Passing through the epidemic area: Many times we don't really reach the epidemic area, but as long as we pass through these areas and stay here for a short time, our health code may change color because of short contact. The green health code is unimpeded, and the yellow health code is difficult to move. In life, we should always pay attention to the color of our health code. If it is yellow, we must be vigilant. Actively report this situation to the local area and obey the arrangement of epidemic prevention personnel. There is a situation of "time and space accompanying": if you don't go to the epidemic area, the health code will still change color. The most likely scenario is to have a "time companion". People who appear in the same space within a certain period of time are diagnosed as patients with COVID-19's disease. In this case, we will also be regarded as cryptographers or sub-cryptographers. In order to cut off the chain of epidemic spread and put an end to all possible ways of transmission. As a person who may be infected, he will mark the epidemic situation and do a good job in isolation and nucleic acid detection. Under the epidemic situation, you should stay in the city where you work and live honestly, and don't go out of the city unless necessary, let alone travel easily across provinces.
There are five kinds of electronic card code colors: green indicates the current Su Kang code green code, has never been to the city where the high-risk area is located, and has a negative nucleic acid certificate within 48 hours. Yellow stands for Su Kang code. Code yellow. Orange indicates that the Su Kang code has expired, or the negative nucleic acid certificate has exceeded 48 hours, or there is a trip to the city where the high-risk area is located, or the trip card has not been verified that day. Red indicates abnormal nucleic acid or Su Kang code red. Gray indicates that the card has not been activated and is in the state of approval or deactivation.
