Why did the green code receive the text message?

The space-time intersection of the received message in green code may be within 14 days, in the same space-time grid as the confirmed patient (usually taking 800 m× 800 m as the detection range), and * * * stays 10 minute.

In layman's terms, for example, if an infected person has been to a place within 14 days, whether you are passing by physically or drifting in the communication signal, it may be considered as time and space. The purpose of screening "time-space companions" is to find the potentially dangerous population to the greatest extent, and to include more people who may be infected with "time-space overlap" in key investigations, so as to truly realize early detection and early prevention and control.

After receiving the news, immediately contact the community, unit or hotel, inform the situation of the news in time, and implement epidemic prevention and control measures such as nucleic acid detection as required, and try not to go out. If you really need to go out, please wear a mask and don't take public transportation. Actively cooperate with the completion of various measures for community epidemic prevention and control, and earnestly fulfill the obligation of epidemic prevention and control.

Healthy green code

The green QR code representing personal health is called health green code. It has three colors, green, yellow and red. Green code: means safer. Yellow code: indicates that you have been to an unsafe area. Red team: People who have had contact with confirmed, suspected and asymptomatic infected people.
