A South Korean tabletop exercise on emergency responses to a fictional mysterious outbreak led directly to tools the country deployed less than a month later to manage the arrival and spread of the coronavirus, one of the experts involved said

According to an undisclosed government document, on Dec. 17 two dozen leading South Korean infectious diseases specialists tackled a worrying scenario: a South Korean family contracts pneumonia after a trip to China, where cases of an unidentified disease had arisen.

The hypothetical disease quickly spreads among the colleagues of the family members and medical workers who treated them. In response, the team of experts at the Korea Centers for Disease Control and Prevention (KCDC) developed an algorithm to find the pathogen and its origin, as well as testing techniques.
