What if there is no mobile phone?

If the child is told by SMS that he doesn't have a mobile phone, use the parent's mobile phone number. After receiving the message, take the message to the nucleic acid point and ask him to do a single tube for you. There are no other requirements. If (single tube) is positive, the general health treasure will not show it, and there will be special disease control and public security to inform you. At present, the requirement for positivity, if mild or asymptomatic, is generally isolated at home. If you feel worse, you should go to a designated hospital for treatment.
