How often does Shanghai receive SMS big data from the Prevention and Control Office?

Immediately take the initiative to contact the community, unit or hotel where you live, inform you of receiving the short message in time, and implement epidemic prevention and control measures such as nucleic acid detection according to territorial requirements, and at the same time do personal protection. This short message suggests that according to the big data survey, you may have the risk of direct or indirect contact with infected people in COVID-19 in the near future.

Do health monitoring. If you have fever, dry cough, stuffy nose, runny nose, fatigue, sore throat, decreased sense of smell and other symptoms, go to a nearby fever clinic in time, take personal protection on the way and avoid taking public transportation.
