Chinanews.com, Beijing, January 20 (Chen Hang) Pang Xinghuo, deputy director of the Beijing Municipal Center for Disease Control and Prevention, stated at a press conference on January 19 that the Municipal Center for Disease Control and Prevention reported 2 cases in Daxing District on January 17. Whole-genome sequencing and analysis of new coronavirus samples from local confirmed cases.
The results suggest that the two cases of virus belong to the L genotype European family branch 1 (B.1.1.7), which is the same transmission chain.
The virus has no genetic association with the previously reported local cases and imported cases in Beijing, and has no genetic association with recent local cases in other provinces in China, and is highly homologous to the new coronavirus variants found in the UK.
After a review by the Chinese Center for Disease Control and Prevention, the two confirmed cases of virus are considered to be variants of the new coronavirus discovered in the United Kingdom, and the source of infection is initially determined to be imported from abroad.
The epidemiological relationship between subsequent cases in Daxing and other areas will be further investigated and demonstrated to clarify the intergenerational relationship between cases.
At present, the traceability of the local clustered epidemic situation in Daxing District is underway.
