Public Health Emergency and Crisis Management: Case Study of SARS-CoV-2 Outbreak.

The SARS-CoV-2 pandemic has caused an unparalleled public health crisis, delivering an immense shock to humanity. With the virus's health consequences largely unknown, different health systems around the globe have pursued various avenues of crisis management. South Korea, troubled early by the virus, was once the second most affected nation in the world. Arrays of measures in South Korea, such as large-scale diagnostic testing and technology-based comprehensive contact tracing, have brought about debates among public health experts and medical professionals. This case study describes the major cluster transmissions in SARS-CoV-2 hotspots in South Korea (such as a religious sect, a call center, logistics facilities, and nightclubs) and offers early observations on how South Korean public health authorities acted in response to the initial outbreak of the virus and to the new waves prompted by re-opening economies. We then discuss the way in which South Korea's experience can act as a reference for shaping other countries' public health strategies in pandemic crisis management.
