In order to effectively respond to the possible epidemic situation caused by the new coronavirus delta mutant strain and further improve the implementation capacity of all-staff nucleic acid testing organizations, the National Health Commission organized experts to combine with previous work practices to revise the "All-staff New Coronavirus Nucleic Acid Testing Organization Implementation Guidelines" , And formed the "Guidelines for the Implementation of the New Coronavirus Nucleic Acid Testing Organization for All Staff (Second Edition)" (available for download in the "Medical Administration and Medical Management" section of the National Health Commission website).
Which clearly:
It is necessary to actively respond to the new crown pneumonia epidemic, quickly and efficiently control the epidemic, standardize the work flow of nucleic acid testing organization, sampling, testing, and reporting for all employees, and coordinate the deployment of nucleic acid testing resources to improve the quality of nucleic acid testing.
For cities with a population of less than 5 million, the task of nucleic acid testing for all employees should be completed within 2 days, and if necessary, it can be guaranteed by the province (region, city) as a whole.
Cities with a population of more than 5 million should complete the task of nucleic acid testing for all employees within 3 days, and can apply for national support when necessary.
Relevant nucleic acid detection strategies: In the early stage of the epidemic, at least 3 rounds of full-staff nucleic acid testing should be carried out when the source of the risk is unknown; then, based on comprehensive research and judgments such as flow traceability, community containment control range, nucleic acid testing results, etc., determine the scope of subsequent testing and frequency.
In principle, quarantine points and streets or communities where there have been cases in the past 3 rounds of nucleic acid testing should be checked every day, and streets or communities where there have been cases within 14 days but no cases in the past 3 rounds of nucleic acid testing should be checked every other day, and no cases have appeared in 14 days. The area can be inspected every 5 days.
Relevant sampling method: Determine the sampling method according to the control measures taken by the target population. Isolation points and other key populations should be single-checked and single-checked. Closed communities (closed to households) 1 household and 1 tube, and other areas adopt 5 mixed 1 or 5 mixed 1 or 1 tube according to actual conditions. 10 mixed 1 to carry out testing.
Regarding the storage and guarantee of nucleic acid testing laboratories: cities with a population of less than 5 million should reserve more than 2 laboratories or areas that can be used by the nucleic acid testing support team; cities with a population of more than 5 million should reserve more than 5 A laboratory or remodelable area used by the nucleic acid testing support team.
Each laboratory or remodelable area should be able to accommodate at least 5 testing teams (the daily testing volume of each team is calculated based on 10,000 tubes), and relevant testing equipment, reagents and consumables should be stocked.
