Generally, the health code does not judge the color of the health code by grabbing the location information, so the health code will not change color if it only passes through the middle and high risk area.
However, if you ride in the same vehicle as a confirmed case, a suspected case or an asymptomatic infected person, or stay in a medium-high risk area for more than 4 hours, then the personal health code may change color at this time.
Is it necessary to isolate when passing through medium and high risk areas? It depends.
If you pass through a high-risk area, generally speaking, the personal health code and travel code will also change to some extent. Whether it is necessary to isolate at this time needs to be decided according to the individual's specific situation.
It is suggested that it is best to report to the local (village, town, unit) epidemic prevention personnel in advance to cooperate with the work and complete the epidemiological investigation. If you have really been to high-risk areas, you need to observe them in isolation. If you haven't been there, there is generally no need for isolation.
3 How long do you need to stay? Generally speaking, the medium-risk area refers to more than 4 hours.
"Path" refers to turning on the mobile phone and staying in the middle and high risk area for more than 4 hours or more. At this time, communication big data will be automatically recorded as path or access, so personal health code and travel code will also change.
However, if you just drive, pass by by car or stay for less than 4 hours, it will not be recorded as an on-the-way or visit, and your health code and itinerary code will not be affected at this time.
How to apply for the health code to turn yellow depends on the situation.
There are many reasons why the health code turns yellow. For the yellow code caused by different reasons, different methods are needed to apply for turning green.
If the yellow code is a confirmed case or an asymptomatic infected person who has been cured, it needs to complete the health management service for 14 days, and then complete the health monitoring for 14 days and the nucleic acid test is negative before it can be turned into a green code.
If it is the yellow code of the confirmed cases, close contacts and sub-close contacts of asymptomatic infected persons, then it usually takes 7 days of health monitoring, and the nucleic acid test is negative, then it can be turned into a green code.
