1. Lack of trust towards China. By the day China announced the occurence of suspicious pneumonia (Dec 31), they immediately treated this virus as SARS and took preventive actions. This was the press release from the Taiwan CDC and you could note the date posted (Google translate if interested). They were also the first region to close the border against China. https://www.cdc.gov.tw/Bulletin/Detail/zicpvVlBKj-UVeZ5yWBrLQ?typeid=9But I’m guessing it’s citizens are a lot more compliant to Government instructions and perhaps more responsible towards their fellow citizens? What was their secret to success?
2. Banned from the heavily corrupted WHO. The WHO recommendation "not to issue a travelling ban against China" has been proven a joke. In fact, the WHO admitted that they had received an advice from Taiwan warning about this highly infectious virus. What a shame. https://time.com/5826025/taiwan-who-trump-coronavirus-covid19/
3. Self production of rapid detection kits and masks.
4. Adequate policy formulation and compliance.
