Recently, 31 provinces (autonomous regions and municipalities directly under the Central Government) and the Xinjiang Production and Construction Corps reported a rapid increase in the number of new local infections, and the proportion of asymptomatic infections has increased nationwide. The situation of epidemic prevention and control is grim.

In order to detect infected persons as early as possible in a shorter period of time and control the source of infection, the government has also released a new version of the nucleic acid testing guidelines - "Regional Novel Coronavirus Nucleic Acid Testing Organization Implementation Guidelines (Third Edition)". Nucleic acid detection protocol.

What important changes will there be in nucleic acid testing in the future?

Will it be more accurate to change "all staff" to "area"?

How is the "region" defined?

Is there a time requirement for nucleic acid testing of the "area"?

How are the sampling points arranged?

Take you to understand.
