Is the epidemic prevention big data mainly changed?

Epidemic prevention big data is mainly not a change, but also a friend in high-risk areas. When big data tracks that you may have a brief intersection with a confirmed case in time or space, your travel itinerary code will turn yellow. At this time, you need to contact the epidemic prevention department to make a complaint or provide negative proof of nucleic acid test, and the yellow code will change back to the green code. When big data tracks that you have had close contact with confirmed cases, or you are from a middle-high risk area, the travel code will be red and you need to be isolated.
