(Fighting against new crown pneumonia) The Jiangsu, Zhejiang and Shanghai epidemic is the same related epidemic, experts analyze why port cities have repeatedly "broken defenses"

　　China News Service, Beijing, December 11th. Comprehensive news: The National Health Commission of China announced on the 11th that 87 new cases were confirmed in mainland China on the 10th, of which 36 were imported from abroad and 51 were local (35 in Zhejiang and 15 in Inner Mongolia) , 1 case in Yunnan).

There were 30 new cases of asymptomatic infections, of which 16 were imported from abroad and 14 were imported from China (13 in Zhejiang and 1 in Jiangsu).

　　As of 24:00 on the 10th, there are now 1,272 confirmed cases in Mainland China, a total of 4636 deaths, and a total of 99,604 confirmed cases have been reported.

There are 493 confirmed cases imported from abroad, and a total of 10,431 confirmed cases, with no deaths.

　　The epidemic situation in Mainland China is generally stable

　　On the 10th, there were 51 newly confirmed cases in mainland China, including 35 in Zhejiang Province, which surpassed Inner Mongolia for the first time in this round of the epidemic and became the province with the largest number of local confirmed cases in mainland China.

　　Wu Liangyou, deputy director of the National Health Commission's Disease Control Bureau, said on the 11th that the recent domestic epidemic has shown characteristics such as multiple transmission chains, partial spread and small-scale clusters, but the overall situation of the national epidemic is stable.

　　Wu Liang has a specific analysis and stated that the number of reported cases in Manzhouli, Inner Mongolia, has shown a fluctuating and declining trend, and the trend of the epidemic needs to be closely observed.

The risk of the epidemic in Harbin, Heilongjiang has been reduced. Tongliao City in Inner Mongolia, Qiqihar City in Heilongjiang, Shijiazhuang City in Hebei Province and Beijing have not seen new cases for more than 5 consecutive days.

The cases in Longchuan, Yunnan were all teachers and students from the same school. No related cases outside the school were found, and the epidemic has been basically controlled.

　　According to Wu Liangyou, the viral genome sequences of the epidemic cases in Shanghai, Zhejiang and Jiangsu are highly homologous, and they are the same related epidemic.

At present, the overall epidemic situation in Shanghai is relatively stable, with no new cases for 3 consecutive days.

The epidemics in Shaoxing, Ningbo, and Hangzhou in Zhejiang Province have developed rapidly, mainly involving families and crowd gathering places.

Currently, only a single case has been detected in Shaanxi, and no spread has occurred.

　　Shaoxing Shangyu implements comprehensive traffic control and control of Ningbo's first case, at least 4 generations of infected persons

　　Zhejiang Province added 35 local confirmed cases on the 10th, including 17 in Shaoxing City, 14 in Ningbo City, and 4 in Hangzhou City.

Zhejiang Province notified on the 11th that from December 5th to 15:00 on the 11th, a total of 98 local cases were reported in Ningbo, Shaoxing and Hangzhou, including 60 confirmed cases and 38 asymptomatic infections.

　　In order to resolutely stop the spread of the epidemic and curb the spread of the epidemic, since 1 pm on the 11th, the Shangyu District of Shaoxing, Zhejiang Province, which currently has the largest number of cases, has implemented comprehensive traffic control on roads, stations, waterways and other entrances and exits entering and leaving the area.

　　A press conference held in Ningbo on the evening of the 10th revealed that the city’s first case of the epidemic began on November 22, and at least four generations of infected persons have been transmitted-the case was first transmitted within the family and passed from family members to colleagues. Then a colleague caused multiple infections in a nursing center, and then the infected person in the center caused subsequent infections in the family and the community.

At present, the local spread of the epidemic in Zhenhai District, Ningbo is clear, and the trajectory of all infected persons is clear.

　　The Manzhouli epidemic is still in a stage of continuous development

　　On the 10th, 15 new local confirmed cases were confirmed in Inner Mongolia, of which 12 were in Manzhouli, Hulunbuir, and 3 were in Xinbarhu Right Banner.

From 0:00 to 14:00 on the 11th, Manzhouli City reported another 5 local confirmed cases.

As of 14:00 on the 11th, a total of 524 local confirmed cases have been reported in this round of the epidemic in Manzhouli City.

　　According to the latest report from the National Health Commission, the sequencing analysis of the viral genome of the Manzhouli epidemic showed that the epidemic was caused by a new overseas source and was not related to the previous epidemic in Inner Mongolia.

The epidemic first occurred in Manzhouli City, and then related cases were found in the two regional flags of Hulunbuir City and Tongliao City, as well as Qiqihar City and Harbin City in Heilongjiang Province, Shijiazhuang City in Hebei Province, and Haidian District in Beijing. It spread to 4 provinces. 6 places.

　　According to reports, the current Manzhouli epidemic is still in a stage of continuous development, and the number of reported cases has shown a fluctuating downward trend. The trend of the epidemic still needs to be closely observed.

　　Experts analyze why port cities repeatedly "break defense"

　　Since April 2020, more than 40 epidemics have occurred in mainland China, almost all of which are related to overseas imports.

The recent local clustered epidemics were imported from overseas through port cities.

Why port cities repeatedly "break defenses" have attracted much attention.

　　Liang Wannian, head of the expert group of the Leading Group for Epidemic Response and Handling Work of the National Health Commission, stated at a press conference on the State Council’s Joint Prevention and Control Mechanism on the 11th that the prevention and control of epidemics in port cities is difficult, mainly because of the large number of ports and borders in China and the number of points. The lines are long and wide, especially some land ports, which often lack natural barriers.

At the same time, some features of the new coronavirus have also increased the difficulty of prevention and control.

　　The first is that the new coronavirus can be transmitted through both humans and objects; second, many infected people have asymptomatic or atypical symptoms, which are difficult to identify and detect; third, there are many routes of transmission and are easy to achieve, such as through the respiratory tract and Contact transmission can also be spread through goods and cold chains; fourth, there are still many gaps in human understanding and understanding of the new coronavirus.

　　Wu Liangyou, deputy director of the CDC of the National Health Commission, believes that the “breaking prevention” in some port cities has also revealed that some local epidemic monitoring and warnings are not timely, the closed-loop management of high-risk personnel is not implemented, and regular nucleic acid testing is a mere formality. , Inadequate disinfection of transportation vehicles and related items, improper management of centralized isolation sites, and insufficient scientific and precise emergency response to the epidemic. In the future, we will need to fill in the weaknesses of port city prevention and control in many ways, and make scientific and accurate overseas imports. Prevention and control work.
