What is the stalk of green code into yellow code?

The conversion from green code to yellow code should not be underestimated, and it is most important to find out the reason.

We know that the green code is a green QR code representing our personal health; The yellow code indicates that the resident has been to the risk area or had close contact with the confirmed case, and the yellow code is sent to him; Red team said that the current personnel are suspected cases, fever cases or even confirmed cases or asymptomatic infected persons.

If the health code of residents changes from green to yellow, it may be inferred that the following conditions exist: 1, and the health status is abnormal and the symptoms are similar, such as fever and respiratory symptoms. 2. Returnees from other places need to be isolated at home 14 days. 3. Have had time and space with the confirmed patients within 14 days. Spatio-temporal accompaniment is a new epidemic term here, which means staying in the same spatio-temporal grid with the confirmed patient within 14 days (usually taking 800 m *800 m as the detection range) and * * * staying 10 minute.

After the system is tested, the health code will turn yellow. At the same time, if it is considered inconsistent with the actual situation, an application can also be initiated through the hotline 12345, and the revision can be completed after verification and confirmation by the county-level epidemic prevention and control headquarters. I hope this experience will be helpful to everyone, and at the same time, I urge everyone to wear masks when going out, gather less, wash their hands frequently and disinfect frequently.
