There has been no significant change in pathogenicity of the new coronavirus variant reported in the UK

recently, the Shanghai CDC in the United Kingdom imported new confirmed cases of coronary pneumonia genetic sequencing monitoring, found that one case of the new coronavirus gene sequence B.1.1.7 subsype, similar to the recently reported variant of the virus gene in the United Kingdom.
, director of the Cdc's Viral Disease Institute, was interviewed by a reporter from the main station.genetic tests of the mutant strains found in Shanghai showed that the mutant strains were more infectious to cells, but their spread was closely related to human social activities, winter climate and population self-protection measures.there is no difference in pathogenicity, severity or death rate between the new coronavirus variant strain and the previous variant strain, and there is no obvious change in pathogenicity, so there is no need to panic.has not yet found a new coronavirus variant in China's listed inactivated new coronary vaccine immune effectiveness.At present, China's mainstream nucleic acid diagnostic reagents are targeted at the new coronavirus dual-target gene, N gene and ORF1ab gene, protein gene variation does not affect the sensitivity and specificity of nucleic acid reagents, Shanghai variant is China's local nucleic acid reagent detection.China in April blocked the spread of the local new coronavirus, after the import of cases or contaminated cold chain items caused by more than 10 new coronavirus pneumonia cluster outbreaks, have taken effective measures to stop transmission. Regular screening of high-risk groups, early diagnosis, early treatment, early isolation of infected persons and close contacts, wearing masks, washing hands regularly, maintaining social distance, is an effective measure to stop the spread of the new coronavirus in China.people need not panic, we must strictly implement China's existing prevention and control measures, the need to strengthen personal awareness of protection, especially for imported cases of hospitals or designated isolation hotels of health care and staff protection.
