[Commentary] On July 26, the Information Office of the People’s Government of Xinjiang Uygur Autonomous Region held the ninth press conference on epidemic prevention and control. When reporting the latest epidemic situation and nucleic acid testing in Urumqi, it said that at present, most districts of Urumqi’s free nucleic acid testing work ( The county) has been basically completed. Starting today, Urumqi City will conduct a second free nucleic acid test in key areas such as Tianshan District, Shayibake District, and carry out "checking for omissions."

　　For people who have had close contact with confirmed cases and suspected cases, two nucleic acid tests are usually required to exclude them. For people who have been to high-risk areas in the epidemic area (situation), if they develop fever and respiratory symptoms, a negative nucleic acid test may have a false negative, so two nucleic acid tests are needed to rule out. In view of the above situation, for the health of the people of all ethnic groups in the city, starting today, we will conduct a second free nucleic acid test in key areas such as Tianshan District, Shayibake District, and carry out "checking for omissions."

　　[Explanation] According to Zhang Wei, from the experience of other regions in China, there are many factors that affect the results of nucleic acid testing, such as the sensitivity of the test reagent, the time of infection and detoxification of the tested person, and the cooperation of the tested person when the specimen is taken (poor cooperation It may result in the specimens not being taken in place), the testing environment, the operating proficiency of the inspectors, etc. For various reasons, false negative results can also occur in nucleic acid testing. The so-called false negative means that the tested person is indeed an infected person, but the nucleic acid test result is negative. Therefore, it is necessary to conduct secondary nucleic acid testing in Tianshan District and Shayibake District.

　　From 0:00 to 24:00 on July 25, there were 22 newly confirmed cases of new coronary pneumonia in Urumqi City (5 of them were asymptomatic infections transferred to confirmed cases), and 38 new asymptomatic infections were added. As of 24:00 on July 25, Urumqi City has 135 confirmed cases and 147 asymptomatic infections. The newly-added asymptomatic infections on the 25th were basically detected through the city's free nucleic acid test and active screening.

　　According to the report, the expert group of the State Council and the experts of the autonomous region and Urumqi city are making further assessments of the development of the epidemic based on the results of nucleic acid testing and epidemiological investigations.

　　At the same time, in order to ensure the effective, orderly and effective treatment of patients with new coronary pneumonia, the Autonomous Region Epidemic Prevention and Control Headquarters coordinated the efforts of all parties and established the Xinjiang Uygur Autonomous Region New Coronary Pneumonia Medical Treatment Designated Hospital on the basis of the Autonomous Region Infectious Disease Hospital. Under the guidance of the steering group of the control mechanism, a team of medical experts was formed, high-quality resources were mobilized, the diagnosis and treatment plan was improved, the diagnosis and treatment process was optimized, and the treatment was fully carried out.
