[Event-Based Surveillance of Foreign Infectious Disease Outbreak: from November, 2021 to October, 2022]

The Division of Risk Assessment in Korea Disease Control and Prevention Agency has operated event-based surveillance (EBS) for early detection of foreign infectious disease outbreak and risk communication. In this report, we analyzed descriptive statistics of events which is registered on EBS database from November 2021 to October 2022 and present the descriptive statistics of the collected events using several criteria, including collection time, data sources, disease type, continents affected by outbreaks, and communication. In discussion, we address the need to enhance speed, accuracy and precision in detecting infectious disease outbreak events. Additionally, we propose expanding local public health network, active information sharing between open-source epidemic intelligence system users and training experts on EBS as solutions to improve current EBS.
