What is the spread of this mutant strain of the new coronavirus that appeared in the UK? How should the public respond? Xu Wenbo, director of the Institute of Viral Diseases at the Chinese Center for Disease Control and Prevention, responded to this.
No difference in severity of pathogenicity or mortality
According to the Xinhua News Agency, the Shanghai Municipal Center for Disease Control and Prevention announced on day 1 that the center recently sequenced the genome of a confirmed case of a new coronary pneumonia imported from the United Kingdom, and found that the genetic sequence of the The novel coronavirus in one case was similar to a recently reported mutant virus in the UK. What is the spread of this mutant strain of the new coronavirus that appeared in the UK? How should the public respond? Xu Wenbo, director of the Institute of Viral Diseases at the Chinese Center for Disease Control and Prevention, responded to this.
Q: Has the spread of the new coronavirus variants discovered in Shanghai in the UK increased among the population?
Xu Wenbo:The results of the genome sequencing of the mutant strain showed that the mutant strain has improved cell infectivity, but its spread between humans is closely related to human social activities, winter weather, and population self-protection measures.
Question: Has the virulence and severity of the mutant strain increased?
Xu Wenbo:At present, there is no difference in pathogenicity, severity, or mortality rate between the mutant strain and the previous mutant strain, and the pathogenicity has not changed significantly, so there is no need to panic.
Question: Does China’s new coronavirus vaccine have immune protection against this mutant strain?
Xu Wenbo:At present, the mutant strain has not been found to have an impact on the immunological efficacy of the new inactivated coronavirus vaccine marketed in China.
Question: Can the nucleic acid detection reagents of the novel coronavirus from China detect this mutant?
Xu Wenbo:At present, the main nucleic acid detection reagents in China are targeting the dual target genes of the novel coronavirus, namely the N gene and the ORF1ab gene. Mutation of the protein S gene of this new variant in the UK does not affect the sensitivity and specificity of the nucleic acid reagent. Shanghai Recently Newly Found Mutant Is China’s Native Nucleic Acid ReagentDetected.
Question: Are existing measures in China effective in preventing and controlling the spread of the new coronavirus?
Xu Wenbo:China basically blocked the spread of the new local corona virus in April 2020. For more than a dozen new clusters of corona pneumonia subsequently caused by imported cases or contaminated elements of the cold chain, effective measures have been taken to stop the spread. Regular detection of high-risk groups, early diagnosis, early treatment, early isolation from close and infected contacts, as well as the use of masks, frequent hand washing, and maintaining social distancing are effective measures to stop the spread of the new coronavirus in China.
Question: What other measures should be taken in response to the emergence of mutant strains of the new coronavirus?
Xu Wenbo:People don’t need to panic. They must strictly implement the prevention and control measures existing in our country and strengthen awareness of personal protection, especially strengthening the protection of medical personnel and professionals in hospitals or hotels designated in quarantine with imported cases.
