How does Gansu health code become "green code" after it becomes "yellow code"? How is the risk area delineated?

Gansu health code becomes? Yellow code? How to convert it into? Green code, the definition of risk area: first, there are no confirmed cases in low-risk areas or no newly confirmed cases in recent 14 days; Secondly, the medium-risk area is a city where positive patients or asymptomatic infected people stay for a period of time; Third, there have been corresponding newly confirmed cases in high-risk areas in the last three days. It is necessary to elaborate and analyze the changes of Gansu health code from the following three aspects. Yellow code? How to convert it into? Green code? , how the risk area is specifically delineated.

1. No confirmed cases in low-risk areas or no newly confirmed cases in the past 14 days?

First of all, there are no confirmed cases in low-risk areas or no newly confirmed cases in the past 14 days. It is very safe for people to travel in low-risk areas, mainly because some corresponding security risks are controllable, and there are basically no hidden viruses in the city, which is very friendly to people who want to travel.

Second, the middle-risk area is a city where positive patients or asymptomatic infected people stay for a period of time?

Secondly, the middle-risk area is a city with positive patients or asymptomatic infected people staying for a period of time, and its own level is still relatively high for the middle-risk area, so people who want to go to the corresponding middle-risk area still need to provide the corresponding negative proof of nucleic acid testing, and at the same time need to provide their own travel code proof, and they still need to be isolated and observed when they arrive at the corresponding place.

3. Have there been corresponding newly confirmed cases in high-risk areas in the past 3 days?

Moreover, there are corresponding new confirmed cases in high-risk areas in the past three days, which is very dangerous for anyone. Therefore, for high-risk areas, local closure or comprehensive risk control is generally adopted to solve the corresponding problems. After all, for high-risk areas, there are many confirmed cases and it is easy to cause the epidemic to flow out.

What should people pay attention to:

When choosing some cities, we should pay attention to verifying the epidemic prevention level.
