I stayed at home for a month. Why is the health code red?

If an individual thinks that it is inconsistent with the actual situation, he can apply through the hotline 12345 or the error correction function, and the county-level prevention and control headquarters will verify that it is necessary to modify it, and the modification will be completed in the background.

There are many reasons why health codes turn red. May be with a mobile phone, across provinces and cities, to some places with serious epidemic. Maybe my mobile phone was mailed to different provinces and cities when it was turned on. Maybe it's the GPD positioning error of my mobile phone. Besides, maybe my temperature is too high and I have a fever.

Health code function:

There are three kinds of "health codes": the green code can directly enter Hangzhou, the red code is isolated for 14 days, and the yellow code is isolated for less than 7 days. The management information system of "health code" in Zhejiang Province is based on real data, connected with relevant databases such as the dynamic control list of key personnel, and distributed "health code" according to the results of checking and comparing the information declared by the masses with the background data. The health coding system has formed a set of standards, which can be quickly introduced according to the needs of different regions and the needs of epidemic prevention and control in various places.
