I have never been to an epidemic area. Why did the health code turn yellow?

We haven't been to the epidemic area, but the health code has turned yellow. This is because we have a "time-space companion" with the patients diagnosed with the epidemic, and we have quietly become a "time-space companion".

"Space-time companion" is a brand-new vocabulary under the prevention and control of epidemic situation. This word sounds beautiful, but in the process of epidemic prevention and control, no one wants to be a "time companion". Because the health code turns yellow, this is not a good phenomenon, which means that we need to isolate and carry out nucleic acid testing.

First, the health code turned yellow when I didn't go to the epidemic area. Just because I became a "time companion", it may sound abstract. If I can give an example, it will be easier to understand. In our work and life, when we go shopping, we will meet many strangers. Although these strangers don't know their names and ages, and they don't know where they come from, they are our "time and space companions" and appear at the same time and place as us.

Among these strangers, once someone is diagnosed as COVID-19, through epidemiological investigation and big data screening, we will become a group that may be infected. In order to attract the attention of epidemic prevention personnel, the health code of all screened people will change from green to yellow.

There are some differences between "time and space companions" and close contacts, but their work and life are still affected by the diagnosed patients. According to relevant statements, there are two criteria to be a "time-space companion".

? 1. Time-space intersection of telephone numbers: If the telephone number of the confirmed patient and the telephone number of our hospital appear in the same time-space grid (the range is 800m*800m) and the intersection time exceeds 10 minute; Plus any party, if the cumulative stay time in the grid exceeds 30 hours, it will be judged as a "time-space companion".

? 2. Intersection within 14 days: In the past14 days, the confirmed patients have intersected with us. Apart from the passing of fate and the drift of communication signals, we will become "time and space companions".

Once recognized as a "space-time companion", the color of the health code will change from green to yellow.

Second, the health code turns yellow. We should do this. The appearance of health code has brought great help to epidemic prevention. Under the epidemic situation, we should always pay attention to the color of our health code. If the green turns yellow or even red, we should pay great attention to it and deal with it according to the following methods.

1, do a good job in personal protection and cancel travel plans: the yellow health code means that we belong to the people who may be infected by the epidemic. Under such circumstances, you can't travel freely like a green code and enter various public places. At this time, personal protection, frequent hand washing and disinfection, and frequent indoor ventilation should be done. At the same time, cancel your various travel plans and isolate yourself at home.

2. Report to the epidemic prevention personnel and obey the work arrangement instructions: after the health code turns yellow, we need to report this situation to the local epidemic prevention department in time and obey their work arrangements and instructions. Do a good job in personal home isolation and cooperate with nucleic acid detection.

After the "time-space companion" is determined, you will generally receive a SMS reminder. At this time, it is necessary to actively cooperate with the epidemic prevention work according to the requirements of SMS and epidemic prevention personnel.

Third, epidemic prevention and control, reduce travel, and do a good job of protection. It's autumn and winter. As the temperature drops, epidemics and influenza are also at the peak of transmission and infection. In view of this season, we should go out less and cancel our plans to travel abroad. Try not to go to the gathering place if it is not necessary. When traveling, do a good job of personal protection. In addition to wearing a mask, you need to wash your hands and disinfect frequently.

If you have symptoms such as fever, cough and fatigue, you need to go to the designated fever clinic in time. On the way to see a doctor, try to avoid taking public transport, driving or riding a bike.
