The National Centers for Disease Control and Prevention issued the relevant Q & A on Friday (December 15) about the coronary virus JN.1 mutant strain, saying that since the first discovery of local JN.1 mutations in November, as of December 10, December 10thOn the day, the Communist Party of China monitored seven JN.1 mutant plants in the Chinese local case.Affected by international popular plants and input cases, it is not possible to rule out the possibility of JN.1 mutant strains become domestic advantageous popular strains.
According to the China CCTV News client, the National CDC introduced that since November this year, the proportion of JN.1 mutant plants has increased rapidly in global popular poison strains.%Increase to about 30%in early December.As of December 10, at least 40 countries and regions around the world have monitored the JN.1 mutant strains.From the perspective of distribution, Europe has the highest proportion, and the proportion of JN.1 mutant plants in the Americas and other continents also show a rapid growth trend.
The National CDC said that the main popular strains in China are still EG.5 and its sub -branches.Since the first discovery of local JN.1 variants in November, as of December 10, the Communist Party of China has monitored seven cases of JN.1 mutant strains in the Chinese local case.Although the current level of JN.1 variants is extremely low in China, it is influenced by international popular plants and input cases in the future. It does not rule out that JN.1 mutant strains become the possibility of Chinese domestic advantageous plants.
The National CDC also introduced that from the perspective of the popular situation of various countries, recent JN.1 mutant plants have grown rapidly in many countries, but research shows that in terms of communicationNot obvious.The World Health Organization report shows that the new coronal virus vaccine containing XBB.1.5 is still effective for JN.1 mutant plants.Therefore, under the premise of widely immunization (including vaccination and natural infection) for the population of the crowd to Omircong's mutant plants, the spread of JN.1 mutant plants may be relatively limited.
According to reports, JN.1 is the second -generation subcate branch of the Coronal Virus Omikon BA.2.86, and it is also a sub -branch with a strong dissemination advantage in the BA.2.86 mutant strain.The World Health Organization's evaluation includes BA.2.86, including JN.1, the risk of clinical severe infection is low.Chinese monitoring data shows that those infected with JN.1 variants are mild or asymptomatic.Symptoms caused by different mutant plants are often similar, and the type and severity of the symptoms usually depend more on individual immunity.Based on existing evidence, the public health risks of JN.1 mutant strains are relatively low.
