On December 28, at a press conference held by the National Health Commission, Peng Zhibin, director of the Respiratory Infectious Diseases Division of the Infectious Disease Management Department of the Chinese Center for Disease Control and Prevention, saidRecently, jnThe 1 variant is rising rapidly worldwide and has become the dominant circulating strainIn some countries, the epidemic has risen more sharply. CurrentThe situation of the new crown in our country is at a low level of epidemicjn.The proportion of 1 variants is also relatively low, but it is also on the riseIt is possible to gradually develop into a domestic epidemic strain
At the regular policy briefing held this afternoon, Li Zhengmao, director of the Department of Planning, Finance and Regulations of the National Bureau of Disease Control and Prevention, said that monitoring shows that among the local epidemic strains of the new crown epidemic in China, jnThe proportion of variants 1 is relatively low, but it is also on the rise. A total of 490 JN. were reported nationwide1 Variant Sequence,Among them, 443 cases were imported, accounting for 90%.There are 47 local cases. The available evidence suggests that jn1. The immune evasion and transmissibility of the variant were enhanced, but its pathogenicity was not enhanced, and specific antiviral drugs were still effective.
Previously reported:Infection JnWill the symptoms be more severe after the 1 variant?
jn.The 1 variant belongs to the Omicron variant, and from the recent assessment of the World Health Organization based on the available evidence, JN1 The transmissibility and immune evasion of the variant are enhanced, but there is no evidence that it is more pathogenic. Moreover, there is a cross-effect between previous infection and XBB vaccination, which is expected to pose a low public health risk.
Peng Zhibin saidThe New Year's Day and Spring Festival holidays are approaching, the Spring Festival is about to begin, and the flow of people will rise sharply, and it is expected that the new crown epidemic in China may rebound to a certain extent。During the Spring Festival travel period, the epidemic of the new crown epidemic and other respiratory infectious diseases may rise, especially increasing the risk of severe illness and death of vulnerable people such as the elderly and patients with chronic underlying diseases, which may bring certain pressure to the medical service system in rural areas with relatively weak treatment capacity. Therefore, it is necessary to attach great importance to it, make careful arrangements, and make preparations in all aspects in advance.
In the next step, the China Center for Disease Control and Prevention will continue to pay attention to the changes in the epidemic situation and epidemic strains abroad, and conduct timely monitoring, early warning and risk assessment.
