Two important things:
1. Taiwan knew in DecemberIt was human-to human transmissible, sent notification to WHO. The WHO threw it in the waste basket. But Taiwan prepared,
2. Taiwan president Tsai Ing-Wen spoke in favor of the Hong Kong protesters last Fall angering the CCP, who then tried to punish her and Taiwan by clamping down on travel between China and Taiwan, which, as it turns out, limited contact between infected people of Wuhan and the Taiwanese. Backfire!
“Limited” contact is still 4-6 flights a day operating directly between Wuhan and Taipei through December and January.
