The mobile phone did not inform all the nucleic acid staff, but began to inform all the nucleic acid staff.

The mobile phone didn't inform you. It may have been notified by other means or channels. If you know, you have to do a nucleic acid test. If you don't know, it's because you haven't been informed, and you don't bear the bad consequences. In order to prevent the spread of the epidemic, some areas will carry out the whole process of nucleic acid testing, which can identify risk personnel in a short time and further reduce the risk of epidemic spread. It is everyone's obligation to do full-time nucleic acid testing, and everyone needs to do it, especially adults. If you don't do nucleic acid testing, it will cause adverse effects and you need to bear certain legal responsibilities. Due to the rebound of epidemic situation in some areas, in order to prevent the spread of epidemic situation, all people in some areas were tested for nucleic acid. Everyone needs to have a nucleic acid test, including the elderly and children. Without nucleic acid testing, no one will find it in a short time, but once there is an epidemic loophole, it will bear the corresponding punishment and legal investigation.
