According to the National Health Commission, at 0-24:00 on March 11, 31 provinces (autonomous regions and municipalities directly under the Central Government) and the Xinjiang Production and Construction Corps reported 476 new confirmed local cases and 1,048 cases of local asymptomatic infection.
Since March, the current round of domestic epidemic has shown a multi-point sporadic and localized clustering trend, which has affected more than 20 provinces (autonomous regions and municipalities directly under the central government) across the country, and the cases reported in many places are All Omikerong variants.
The most obvious feature of this round of outbreaks is the large number of asymptomatic infected people. The number of indigenous asymptomatic infected people has exceeded the number of confirmed cases for 6 consecutive days. Among the new local cases yesterday, asymptomatic infected people accounted for nearly 70% of the total number of infected people, and this proportion was higher in some provinces and cities, and even reached more than 90% in Shanghai and Gansu Provinces.
Under the epidemic situation, prevention and control measures in various places have suddenly escalated. Yesterday afternoon, Changchun city's communities (villages) and units implemented closed management; in the early morning of March 12, Shenzhen's "10+1" district issued a notice to suspend dine-in for all meals and shut down closed places that were not necessary for daily life...

Campus outbreaks have occurred in many places
In this round of epidemics, Qingdao Laixi, Chongqing, Kunming, Jilin and Changchun have all experienced campus epidemics.
Among the new local positive cases yesterday, Shandong Province had the largest number of new cases, reaching 559 cases (159 cases were confirmed in the local area and 400 cases of local asymptomatic infection).
As of March 11, there were local confirmed cases of COVID-19 in 8 cities in Shandong Province: Qingdao, Weihai, Binzhou, Yantai, Dezhou, Zibo, Rizhao and Weifang.
Among them, Qingdao is the epicenter of the current round of Shandong epidemic, and the first locally confirmed case was reported on March 1. On March 4, a campus cluster outbreak occurred in Laixi, Qingdao.
Qingdao City previously reported at the epidemic prevention and control press conference that the campus epidemic was found in the fever clinic staff on March 4, and the 3 confirmed patients were Laixi No. 7 middle school students, and the infection was all Aomi Kerong mutant strains.
After the control of Laixi Vii, some confirmed cases were found among the close contacts of the three students. On March 5, Qingdao held a press conference on epidemic prevention and control, informing that the epidemic has been hidden in the school for a period of time, and because it is a day school, the risk of community transmission caused by the infection of students after infection affects family members is greater.
After that, students, their families and other associated infected people were quickly diagnosed one by one. As of 12:00 on 12 March, the Cumulative Number of Confirmed Cases (5 of which are cases associated with the Lacey Outbreak) and 960 cases of asymptomatic infection (of which 6 are cases associated with the Laixi Outbreak) have been reported. Among the confirmed cases, there are 320 cases of students, 41 cases of teachers, and 168 cases of key groups. As of today, the source of the epidemic in Qingdao Laixi is still not clear.

In addition, in the early morning of March 12, Chongqing High-tech Zone reported 3 local confirmed cases of new crown pneumonia, all three of whom were students of Chongqing Urban Management Vocational College. As of 12 o'clock today, the first round of nucleic acid testing has been carried out for 323 people in Chongqing and the second close contact, and 122 people have produced results, of which 8 people have been positive for the initial screening, all of whom are students of Chongqing Urban Management Vocational College. Of the seven new infections in Kunming on March 10, six were students of the Yunnan Academy of Arts, which had previously been confirmed to be infected by 5 students, and 11 of whom had been infected with COVID-19.
Since March 6, Jilin Agricultural Science and Technology College has reported the detection of infected people for five consecutive days, and on March 7, five asymptomatic infected people are students of Jilin Agricultural Science and Technology College. On March 8, the number of infected people in the school surged, with 14 confirmed cases and 43 asymptomatic infected people located in the university dormitory, and seven more positive cases were added in the two days of March 9 and March 10.
According to the "Caixin Network" news, a middle school in Changchun City is now a "super communicator". On March 11, Jilin Province reported that there had been community transmission of the epidemic in Jiutai District, and Caixin reported that the "case 4" associated with Jiutai Yizhong was a "super spreader" of community transmission.
According to the circulation data, there has been an intersection between "case 4" and the "patient zero" of the current round of the epidemic in Changchun City. Since then, "Case 4" has traveled to Jiutai No. 1 High School several times and infected 38 confirmed people in the following 5 days. As of 21:00 on March 11, Changchun announced a total of 78 confirmed cases in this round of epidemic, which is directly related to "case 4" and nearly half of the confirmed cases.
According to the "Caixin" report, in addition to the nine tai and one middle school, other local middle schools have also experienced campus epidemics. Among the confirmed cases announced since March 8, there are cases of Jiutai Experimental High School. Wang Mou, a sophomore at the school, told caixin reporters that he was diagnosed on the evening of March 9, and the class group also informed him that another classmate in his class was diagnosed.
Due to the ineffective epidemic prevention of the campus, a number of major leaders of the Qingdao Laixi Municipal Party Committee and the Municipal Government, as well as leaders of the epidemic-related schools and other relevant cadres, a total of 17 people were punished; the mayor of Jilin City, the mayor of Jiutai District of Changchun City, and the secretary of the party committee of Jilin Agricultural Science and Technology College were also dismissed.

At 0-24:00 on March 11, there were 29 new cases in Shenzhen, of which 27 were locally confirmed cases and 2 were asymptomatic infected people. On the morning of the 12th, Shenzhen's "10+1" district issued a notice that all restaurants and dine-in meals were suspended, non-essential places of life were closed, and non-essential personnel of government agencies, enterprises and institutions worked at home for 5 days in principle.
Among them, the five districts of Futian, Luohu, Nanshan, Yantian and Bao'an in Shenzhen should be "checked once a day" for 4 consecutive days, and "24-hour nucleic acid negative" or sampling records on the same day are required for entering and leaving public places.
In addition, epidemic prevention and control measures for primary and secondary schools are also being strengthened. From March 12, all primary and secondary schools in Shanghai will be adjusted to online teaching, kindergartens and nurseries will stop children from entering kindergartens, and all kinds of training institutions and childcare institutions will not be allowed to carry out offline training and childcare services.

Regarding the characteristics of this round of epidemic prevention and control and whether or not Aomi Kerong can "lie flat" and other issues, Zhang Wenhong, director of the National Infectious Disease Medical Center and head of the Shanghai New Crown Pneumonia Clinical Treatment Expert Group, expressed his views. "I don't agree with 'lying flat', if the epidemic is allowed to spread, then the result may pay a relatively high death price."
Zhang Wenhong believes that the overall strategy of the current fight against the epidemic is to "accumulate small victories into big victories", although a small number of people may be at home, but most people still maintain normal work. Although some units will be closed in the near future for various reasons, the ways and methods of closure need to be broken through for the future.
When talking about the future anti-epidemic work, Zhang Wenhong said that the fight against the epidemic not only achieves the "zero" of the social aspect, but also maximizes the impact of the city or the environment in which it lives, the degree of shutdown is smaller, and the number of people under control is a little less, so that progress has been made.
