COVID-19 remains one of the most significant public health challenges of the 21st century, causing widespread illness, economic disruption, and social impact across the globe. Effective surveillance is critical for detecting new cases, monitoring trends, and guiding timely interventions to prevent outbreaks.
This presentation outlines the design of a comprehensive COVID-19 surveillance system (C19) that integrates multiple surveillance approaches—passive, active, sentinel, syndromic, and event-based—to ensure early detection and rapid response. It also highlights the legal and ethical considerations, clear case definitions, and collaboration among key stakeholders including the Ministry of Health, laboratories, and community health workers.
Furthermore, the presentation illustrates the data flow, collection, and transfer methods using digital tools such as electronic reporting systems, mobile applications, and cloud databases. It emphasizes the importance of data utilization and dissemination for decision-making, as well as the evaluation indicators that measure information quality, system performance, and user satisfaction.
Through this integrated approach, the COVID-19 surveillance system aims to enhance national preparedness, support evidence-based public health action, and protect communities from ongoing and future outbreaks.
