China News Service, February 23. Chang Zhaorui, a researcher at the Communication and Defense Department of the China Center for Disease Control and Prevention, said on the 23rd that my country has just experienced a pandemic, and the neutralizing antibodies remaining in the population will provide immune protection in the short term. It is believed that no secondary cases of XBB.1.5 have been found, and it is less likely to trigger a new round of large-scale epidemics in the near future.
On the 23rd, the Joint Prevention and Control Mechanism of the State Council held a press conference on consolidating major achievements in epidemic prevention and control.
At the meeting, a reporter questioned that the China Centers for Disease Control and Prevention recently released the national new coronavirus infection situation, and the report showed that one case of XBB.1.5 and one case of BQ.1 were newly added mutant strains.
What are the symptoms of XBB.1.5 infection?
Is it possible to trigger a new round of infection peaks?
Chang Zhaorui said that since the implementation of the "Class B and B Control" of new crown virus infection on January 8 this year, one case of local-related XBB.1.5 cases caused by imported cases has been discovered through monitoring, which is a core close contact person.
After detailed epidemiological investigation, health testing of relevant close contacts and expert judgment, no further cases were found.
According to the data from the US CDC website, from February 12th to 18th, XBB.1.5 accounted for the first (about 80.2%) of the epidemic strains in the United States. , such as Canada (37.8%), the United Kingdom (32.9%), and Germany (25.7%).
Although XBB.1.5 has a strong transmissibility, current data show that the symptoms of individuals infected with XBB.1.5 are similar to those of other Omicron strains, and no increase in its pathogenicity has been found.
Chang Zhaorui pointed out that at present, in the detection of new coronavirus mutant strains in my country, if the first reported (including imported and local) and international epidemic strains of focus are found, infection case investigations, core close investigations will be carried out, and risk research and judgment will be carried out. Once a new mutant strain with enhanced transmission, pathogenicity or virulence is found, take measures in a timely manner according to the relevant plan.
At the same time, my country has just experienced a pandemic, and the neutralizing antibodies remaining in the human body will provide immune protection in the short term. Expert research and analysis believe that it is less likely to trigger a new round of large-scale epidemics in the near future.
