How often does the second secretary receive short messages from the Shanghai Prevention and Control Office?

Under normal circumstances, you will receive SMS notification immediately.

If you are found to be a secret recipient during the screening, I will send you a text message or call you as soon as possible, let you report the travel trajectory during this time, let you isolate it, and then make reasonable arrangements.

Don't panic at this time. The second close contact doesn't mean it is COVID-19. You will judge by nucleic acid examination and separation. Only when you find any discomfort, you must report it as soon as possible.
