Why did the health code suddenly disappear?

Wechat health code cannot be used, which may be caused by mobile phone network. This may happen if the mobile phone has a poor network speed or no network connection. Users are advised to check the mobile phone network status or disconnect the mobile phone network connection.

Different provinces have different risk levels, response levels and prevention and control requirements. Secondly, the standards for generating health codes vary from place to place. The health code can only prove the patient's condition at that time, and the subsequent health status cannot be simply judged accordingly.

At the national level, the risk data service of epidemic prevention and control in COVID-19 is carried out nationwide, and all provinces and departments can call and query the unified database of confirmed and suspected cases, close contacts database and county-level risk grade database, basically realizing mutual recognition of basic data.

The positive role of health regulations in the process of efficient and accurate epidemic prevention has been officially recognized. The Ministry of Industry and Information Technology encourages all provinces to strengthen their own prevention and control, trust and benefit each other, and provide convenience for people who resume their work and production. Triple value of health code:

1, reducing the "table epidemic prevention" and facilitating personal travel. Complete the online newspaper once and use it many times, which greatly reduces the trouble brought to individuals. It not only saves time, reduces the infection risk of crowd gathering, but also effectively solves the "difficulty in getting in and out" when returning to work.

2. Improve the efficiency of joint defense and joint control in COVID-19. Scanning codes to report health information is conducive to real-time monitoring and management by relevant government functional departments and improves statistical efficiency.

3, easy to return to work, resume production, and restore school management. Through the health code, enterprises, universities, primary and secondary schools and other units can timely and effectively grasp the health information of their employees, teachers and students, and can take targeted and accurate joint prevention and control measures to avoid the outbreak of COVID-19 epidemic after the resumption of work.
