(Fighting against New Coronary Pneumonia) China's National Health Commission: Controlling the epidemic as soon as possible can reduce the number of nucleic acid testing rounds

  China News Agency, Beijing, May 19. According to Chinese official media on the 19th, the relevant person in charge of the National Health and Health Commission explained the issues related to nucleic acid testing.

He said that if it is not possible to "do all the tests that should be checked" and "turn all the necessary transfers", more rounds of nucleic acid tests will have to be used to find out the infected.

  Talking about why multiple rounds of nucleic acid testing were carried out in areas where the epidemic occurred, the person in charge said that currently, China's epidemic prevention and control has entered a new stage of responding to the epidemic of the mutant strain of Omicron virus.

The Omicron variant has the characteristics of faster spread, shorter incubation period, and stronger concealment. It must be processed quickly and effectively cut off the virus transmission chain in order to achieve the maximum prevention and control effect with the minimum cost.

  In the event of a clustered epidemic, especially when the source of risk is unknown, nucleic acid testing of the population in the designated area must be completed within a specified time.

After the screening of the population is completed, based on the number of infected persons and their distribution, etc., the risk of epidemic prevention and control will be studied and judged, and then the next round of nucleic acid testing will be decided.

  The person in charge pointed out that the number of nucleic acid testing rounds can be reduced only if the "examination should be checked" as soon as possible, the infected persons and close contacts should be "turned as far as possible", the source of infection should be discovered in time, the transmission route should be cut off, and the epidemic should be controlled as soon as possible. In order to "do all the tests that should be checked" and "turn all that should be done," more rounds of nucleic acid testing will have to be used to find out the infected.

  Regarding the normalization of nucleic acid testing in areas where no epidemic has occurred, the person in charge said that normalized nucleic acid testing in areas where there has not yet been an epidemic but a high risk of importation will help improve the sensitivity of epidemic monitoring and early warning. , detect potential risks earlier, and better implement the "four early" requirements; at the same time, it is conducive to providing more convenient and efficient nucleic acid testing services for people who "should be tested" and "willing to be tested".

Therefore, all localities can carry out normalized nucleic acid testing according to the needs of local epidemic prevention and control.

  The person in charge also said that in the normalization of epidemic prevention and control, nucleic acid testing should be carried out in accordance with the requirements of key groups "should be checked" and other groups "willing to check", especially in provincial capital cities and cities with a population of 10 million. The establishment of a 15-minute walk for nucleic acid "sampling circle" aims to facilitate people to conduct nucleic acid sampling nearby for "early detection" and to improve the sensitivity of epidemic monitoring and early warning.

  He also pointed out that normalized nucleic acid testing is determined according to the needs of local epidemic prevention and control, and not all cities are required to establish a 15-minute nucleic acid "sampling circle", mainly concentrated in provincial capital cities and cities with a population of 10 million with high import risk; Not all people are required to be tested every 48 hours, and the specific testing frequency will be determined by the local area based on the development of the epidemic situation and the needs of prevention and control, as well as the situation.
