The source of infection in Tianjin Hailian cold storage is North American pig head
At the press conference, Ms. Zhang Ying, deputy director of the Tianjin CDC, introduced the source of infection in Tianjin Hailian cold storage is North American pig head!
Crack! The source of infection in Tianjin Hailian cold storage is North American pig head. The first case of infection in Haixuan community had a cough in the elevator.
According to the Tianjin Epidemic Prevention and Control Press Conference, from 24:00 on November 24th, Tianjin will adjust Hangu Street in Binhai New Area and Central Fishing Port Cold Chain Logistics Zone A and B to low-risk areas. From 10:00 am on November 21st, Tianjin started the “Bincheng Screening”. By 10:00 pm on November 23rd, 2,467,411 nucleic acid samples were completed. The test results showed that all were negative.
Why is there no connection between Tianjin Hailian Cold Storage and Kanhaixuan’s epidemic?
At the press conference, Ms. Zhang Ying, deputy director of the Tianjin CDC, introduced that Hailian Cold Storage and Kanhaixuan’s epidemic are not related, and they are two independent cases. The basis of the judgment is not simply from the geographical location and personnel connections, but more importantly, the virus genes.
After rough sequencing, Hailian Cold Storage’s virus genes belong to the second branch of the European family of L genotype, and Kanhaixuan belongs to the first branch of the European family of L genotype. Their upper margins are the same, just like a family, they are two brothers. They are two different branches. From the genetic sequencing, it can be judged that the two epidemics are completely unrelated.
There is also a different mode of transmission. There has been no further human-to-human transmission in Hailian Cold Storage so far, only from material to person. In Kanhaixuan’s later period from material to human, other residents in the community were infected. This is also the difference between the two epidemics.
