South Korea's Test and Trace system

South Korea’s Test and Trace system is a comprehensive public health strategy designed to detect, track, and contain COVID-19. It rapidly tests individuals with symptoms or exposure, then uses digital tools like QR codes and mobile apps to identify and notify close contacts. This allows authorities to isolate confirmed cases quickly and quarantine those at risk, minimizing the spread. The system relies on data sharing between health agencies and businesses, ensuring timely updates and effective containment. Overall, it integrates testing, technology, and contact tracing to control outbreaks efficiently while maintaining privacy safeguards.
