I stayed at home for five days and made nucleic acids three times. My health is green, and I was suddenly told to take it to the hotel for isolation. What is the reason?

This is because big data found out whether you are a secret or a sub-secret.

Recently, your activity trajectory may pass through the middle-high risk area, or you haven't brought your mobile phone to the middle-high risk area.

In order to prevent the epidemic from escalating, the big data survey asked you to go to the hotel for isolation. We still have to cooperate with the requirements of relevant departments, and we will be more at ease after centralized isolation. Moreover, isolation in many places is free now, which can also reduce the burden of isolation personnel.
