The three chains of transmission of patients diagnosed in Haidian, asymptomatic infected people in Chaoyang, and positive people in Fangshan-Fengtai are independent of each other and do not intersect. Among them, there are both Ami kerong infection and Delta infection.

This round of outbreaks first appeared in Haidian.

The source of the first chain of transmission may come from international mail

On January 15, a new locally confirmed case was added in Beijing, and the virus gene sequencing detected the specific mutation site of the Omikerong strain. The case is currently living in Boya West Garden, Shangdi Street, Haidian District, developed pharyngeal discomfort on January 13, nucleic acid testing was carried out on January 14 due to the requirements of unit epidemic prevention and control, and the nucleic acid test result was reported positive on January 15.

Around January 14, there were cold symptoms, on the 17th to the Chaoyang District nucleic acid testing point for nucleic acid testing, the nucleic acid test result was positive on the 18th, the disease control department immediately contacted the person after receiving the positive report of the initial screening, and timely implemented control on the G1085 train that was about to run to Weihai.

Among them, 4 people are the same unit cold storage stevedores, the other 1 is a close connection with the same household, engaged in cold storage loading and unloading work together, and 3 people were detected to be specific mutation sites of Delta mutant strains.

Beijing: Carry out comprehensive inspection and screening of the city's cold chain industry as soon as possible

At the press conference, Xu Hejian, spokesman for the Beijing Municipal Government, said that it is necessary to further strengthen the supervision of the whole chain of cold chain food, carry out comprehensive inspection and screening of the city's cold chain industry as soon as possible, cold chain epidemic prevention cannot be taken lightly, further strengthen the supervision and risk prevention and control of cold chain food, compact the main responsibility of production and operation enterprises, strictly disinfect cold chain food and packaging, do not disinfect and do not enter the warehouse, do not check the nucleic acid, encrypt the frequency of employee goods and environmental nucleic acid testing, ensure that no one is missed, and no blind spots are left. Strengthen the normalization of the city's cold storage supervision, improve the traceability system of the warehouse, check the responsibility for unclear sources and incomplete bills, strictly prohibit mixed transportation and mixed storage with domestic food, and seriously deal with violations of laws and regulations such as concealing the source and impersonating domestic food storage and sales.
