[Explanation] On August 14, Xinjiang held the 28th press conference on epidemic prevention and control. Wen Guoxin, deputy director of the Urumqi Center for Disease Control and Prevention, introduced that the epidemic spread quickly. Within the first 14 days, confirmed cases The number of asymptomatic and asymptomatic infections has increased rapidly; at the same time, there are many mild and asymptomatic infections, and the detoxification of some patients is relatively late, which brings greater difficulty to the prevention and control work.

  He introduced that the incubation period of the new coronavirus is usually 3 to 7 days, which means that most people will get sick within 3 to 7 days after being infected with the virus, some people are less than 3 days, and some people are more than 7 days, but basically They are all within the 14-day incubation period and require repeated testing to find out. Two consecutive nucleic acid tests were negative, mainly for two reasons.

  One is that after the new coronavirus infection, the virus mainly inhabits the lungs, and the inflammation produced blocks the lung airways, and the virus cannot be excreted temporarily, and there are very few nasopharyngeal viruses, so it is difficult to collect the virus. The second is the change of the condition and the timing of sampling. The progress of the patient's condition is different. The timing and time interval of sampling will also affect the test results and cause false negatives.

  [Explanation] According to the official website of the Xinjiang Health Commission, as of 0:00 to 24:00 on August 13th, 8 new cases of new coronary pneumonia were confirmed in Xinjiang; 4 new cases of asymptomatic infection were added, and 0 cases were converted to confirmed cases that day.

  According to the seventh edition of the new coronavirus diagnosis and treatment plan, the interpretation of nucleic acid test results cannot rely solely on laboratory results. It must be combined with epidemiological history and clinical manifestations to make comprehensive judgments. If there is a clear epidemiological exposure history and clinical symptoms, one or two nucleic acid tests are negative, it cannot be simply determined as non-infected, it may be false negative, and repeated sampling and testing are required. If you have not been to a high-risk area where the new coronary pneumonia is prevalent, and if you have a history of contact with an infected person, and have no clinical symptoms such as fever or sore throat, the nucleic acid test result is negative, there is no need to worry about false negatives.

  In the notification, Zhang Wei, director of the Urumqi Municipal Health Commission, said that during the epidemic, in order to fully meet the needs of the people for basic medical services and ensure that patients with acute and critical illness can receive timely treatment, Urumqi has specifically designated 28 designated hospitals for the treatment of acute and critical patients. Further strengthen overall coordination, multi-party linkage, implement industry supervision, implement the first-diagnosis responsibility system, and achieve seamless connection, joint prevention and joint governance. At the same time, implement the complaint management system and regulate and supervise from the source.
