The causes of discoloration of health regulations can be roughly divided into four categories.
The first category is people who have had contact history with confirmed cases or asymptomatic infected people in COVID-19, including close contacts, sub-close contacts and close contacts in time and space. The so-called close contact in time and space refers to the key population who may be exposed to more than 1 hour at the same time, in the same place and within 250 meters around from 4 days before the onset of a confirmed case or asymptomatic infected person to the time of isolation control.
The second reason for the discoloration is that I have been to the high-risk areas of COVID-19 epidemic.
The third category is that the information reported when reporting the health code is inaccurate.
The fourth category is other people who have been included in the COVID-19 epidemic prevention and control platform for investigation and verification.
What if the hygiene code turns yellow and red?
Once you find that the health code changes color, you should first report it to your community at the first time, and provide your recent living history, contact history and personal health status truthfully and accurately. While reporting, take precautions and don't be alone. Wear a mask correctly, maintain personal hygiene, don't go out and walk around at will, and don't throw away personal garbage at will. Avoid contact with family members; Do not enter public places, including hotels, shopping malls, supermarkets, cinemas, KTV, bars and other crowded places; Don't take public transportation, including taxis, buses, planes, trains and buses. We should actively cooperate with the investigation, wait patiently for the door-to-door visits of local community workers such as epidemic prevention in the original station, and actively cooperate with epidemiological investigation, medical investigation, health monitoring, isolation control and other work.
How to switch back to "green code" after health code changes color?
Personal information has been reported. After verification of personal recent residence history, contact history and personal health status, the situation that may cause red and yellow codes is excluded. After being returned by local community workers such as epidemic prevention, the health code will become a green code. For those who have contact history with confirmed cases or asymptomatic infected persons in COVID-19 and have been to high-risk areas of COVID-19, health management and control should be completed according to local epidemic control regulations. After control, the health code will turn into a green code. If the information is inaccurate, please "re-fill in" on the health code page of "Zhejiang APP". After filling in the relevant information truthfully and accurately, the health code will become a green code.
