Before revision: The simulations show that the model captures  the pandemic dynamics in South Korea accurately , which provides confidence in the model predictions and its future use  .
After revision: The simulations show that the model captures the pandemic dynamics in South Korea accurately , which provides confidence in the model predictions and its future use . In particular, the model predicts that about 40\% of the infections were not documented, which implies that asymptomatic infections contribute silently but substantially to the spread of the disease indicating that more widespread asymptomatic testing is necessary .
