Hangzhou, the capital of Zhejiang Province, reacted quickly to COVID-19 before the city had any confirmed cases. Hangzhou, where Alibaba is headquartered, was one of the first cities to use big data and QR code system in the prevention and control of COVID-19. They named the approach “one map, one QR code, and one index.”
It’s been two weeks since select businesses and organizations have been allowed to reopen to workers. Here are policies they implemented:
Step 1: Businesses reopened in several phases based on priorities. For example, healthcare-related facilities were allowed to open first.
Step 2: Restrictions were eased based on track records.
Implementation
Health QR codes were established for everyone in the city and everyone who entered the city as shown in Figure 1.
The yellow and red codes can be turned green after the quarantine time. This health surveillance system has been applied in most cities in Zhejiang Province, and will be implemented in other provinces.
Each individual must monitor and record their temperature and update their profile daily in order to maintain their health status level. The health database is closely monitored by Hangzhou’s Center for Disease Control and Prevention. These new technologies have so far proven to be very effective, at least in Hangzhou. While it’s challenging to effectively detect travelers who might bring COVID-19 back to the city.

Implementation

- The green code allows you to move freely.
- The yellow code requires a seven-day self-quarantine.
- The red code requires a 14-day self-quarantine.

The utilization of technologies are lesson for the other countries. It could also help us think about how to modernize disease control and prevention...
