    Shanghai CDC announced on the 1st, the center recently entered the United Kingdom of new confirmed cases of coronary pneumonia genome sequencing, found that one case of the new coronavirus gene sequence and recently reported in the United Kingdom mutated virus gene similar. How spread is this new coronavirus variant in the UK? How should the public respond? Xu Wenbo, director of the CDC's Viral Disease Institute, responded.
    : Has the new coronavirus variant found in the UK been found in Shanghai increasing its spread in the population?
    : The genome sequencing results of this mutant strain show that the mutant strain is more infectious to cells, but its propagation is closely related to human social activities, winter climate and population self-protection measures.
    question: Has the virus-like strength and severity of this variant increased?
    Wenbo: At present, there is no difference in pathogenicity, severity or death rate between the mutant strain and the previous variant strain, and there is no obvious change in pathogenicity, so there is no need to panic.
    question: Is China's new coronavirus vaccine immune to this variant?
    : The mutant strain has not yet been found to have an effect on the immune ability of China's listed inactivated new coronavirus vaccine.
    question: Can the new coronavirus nucleic acid testing reagent detect the mutant?
    Xu Wenbo: At present, China's mainstream nucleic acid detection reagents are targeted at the new coronavirus dual target gene, namely N gene and ORF1ab gene, the emergence of this new variant of the S protein gene mutation in the United Kingdom does not affect the sensitivity and specificity of nucleic acid reagents, Shanghai recently discovered the new variant is China's native nucleic acid reagent detection.
    Questions: Are China's existing measures to prevent and control the spread of the new coronavirus effective?
    Xu Wenbo: China in April 2020 basically blocked the spread of the local new coronavirus, for the later imported cases or contaminated cold chain items caused by more than 10 cases of new coronary pneumonia cluster outbreak, have taken effective measures to stop transmission. Regular screening of high-risk populations, early diagnosis, early treatment, early isolation of infected persons and close contacts, as well as wearing masks, washing hands and maintaining social distance, is an effective measure to stop the spread of the new coronavirus in China.
    Questions: What further measures should be taken in response to the emergence of a new coronavirus variant?
    Xu Wenbo: People need not panic, we must strictly implement China's existing prevention and control measures, strengthen personal awareness of protection, especially for imported cases of hospitals or designated isolation hotels for health care and practitioners protection.
