Health codes are based on real data and can be generated by citizens or people who have returned to work through online declaration and background audit. As an individual entering and leaving electronic certificate locally, the QR code can be declared once, which is universal in the whole city. The introduction of the health code aims to make the work of returning to work more accurate, scientific and orderly.
The promulgation of various health codes highlights the innovative thinking of local governments in the management of major public emergencies. However, in order to further open up the blocking points of people flow and logistics in epidemic prevention and control and resumption of production and work, it is necessary to rely on a more precise and flexible governance model, so that the application of technology can better escort the epidemic prevention and control.
On May 24, 2020, Hangzhou Health and Wellness Committee put forward the design idea of "knowing health by one code": by integrating the relevant data of electronic medical records, physical examination and lifestyle management, and on the basis of associating health indicators with the color of health codes, explore the establishment of personal health index rankings. At the same time, health groups such as corridors, communities and enterprises can also be evaluated through big data.
