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).

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.

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.

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.

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.
