A research and development study was conducted from September 2020 to April 2023 involving 9 hospitals, 24 district health centers and 319 commune health stations. The main objective of the study was to establish,
refine, and update a system for controlling directly transmitted diseases in Ho Chi Minh City, as well as assess its practical implementation. Before the system update, the study identified limitations in disease surveillance, particularly in monitoring cases that were not examined or treated at hospitals. The existing reporting
mechanisms also resulted in incomplete disease data, with subpar data quality due to delays and inadequate processing of reported cases. Considering the prevailing circumstances, management requirements and usage needs, the system underwent enhancements and integrated GIS capabilities. This allowed healthcare personnel to swiftly and accurately identify disease cases, determine contacts, establish epidemiological zones, trace
transmission chains, and monitor the implementation of control measures. The improved control system has been successfully implemented, ensuring effective management of community-based hand, foot, and mouth disease. Additionally, the system demonstrates the potential for broader applicability in managing other directly transmitted diseases.
