(Fighting against New Coronary Pneumonia) Wuhan "Re-Zero" Review: Adjusting Risk Level to Carry out National Nucleic Acid Test
China News Agency, Wuhan, June 5 (Reporter Zhang Qin) The Wuhan Municipal Health Commission announced on the 5th that the city's last three patients with new coronary pneumonia were discharged. This is after the resettlement of patients with new coronary pneumonia in the hospital in Wuhan on April 26, the resettlement of local patients with new coronary pneumonia in the hospital again means that the confirmed cases in Hubei Province are cleared.
On June 3, at the Wuhan Pulmonary Hospital, the last three patients with new coronary pneumonia who were hospitalized for more than 24 hours had negative nucleic acid test results. The body temperature was normal and the symptoms disappeared. On June 4th, as assessed by the National Expert Group, all three patients met discharge criteria.
According to the report, as of 24:00 on June 1, Wuhan Dongxihu District has not reported new confirmed cases of new coronary pneumonia for 14 consecutive days. According to the national grading standards for the New Coronary Pneumonia Epidemic Division, from 0:00 on June 2, the East-West Lake District was adjusted from a medium-risk area to a low-risk area. So far, all districts in Wuhan are low-risk areas.
Since the outbreak of the New Coronary Pneumonia epidemic, Wuhan was once the main battlefield for epidemic prevention and control. As of June 3, the city has reported a total of 50,340 confirmed cases. In mid-February, the peak number of new coronary pneumonia patients treated in the hospital in Wuhan reached 38,000.
Through the joint efforts of Wuhan and the national medical personnel who assisted Hubei, on March 13, Wuhan saw the first "zero addition" of suspected cases; on March 18, Wuhan saw the first "zero addition" of both suspected cases and confirmed cases; April 23 On Sunday, all the critical cases of new coronary pneumonia in Wuhan were cleared; on April 24, the serious patients with new coronary pneumonia in Wuhan were cleared; on April 26, the patients with new coronary pneumonia in Wuhan were reset.
From April 4th to May 8th, Wuhan has maintained zero new confirmed cases. After 14 consecutive days of no new confirmed cases, on April 18, the overall risk level of the Wuhan epidemic was classified as a low-risk area. However, starting from May 9, Wuhan City has successively reported 7 confirmed cases, among which there are many cases of asymptomatic infections converted to confirmed cases.
According to the national grading standard for the new coronary pneumonia epidemic, according to the evaluation of the experts, the Dongxihu District of Wuhan City, where there are confirmed cases, was adjusted to a medium risk level. Newly diagnosed cases of new coronary pneumonia appeared continuously, and from the same community, sounded the alarm of Wuhan epidemic prevention and control again. Due to poor control and management, the CPC Dongxihu District Committee decided to remove Zhang Yuxin from the position of secretary and member of the Qingjie Working Committee of the CPC Dongxihu District Committee. At the same time that the community where the confirmed cases were found was fully enclosed and hard-separated, Wuhan began to deploy national nucleic acid testing to further figure out the number of asymptomatic infections.
On June 2, Wuhan City released the results of the national nucleic acid test: from 04:00 on May 14 to 24:00 on June 1, Wuhan City concentrated 98998828 people and found no confirmed cases; 300 asymptomatic infections were detected The detection rate was 0.303/10,000, and 1174 close contacts were tracked. The results of nucleic acid tests were all negative. Both asymptomatic infections and close contacts were medically isolated.
The results of this concentrated nucleic acid test showed that at present, asymptomatic infections in Wuhan account for a very low proportion of the entire population, and no cases of asymptomatic infections infecting others have been found.
At a news conference on the prevention and control of the New Coronary Pneumonia Epidemic in Hubei Province held on the 2nd, Li Lanjuan, a member of the high-level expert group of the National Health and Health Commission and an academician of the Chinese Academy of Engineering, accepted that in addition to the number of children under 6 years of age, nucleic acid testing in Wuhan City Full coverage is extremely rare in the world. Judging from the analysis of the test data, "Wuhan is safe, Wuhan people are healthy."
Regarding the results of this nucleic acid investigation, Feng Zijian, an expert from the Liaison Group of the Joint Prevention and Control Mechanism of the State Council and the Deputy Director of the Chinese Center for Disease Control and Prevention, said: "The number of asymptomatic infections or those with positive nucleic acid tests is very small, which also means that The spread of the new coronavirus is basically close to being blocked."
