Background: Dengue fever is an acute infectious disease caused by the Dengue virus, transmitted via *Aedes* mosquito vectors (WHO, 2024). In Binh Duong province, 1,286 Dengue fever cases and one death were recorded by the 31st week of 2024-ranking fourth highest among the 20 southern provinces (Pasteur Institute Ho Chi Minh City, 2024). Despite the comprehensive implementation of surveillance and prevention activities, their effectiveness remains limited. Objective: To describe the current status of dengue fever surveillance in Thuan An City, Binh Duong Province, 2024. Materials and methods: A quantitative cross-sectional study analyzing 512 cases recorded in the reporting software (in accordance with Ministry of Health Circular 54) with treatment dates ranging from January 2024 to June 2024. Results: Among the 512 reported cases, there were 84 duplicate reports and 79 reports submitted behind schedule. Factors affecting surveillance data quality included: the long interval since training on the infectious disease surveillance management software was conducted at hospitals (2017 and 2018), a lack of internal quality control in surveillance activities, and issues related to the personnel responsible for reporting. Conclusions: The rates of duplicate and delayed reports remained high, at 16.4% and 18.5%, respectively. Factors affecting surveillance data quality included: the long interval since training on the infectious disease surveillance management software was conducted at hospitals (2017 and 2018), a lack of internal quality control in surveillance activities, and issues related to the personnel responsible for reporting.
