Why not send text messages to do nucleic acid?

I don't send text messages to do nucleic acid because I haven't been to high-risk areas. I received the SMS notification because I have been to a place where the epidemic is serious, or because I have time and space overlap with patients. In order to prevent and control the epidemic situation, after analyzing big data, the mobile network and the National Center for Epidemic Prevention will send text messages to remind people who have crossed to do a good job in nucleic acid inspection, just in case. Those who haven't been there won't receive text messages.
