Thirty-four Manzhouli epidemic viruses in middle-high-risk areas in Mainland China are Delta mutants

  On the 4th, there were 75 newly confirmed local cases in Mainland China. They were from Inner Mongolia (61 cases, all in Hulunbuir), Heilongjiang (5 cases, all in Harbin), Hebei (4 cases, all in Shijiazhuang), Yunnan (4 cases, all in Shijiazhuang), Cases, all in Longchuan County, Dehong Prefecture), Guangdong (1 case, in Guangzhou City).

  With the gradual expansion of the scope of the epidemic, the number of medium- and high-risk areas in Mainland China has increased to 34.

Among them, there are 8 high-risk areas, 7 in Manzhouli City, Inner Mongolia, and 1 in Longchuan County, Yunnan Province.

There are 26 medium-risk regions, distributed in Guangzhou City in Guangdong Province, Harbin City in Heilongjiang Province, Dehong Prefecture in Yunnan Province, Shanghai City, and Hulunbuir City and Tongliao City in Inner Mongolia.

  In Inner Mongolia on the 3rd, there were 61 newly confirmed local cases, all of which were reported by Hulunbuir, including 58 cases in Manzhouli City and 3 cases in Xinbarhu Right Banner.

According to the latest news, Manzhouli City added 17 local confirmed cases and 3 asymptomatic infections from 0-14 on the 4th.

As of 14:00 on the 4th, Manzhouli City had reported a total of 314 local confirmed cases in this epidemic, surpassing Dalian City, becoming the region with the most local confirmed cases in Mainland China since the local epidemic occurred on October 17.

  Manzhouli City notified on the 4th that after genetic sequencing, all the new coronaviruses infected by the confirmed cases in Manzhouli belonged to the Delta mutant strain, which is "a new import of new coronaviruses overseas through people or things."

It is preliminarily speculated that the source of infection in Shijiazhuang cases is Manzhouli, with 15 cases associated with Manzhouli in Harbin City

  After 18 consecutive days of zero new local cases, Hebei Province reappeared 4 local confirmed cases on December 3, all from Shijiazhuang City.

  Shijiazhuang City notified on the 4th that all the new cases were workers at an electronic construction site in Luquan District. The 4 persons were a couple and a mother and child. The home addresses were all in Qiqihar City, Heilongjiang Province.

Liu Moumou reported coughing for three days, and his chest CT showed clinical signs of new coronary pneumonia.

Therefore, it is preliminarily speculated that Liu Moumou was the source of infection for this local confirmed case in Luquan District, and further confirmation will be made after the gene sequencing results come out.

  In Harbin, Heilongjiang Province, 5 local confirmed cases were added on the 3rd, all of which were discovered during the intensive isolation and observation period, and they were Manzhouli-related cases.

  Shanghai reported on the 4th that the 2 local confirmed cases reported in Shanghai on the 2nd were due to a mother-daughter relationship.

After genetic sequencing by the Shanghai Centers for Disease Control and Prevention laboratory, the two infected with the virus were mutant strains of Delta. The source of their infection does not rule out the possibility of exposure to an environment contaminated by imported viruses abroad.

  Guangzhou City held a press conference on the 4th and stated that the city had an additional local confirmed case on the 3rd, which was an inbound quarantine hotel worker.

The gene sequencing results showed that the infection of the Delta mutant strain was highly homologous to a positive case in the hotel, and it was the same chain of transmission.

The results are highly homologous and belong to the same transmission chain. They are all Delta mutant strains and are not related to the previous Dehong prefecture and the domestic epidemic.

Dalian's global low-risk official requires continued digging and thorough investigation
