Which areas are involved?

  "The current epidemic situation shows a situation of multi-point sporadic and local large-scale outbreaks, which is caused by the characteristics of virus-causing strains and technological progress in prevention and control measures. The previous laws may not be applicable to the rebound of this wave of epidemics, and the duration may be longer than before. Some, it is not easy to make predictions." Recently, Zhang Boli, an academician of the Chinese Academy of Engineering, made a judgment on the current round of the epidemic in an interview.

  Except for Shanghai and Jilin, the risk of epidemic transmission still exists in Guangdong, Guangxi, Hebei, Shanxi, Jiangsu, Anhui, Fujian, Zhejiang, Henan and other places.

  Observing the data of infected people published in various places, the local scale outbreaks are prominent.

For example, the number of confirmed cases in Guangdong has continued to increase in recent days, mainly in Guangzhou, Shenzhen and Foshan.

Especially in Guangzhou, which accounts for more than 60% of Guangdong Province in terms of the number of newly infected people in the past seven days.

In the past seven days, Guangdong has added local infection data.

  In addition, Guangxi is mainly concentrated in Dongxing, Shanxi is mainly concentrated in Taiyuan Qingxu, Jiangsu is mainly concentrated in Suzhou, Hebei is mainly concentrated in Baoding and Handan, Zhejiang is mainly concentrated in Hangzhou and Ningbo, Fujian is mainly concentrated in Ningde and Quanzhou, Anhui is mainly concentrated in Fuyang and Chuzhou.

What is the risk of social transmission?

  Judging from the current data, there has not been a large-scale increase trend in many places.

No infected person was found in areas other than the prevention area, control area, and closed control area.

He also mentioned that the epidemic transmission index has dropped from 5.7 people at the beginning of the epidemic to 1.7 people.

  New outbreaks in many places have been dealt with quickly and effectively, and the risk of social transmission has been reduced under differentiated prevention and control measures by division and classification.

  Foshan Municipal Health Bureau announced on the 15th that the nucleic acid screening results in Foshan were negative for 4 consecutive days from the 11th to the 14th, achieving a dynamic social clearing.

  On the 14th, the sixth round of nucleic acid testing was completed in the main urban area of ​​Handan City, Hebei Province, and all social test results were negative.

There were 15 new cases of local asymptomatic infections that day, all of which were found at the isolation point.

  On the 14th, Ningde City announced that multiple rounds of nucleic acid tests have been carried out in the central urban area of ​​Ningde. Four counties (cities) of Fu'an, Fuding, Zherong and Zhouning have also carried out regional nucleic acid tests, and all the results have been negative.

  On the whole, the prevention and control measures in many places have been effective, but the epidemic situation is still severe and complex, with frequent cluster epidemics, and the risk of community transmission still needs to be vigilant.

  On the 14th, Chen Bin, deputy director and spokesperson of the Guangzhou Municipal Health and Health Commission, reported that clusters of epidemics have occurred in closed and semi-closed bars, Internet cafes and other places in Guangzhou.
