  China's official analysis on why this round of epidemics is so many, wide-ranging and frequent

  On the 17th, there were 2,388 new local confirmed cases in mainland China, more than 1,000 cases for 6 consecutive days, and a substantial increase from the previous day (1,226 cases).

The new local confirmed cases were distributed in 21 provinces on the same day, and Jilin Province still ranked first with 1834 cases, followed by Fujian with 113 cases.

Eleven other provinces reached double digits: 74 in Guangdong, 61 each in Tianjin and Shandong, 57 in Shanghai, 46 in Liaoning, 33 in Shaanxi, 24 in Hebei, 16 each in Heilongjiang and Gansu, 13 in Zhejiang and 10 in Chongqing. example.

  The new local asymptomatic infections that day involved 20 provinces, including Jilin (792 cases), Shanghai (203 cases), Hebei (193 cases), and Shandong (162 cases) over 100 cases.

  China's National Health Commission said on the 18th that China's current round of epidemics is characterized by multiple, wide-ranging and frequent occurrences. First, because the global epidemic is at a high level, the pressure of overseas imports has surged; The BA.2 sub-branch is more contagious and concealed, which makes early detection difficult; third, large-scale movement of people during the Spring Festival, as well as increased gathering activities such as conferences, training, weddings, funerals, and marriages, have become the "spreaders" of the epidemic. "Amplifier"; Fourth, some places believe that the Omicron variant has mild symptoms, lax thinking and paralysis, resulting in insufficient preparation in all aspects.

  Relevant experts analyzed and judged that the current round of the global epidemic is a high epidemic and will not end in the near future.

China will continue to face the situation of epidemic prevention and control, which is dominated by the Omicron virus strain in many places at the same time.

At the same time, the recent epidemic in many places has multiple transmission chains, and the source of the epidemic is complicated, which has brought great challenges to the traceability and prevention and control work.

  Jilin Epidemic Shows High Aggregation, Shanghai Epidemic Distributed at Multiple Points and Multiple Chains Parallel

  From March 1 to 17, Jilin Province has reported more than 14,000 local infections.

  Jilin Province held a press conference on the 18th, saying that at present, the epidemic situation in Jilin is still severe and complicated.

The epidemic has shown a high degree of aggregation, among which school aggregation, rural aggregation, and social unit aggregation are the most significant, increasing the risk of the epidemic in some areas.

  According to reports, Jilin Province has banned the flow of people from the province across provinces and cities (states), and all primary and secondary schools and kindergartens have been suspended.

Non-essential non-flow has greatly reduced the risk of epidemic spread and spillover, and the risk of a short-term surge in the number of infected people due to clustered epidemics has been effectively controlled.

  The Shanghai Municipal Health Commission introduced on the 18th that since March, the local epidemic situation in Shanghai has been characterized by multi-point distribution, multi-chain parallel, and hidden transmission. This epidemic is also the most severe since Shanghai entered normal epidemic prevention and control. The task of continuing the dissemination is enormous.

  On the 17th, Shanghai added 57 new local confirmed cases and 203 asymptomatic infections, all of which increased significantly from the previous day.

In this regard, the Shanghai Municipal Health Commission stated that two days ago, Shanghai started nucleic acid screening in key areas, and these cases were mainly found from active screening.

The preliminary results of this screening show that the epidemic has the characteristics of regional clustering, and some hidden infections and transmissions have also been found.

Through this screening, a good foundation has been laid for timely blocking of local outbreaks and wider social spread.

  The stage effect of epidemic prevention and control in Shandong has been consolidated, and there are nearly 500 local cases in Quanzhou, Fujian.

  Shandong Province announced on the 18th that the province added 61 local confirmed cases and 162 asymptomatic infections on the 17th, mainly from key groups in the isolation and control area.

At present, the phased effectiveness of epidemic prevention and control in Shandong Province has been further consolidated.

  According to reports, as the area with the most severe epidemic in Shandong, in the new round of nucleic acid testing in Laixi, Qingdao, no positive infected persons were found in the closed area, control area, and prevention area.

The reported cases in Zibo, Weihai and other places are all people in the isolation control area, and the risk of social transmission has been effectively controlled.

Binzhou's newly confirmed cases (31 cases) and asymptomatic infections (91 cases) increased significantly on the 17th. The local area has adopted strict control measures, and the overall epidemic situation is controllable.

  Quanzhou City, Fujian Province added 111 local confirmed cases and 81 asymptomatic infections on the 17th. From the 13th to 10:00 on the 18th, a total of 492 local cases (311 confirmed cases and 181 asymptomatic infections) were reported.

All confirmed cases reported since March 15 were found in centralized quarantine personnel, and the risk of community transmission of the epidemic was under control.

  Baoji City officials said on the 18th that a new round of large-scale nucleic acid screening samples in Jintai District, Weibin District, and High-tech Zone sampled nearly one million people, and no mixed tube positive was detected. The city's 20 new confirmed cases on the 17th were mainly due to Screening found from quarantine points.

  Shenyang City, Liaoning Province added 4 local confirmed cases and 12 local asymptomatic infections on the 17th.
