On January 4, the Central Epidemic Command Center (CECC) pointed out that the following epidemic prevention and control measures have been implemented in response to cluster infections at Taiwan Taoyuan International Airport:

A. Setting up an incident command post.

B. Re-evaluating the risks involved in the route arrangement for high-risk arrivals (experiencing symptoms in the last 14 days).

C. Expanding tracing to include other personnel who might have been in the areas visited by the confirmed case (e.g. the restrooms the case cleaned) and rapidly conducting related screening.
