Why did you suddenly receive a short message from Shenzhen CDC for three days and three inspections?

In Shenzhen, three times a day means doing nucleic acid tests three or two times a day. This nucleic acid needs to be converted into hours to calculate, that is, it takes 24 hours for the nucleic acid to be negative for three days. At present, many communities and offices need 24-hour negative nucleic acid test results, and they need three tests every three days. Since the outbreak of COVID-19 in 2020, large-scale detection of nucleic acid has become the best way to deal with the COVID-19 epidemic.

Epidemic prevention is everyone's responsibility.
