Generally speaking, only people who come from or pass through high-risk areas within 14 days need to be quarantined after arriving at their destination.
However, if you only pass through the middle and high-risk area, but you don't stop or get on or off, then the background communication big data will generally not record it as a road or a visit. At this time, there is generally no great risk and there is no need for isolation. The specific needs are determined according to the local epidemic prevention policy.
Whether the transfer health code in high-risk areas will change depends on the situation.
At present, many stations have in-station transfer channels, so if you transfer in the station through a dedicated channel and don't leave the station, and the stay time is not long, then you generally don't need to scan the code to enter the station. At this time, the health code generally does not change color.
However, if you stay too long or accidentally leave the station, you need to scan the health code again with your mobile phone when you enter the station again. Personal information will be left at this time, and the health code may change color.
Similarly, which is more susceptible to infection, airplanes or high-speed trains.
Aircraft and high-speed rail are public transport, and the internal environment is relatively closed. Therefore, in front of infected people in COVID-19, if you don't pay attention to wearing masks and taking personal protective measures, you will be easily infected.
However, generally speaking, the number of passengers on the plane is relatively small, and point-to-point transportation is implemented, and there will be no shifts in the middle. There are many stops on the high-speed rail and the traffic is relatively large, so the situation on the high-speed rail will be more complicated.
Do I need to bring a paper nucleic acid test report when flying? Generally speaking, it is not necessary.
At present, nucleic acid detection reports can be mainly divided into electronic version and paper version. As long as they are valid, both of them have the same legal effect, so they can be used.
Because the paper version of the nucleic acid detection report usually needs to be printed at the detection point, which is more troublesome, it is more convenient to open the electronic version of the nucleic acid detection report to the staff when flying.
