Technical level may lead to system crash. The population base of China is1400 million people. Unifying all the health codes of all people on one network platform will easily lead to system delay, and the network platform will not be opened during the peak period of health code use. To take a step back, when the epidemic situation is the most serious in some areas, the relevant local departments advocate that people should not open the health code software at will in their spare time, which will cause a great burden to the local health code system. If this measure is extended to national unity, once a large-scale epidemic occurs, it will be a great test of technical level, and if it cannot bear the pressure of population base, it may lead to the collapse of health code system.
Health laws and regulations should be tailored to local conditions, not generalized according to actual conditions. China has a vast land area. The population base of each region is different, the actual environment is different, and the epidemic prevention and control policies are also different. Although the epidemic prevention and control policy of dynamic zero clearance is implemented in most areas of China, the difficulty and division method of high-risk areas and low-risk areas in each area are different. After all the health codes are unified into one platform, it will be more difficult for each region to manage its own epidemic prevention and control. For example, for residents in high-risk areas, there is no way to implement yellow health code epidemic management.
The health coding system is mature, and it will take a long time for the whole country to be unified. In addition to the national unified health code data platform, each province has its own health code software APP, which can handle many other online businesses besides health codes, such as online appointment registration. If the health coding is unified nationwide in the future, it means that the health coding software in all provinces will no longer be used, which will have a heavy economic burden and take a long time to unify, thus delaying the management rules for epidemic prevention and control.
