The New Year’s Day and the Spring Festival are approaching the risk of spreading the epidemic!Kexing isolates Omi Kiron strain

by admin

On December 11, the Joint Prevention and Control Mechanism of the State Council held a press conference on the recent COVID-19 prevention and control and vaccination work.

The spokesperson of the National Health Commission Mi Feng said that the current global pandemic of the new crown pneumonia epidemic is still in the development stage. The number of new confirmed cases per week continues to exceed 4 million, and the mortality rate is rising. The Omi Keron variant has further increased the uncertainty of the epidemic. , my country’s “foreign defense import” pressure continues to increase.

Mi Feng said that since December, my country’s new round of newly confirmed cases of the epidemic has mainly concentrated in port cities and adjacent areas. The key to epidemic prevention and control is “prevention.”

Mi Feng introduced that as of December 10, a total of 2.59 billion doses of new crown virus vaccines had been reported nationwide, and more than 1.16 billion people had completed the entire vaccination process.

On December 11, Zhong Nanshan, an academician of the Chinese Academy of Engineering, stated at the Life Science Sub-forum of the Greater Bay Area Science Forum that China‘s vaccination should achieve theoretical herd immunity, and the vaccination rate should reach 83% of the entire population. At present, 1.15 billion people in my country have completed the entire vaccination process, accounting for 81.9%. By the end of this year, they are confident to complete the target vaccination rate, laying a good foundation for herd immunity. He pointed out that most of the current vaccines, almost half a year after they are on the market, the immune antibodies have fallen and need to be bolstered. The domestically-made vaccine booster is real and effective, and the prevention of diseases has increased from 50% to 80%. He said that he is strengthening research on how to improve the efficiency of vaccination.

In addition, Kexing stated that the company obtained nasopharyngeal swab specimens from patients infected with the Omi Keron mutant strain of the new crown virus on December 5, and cooperated with the team of Professor Qin Chuan from the Institute of Medical Laboratory Animals of the Chinese Academy of Medical Sciences to carry out virus isolation and complete testing. Gene sequencing work has successfully isolated Omi Keron mutant strains and obtained sequencing results.

At the same time, Kexing and the Yuan Guoyong academician team of the University of Hong Kong have signed a cooperation agreement to introduce a sample of the Omi Keron mutant strain isolated from the University of Hong Kong, which arrived in Beijing on the afternoon of December 9 and transferred it to the P3 experiment of the Institute of Medical Laboratory Animals, Chinese Academy of Medical Sciences Room to carry out research. Kexing is also ready to develop new vaccines, and if necessary, it can quickly advance the development and large-scale production of new vaccines.

  New Year’s Day and Chinese New Year is approaching

  The risk of spreading the epidemic is greater

Wu Liangyou, deputy director of the CDC of the National Health Commission, said that at present, the global new crown pneumonia epidemic is still prevalent at a high level, the virus continues to mutate, and the risk of overseas epidemics being imported into my country continues to exist. If the “external defense” is guarded, there will be no internal rebound. New Year’s Day and Spring Festival are approaching, and the risk of epidemic spread is relatively high. We must work harder on scientific and precise epidemic prevention, and if we find an epidemic, we will completely extinguish it together to ensure that everyone spends a healthy and safe holiday.

  Shanghai, Zhejiang and Jiangsu are the same linked epidemic

Wu Liangyou said that the virus genome sequences of the epidemic cases in Shanghai, Zhejiang and Jiangsu are highly homologous, and they are the same related epidemic. At present, the epidemic situation in Shanghai is relatively stable, with no new cases for 3 consecutive days; the epidemic situation in Shaoxing, Ningbo, and Hangzhou in Zhejiang has developed rapidly, and the transmission relationship between cases is relatively clear, mainly involving families and crowds gathering places, related risk area control and risk The personnel investigation is in progress.

  Manzhouli epidemic spreads to 4 provinces and 6 cities

Wu Liangyou introduced that the sequencing analysis of the viral genome of the Manzhouli epidemic in Inner Mongolia showed that the epidemic was caused by a new overseas source and was not related to the previous epidemic in Inner Mongolia.

The outbreak first occurred in Manzhouli City, Hulunbuir, Inner Mongolia, and then related cases were found in two regional flags in Hulunbuir City, Tongliao City, Inner Mongolia, Qiqihar City, Heilongjiang, Harbin City, Shijiazhuang City, Hebei, and Haidian District, Beijing. 6 cities in provinces.

At present, the local epidemic situation in Manzhouli is still in a stage of continuous development. Recently, the number of reported cases has shown a fluctuating downward trend. The trend of the epidemic situation needs to be closely observed. The risk of the epidemic in Harbin, Heilongjiang has been reduced. There were only sporadic case reports recently, and no new cases were reported yesterday. There have been no new cases in Tongliao, Qiqihar, Shijiazhuang and Beijing for more than 5 consecutive days, and the epidemic has been well controlled.

  my country has the ability to detect imported cases of Omi Keron mutant strains in time

Wu Liang has introduced that, at present, whether the Omi Keron mutant has stronger transmission power and immune escape risk than the Delta mutant requires further observation. The Omi Keron variant does not affect the sensitivity and specificity of our country’s existing nucleic acid detection reagents. Our surveillance system has the ability to detect imported cases of the Omi Keron variant in a timely manner.

  Adverse reactions of children aged 3-11 years to receive the new crown vaccine are generally stable

Wang Huaqing, chief expert of the China Centers for Disease Control and Prevention’s immunization program, said that as of December 3, the adverse reactions reported by children aged 3-11 years old from the new crown vaccine were generally stable. More than 95% of adverse reactions reported by the age of 3-11 are general reactions. Most of the abnormal reactions are allergic rashes. The incidence of serious abnormal reactions reported in all age groups is below one in a million, and the incidence in the 3-11-year-old group is lower than that of adults and adolescents.

  “Dynamic clearing” is not “zero infection”

Liang Wannian, head of the expert group of the Leading Group of the National Health Commission’s Epidemic Response and Handling Work, said that dynamic zeroing is the current general policy for the prevention and control of the new crown pneumonia epidemic in my country. He said that “dynamic zeroing” is not “zero infection”. We currently do not have the ability to avoid a single local case, but we have the ability and confidence to quickly extinguish the epidemic when a local case is found. “Dynamic Zeroing” seeks to maximize the overall planning of social and economic development and epidemic prevention and control.

  The national overall nucleic acid testing capacity reached 29.95 million copies per day for single tube and single inspection

Guo Yanhong, Inspector of the Medical Administration of the National Health Commission, said that as of now, there are 11,744 medical and health institutions nationwide that can carry out nucleic acid testing. my country’s overall nucleic acid detection capacity has reached 29.95 million samples per day per tube. If it is paired with the “10-mix 1” detection method, the detection capacity can be doubled. At the same time, efforts are made to enable the “willing to do all inspections” group to get the results within 6 hours, and push relevant information to the masses in a timely manner through information technology.
