation of effectiveness, and social and economic issues. These challenges hinder the effectiveness of interventions. Recommendations to strengthen future interventions include: enhancing community involvement through continuous training, improving monitoring and evaluation with technology-based solutions, and expanding the use of technologies like Wolbachia-infected mosquitoes and spatial repellents. Expanding public awareness campaigns, strengthening school and community-based education, and improving training for health workers are also essential. Lastly, adopting a combined approach is crucial for achieving more effective and sustainable results in dengue prevention.
