Abstract

International mass gatherings pose a significant risk for the rapid spread of infectious diseases due to large-scale population movements occurring in a short period and limited access to information on potential outbreaks. The Division of Risk Assessment of the Korea Disease Control and Prevention Agency employs the Epidemic Intelligence from Open Sources (EIOS) system to detect public health threat signals that could impact Koreans in six countries, including Qatar and neighboring countries, during the 2022 International Federation of Association Football World Cup, or enter Republic of Korea (ROK) through visitors. During the surveillance period, the EIOS system collected 18,431 articles related to monitoring the World Cup. Out of the 11 articles classified as public health threats, only one (0.01%) was determined to potentially impact the ROK or Koreans in the countries subjected to surveillance. The EIOS system allows for real-time monitoring of mass gatherings and is particularly useful for international gatherings, especially those hindered by a language barrier. When operating an event-based surveillance system, it is important to consider various factors such as the possibility and impact of a public health threat event, the size of the mass gatherings to be monitored, the level of media attention, available resources, and the sensitivity of the surveillance system. Continuously accumulating experience in operating the EIOS system for international mass gatherings and sharing knowledge with other countries, researchers, and international organizations that use the system are essential steps to enhance its efficiency and effectiveness.
