China’s lessons from Coronavirus to the world

The novel coronavirus widespread from December of 2019 in China has become a global pandemic. As the new cases in China decreased to less than 10 each day and that in other countries increased to more 4000 each day, learn the lessons from China, reflecting what may work and what may don’t can help the world to control the virus and reduce the cost from the virus. The following 11 lessons are not intended to list all the actions taken in China, they may not equally effective, it is only an overview, the reflection is still going on and I hope more people can comment and provide their ideas on this.

(1) Physical distancing, this includes lockdown of the epicenter city, stop of public transportation, the lockdown of communities. Some of these actions has helped other regions to have time to prepare for the arrival of the virus. Two work has examined the effectiveness of these measures: The effect of travel restrictions on the spread of the 2019 novel coronavirus (COVID-19) outbreak, And The impact of transmission control measures during the first 50 days of the COVID-19 epidemic in China,

(2) Social distancing, cancel the mass gathering, close restaurants, cancel meetings, extend the vocation for workers and postpone the school start, encouraging working at home. These actions on the collective actions have reduced the R0 and helped to flatten the curve.

(3) Call for individual behavior change: waring mask, washing hand, stop shaking hand, divide the food on the table or use shared chopsticks or spoons to get the food (分餐制和公筷).

(4) Address the increasing demand for resources, like masks, test kits, protection suits, etc. Collaboration between Red Cross, IoT industries, and volunteers has made this possible and reversed the chaos at the beginning.

(5) create temporal shelter hospitals, two new hospitals were built and 14 temporal shelter hospitals were created from exhibition centre, stadium, etc.

(6) declare a national emergency, and deploy resources all over the country. Especially more than 40,000 doctors and nurses from all over the country were arranged to support Wuhan.

(7) check the temperatures at entering supermarkets, shopping mall and other public spaces.

(8) digital tracing and control, a mobile phone QR code that records everyone’s travel history are widely used on the highway, gate of buildings and markets. The information links to the personal ID and connected to personal records of making phone calls or messages, using Baidu or Gaode maps, using wechat, qq or sino weibo account, linking local wifi and so on. If someone cheats, the local police will find him to know the details. I suppose this virus outbreak will help the population census and know the numbers early.

(9) relief package policies, free test of a suspected case, free canceling flight and train tickets, reduce the rent in shopping malls, eliminate or delay the social security and insurances.

(10) Pay attention to places with concentrated population, like prisons, social welfare homes, churches, etc.

(11) Wildlife protection legislation. China has passed the decision on banning the trading and consumption of wildlife since Feb. 27, 2020, the full document can be found here:
