Objective: To assess the current status of the infectious disease surveillance system in Da Nang city and identify factors associated with the effectiveness of surveillance activities.
Methods: A cross-sectional study employing a mixed-methods design (quantitative and qualitative) was carried out from February to June 2025. The data collection sites included the City Center for Disease Control, 7 district/county health centers, 3 hospitals, and 47 commune/ward health stations. The study involved a quantitative survey of 200 healthcare workers, complemented by in-depth interviews with 20 unit leaders.
Results: The infectious disease surveillance system in Da Nang is organized across 3 administrative levels and generally meets local surveillance requirements. Approximately 98% of health workers perceived the system to be effective, and reporting compliance ranged from 97.9-100% across all levels. However, data analysis capacity at the primary health care level remains limited, with only 43.5% of staff performing routine data analysis. The use of epidemic alert thresholds is not widely implemented, and coordination with the private health sector remains inadequate. Key barriers include shortages of trained epidemiological staff, multiple responsibilities among health workers, and unstable reporting software.
Conclusions: Although the infectious disease surveillance system in Da Nang has a relatively strong organizational foundation, strengthening proactive surveillance capacity at the primary health care level is necessary through workforce training, upgrading surveillance software, and improving coordination with the private health sector.
