(Fighting against New Coronary Pneumonia) Chinese official: Since March, the cumulative number of local epidemics has reported more than 29,000 cases

  China News Service, Beijing, March 19 (Reporter Li Chun) Lei Zhenglong, deputy director and first-level inspector of the CDC of China's National Health Commission, said in Beijing on the 19th that from March 1 to 18, the cumulative number of local epidemics in China More than 29,000 cases of infected people have been reported, affecting 28 provinces. Overall, the local epidemic in China is still in the developing stage.

  The joint prevention and control mechanism of the State Council of China held a press conference on the same day. In response to the current epidemic situation in China, Lei Zhenglong said that the current fourth wave of the new crown epidemic in the world is still operating at a high level. From March 1 to 18, the cumulative report of the local epidemic situation in China More than 29,000 cases have been infected, affecting 28 provinces, of which more than 10,000 cases have been reported in one province in Jilin Province.

Four other provinces have cumulatively reported more than 1,000 cases, and 10 provinces have cumulatively reported between 100 and 1,000 cases.

  Lei Zhenglong pointed out that, in general, the local epidemic situation in China is still in the developing stage, and many provinces are facing the prevention and control of the Omicron epidemic in many cities at the same time.

The comprehensive team of the Joint Prevention and Control Mechanism of the State Council continues to guide the epidemic-stricken areas to strictly implement various prevention and control measures, quickly conduct nucleic acid screening, quickly conduct flow investigation and traceability, timely standardize centralized isolation, strict community management and control, and timely regional investigations, so as to realize the social aspect as soon as possible. The "dynamic clearing" of the epidemic will resolutely hold the bottom line that the epidemic will not rebound on a large scale.

  In response to the rapid increase in the number of cases at this stage, the key points and difficulties of domestic epidemic prevention and control, Wu Zunyou, chief epidemiologist of the Chinese Center for Disease Control and Prevention, pointed out that the focus of prevention and control work is in two aspects: First, for the epidemic situation that has occurred It is necessary to cut off the transmission as soon as possible to prevent the spread and prevent the spread of the disease in the areas where there is no epidemic; the second is to prevent the occurrence of new epidemics in the areas where the epidemic has not occurred, especially in places with relatively concentrated personnel, such as schools, prisons, nursing homes and other densely populated places. .

  He pointed out that the difficulty of prevention and control work is how to detect all infected people in time. The first is "timely", and we must catch the virus before it spreads.

The second is "all". In the entire transmission chain, all people who may be infected must be discovered to avoid omissions. Missing cases may be the source of a new transmission chain.

  Wu Zunyou said that at present, some new technologies can help to detect infected people in time, including the application of big data and timely and comprehensive nucleic acid detection.

He said, "When we carry out full-staff testing in a certain local area, it must be completed in a short period of time. It is best to complete a round of testing within 1 to 3 days, and it must be fast."

  Wu Zunyou pointed out that in general, 3 to 4 rounds of nucleic acid screening within the designated range can basically achieve zero cases at the social level. He emphasized that we must pay attention to prevent omissions, and it is very important to be timely, fast and comprehensive.

  In addition, Wu Zunyou pointed out that asymptomatic infections or mild cases found, should be managed in some centralized isolation places, and certain medical personnel should be allocated to ensure that patients with aggravated symptoms are transferred to designated hospitals for treatment in a timely manner.

  "If we do all these tasks well, it will be very helpful for prevention and control work and timely control of the epidemic." Wu Zunyou said.
