Adhere to "dynamic clearing" and not shake the nucleic acid of all employees without leaving Tianjin unless necessary
In-depth attention | Tianjin vs. Omicron
Chai Yaxin Guan Xiaopu
Tianjin is fighting against the Omicron variant that is ravaging many countries around the world.
This is by far the largest number of local infections caused by Omicron in my country.
In the early morning of January 8, 2 cases of positive nucleic acid tests of the new coronavirus were found among the people who were willing to check and those who actively sought treatment in the fever clinic in Tianjin, both of which belonged to the Omicron variant.
As of 21:00 that night, there were 18 more positive cases in Tianjin.
From 21:00 on January 8 to 21:00 on January 9, 20 new positive cases were added in Jinnan District, Tianjin, and they have been transferred to the city's designated hospital for further diagnosis and treatment.
Epidemiological investigations, screening and control of persons involved in the epidemic, and collection of environmental samples are in intense progress.
At the end of the year and the beginning of the year, the epidemic spread in many places in China, coupled with the attack of Omicron, the epidemic prevention and control situation was severe and complicated.
As the current general policy of my country's new crown pneumonia epidemic prevention and control work, "dynamic clearing" is not only a summary and refinement of previous experience, but also the best choice at this stage.
Found together, put out together, and strive to use an incubation period or so to control the spread of the epidemic - the pressure of "external defense import, internal defense rebound" is not reduced, and it is more necessary to quickly and accurately implement "dynamic clearing".
The current round of Tianjin epidemic spreads fast, is concealed, and has strong penetrating power. Community transmission may have continued for some time.
Tianjin is the first city in China to report the discovery of imported cases of Omicron. Whole genome sequencing and sequence analysis, reviewed by the Chinese Center for Disease Control and Prevention, confirmed the detection of the new coronavirus Omicron variant (B.1.1.529 evolutionary branch).
Since then, imported cases of Omicron have been found in Guangzhou, Changsha, Shenzhen and other places. Except for Guangzhou, no local infection has been caused.
The Omicoron strains infected by the first two confirmed cases in Tianjin this time cannot be confirmed to be the same transmission chain as the sequences of the Omicron variant strains of imported cases previously discovered in the city.
"At present, from the current investigation and investigation, it has not been found that the first two cases are related to imported cases." On January 8, Zhang Ying, deputy director of the Tianjin Center for Disease Control and Prevention, revealed at a press conference that one case was a child and had been in Studying in Tianjin area, another adult works in Jinnan District, and his home is in Nankai District. He has not been away from Tianjin for nearly 14 days, and has no history of living in medium and high-risk areas.
The current round of Tianjin epidemic has shown the characteristics of rapid transmission, strong concealment and strong penetrating power.
From the relationship between cases and the chain of transmission, the virus has been circulating for at least three generations.
"That is to say, although we discovered this epidemic in the early hours of this morning, it is possible that the spread in the community has continued for a period of time." Zhang Ying said that it is not excluded from the closed control area, control area and prevention area. There may be other positive infections.
"From the current point of view, the biggest feature of the Tianjin epidemic is that these positive infected people have neither recently left Tianjin nor come from other places, so there is obviously community transmission." Jiang Qingwu, a professor at the School of Public Health, Fudan University He told reporters that this means that the virus has spread for several generations, how many sources of infection there are, and how many people have been infected. There are still many unknowns, and the pressure of epidemic prevention and control is huge.
Since the outbreak of the global new crown pneumonia epidemic, Omicron is the fifth variant that has been listed by the WHO as the highest level of concern - "variant of concern".
It has many genetic mutation sites and spreads quickly, but the symptoms caused by it are relatively mild and difficult to detect.
"The virus is constantly mutating, but it can be noticed that the proportion of mild patients and asymptomatic infections is increasing. This brings difficulties to epidemic prevention and control, because if it is a severe patient, it is easy to be detected, while mild and asymptomatic patients are more likely to be infected. The symptoms are relatively hidden and easy to be ignored. But as sources of infection, all three can spread the virus." Jiang Qingwu said.
At present, the infected people mainly involve the care institutions where the cases are located, school students and parents.
"Omicron is easy to infect children." Virology expert Chang Rongshan pointed out that Omicron's human adaptability is not only manifested in faster transmission and lighter symptoms, "about 30% faster than the delta variant, The rate of seeking medical treatment is less than one-third.” In addition, there is a trend of younger age.
Where the Tianjin epidemic came from is still uncertain.
In this regard, Jiang Qingwu believes, "The new crown virus always has a certain transmission path. On the one hand, it depends on whether it is caused by overseas imports. On the other hand, the recent outbreak of epidemics in many places in China depends on whether the virus is brought in by the flow of people. Both are possible, and supervision should be strengthened to check and fill gaps.”
Tianjin strictly implements control measures, does not leave Tianjin unless necessary, conducts nucleic acid screening for all employees, and follows up the guarantee work synchronously, and strives to fight with high efficiency and refinement
Some experts believe that Omicron is not a "big flu". A country and region needs a strong immune barrier and medical resources to defend against the threat of Omicron.
The complexity and difficulty of prevention and control of the current round of the epidemic in Tianjin cannot be underestimated. Only by strengthening the efficiency and refinement of related work such as flow adjustment, traceability, medical care, and security can we win the initiative.
On the evening of January 8, the Tianjin Epidemic Prevention and Control Headquarters issued the 2022 Circular No. 1, strictly controlling and not leaving Tianjin unless necessary.
Starting from 7:00 on January 9, Tianjin has started nucleic acid testing for all employees. All residents of Jinnan District, Nankai District, Dongli District, and Xiqing District will complete the nucleic acid testing of personnel in the area within 24 hours.
From 7:00 on January 10, all residents of the other 12 districts will complete the nucleic acid testing of personnel in the area within 24 hours.
"Nucleic acid testing of all staff is the fastest way to detect cases at present. It can detect infected people in time, isolate people and prevent the further spread of the epidemic." Relevant personnel may be the outbreak point of the spread of the epidemic, and the virus will have an incubation period of 4 to 5 days, and there is a possibility that positive cases will continue to increase in the future. The epidemic can be brought under control in time.”
At present, Tianjin has suspended offline training services and custody services for off-campus education and training institutions, vocational training institutions, adult training institutions, and custody service institutions.
On January 9, all the teacher qualification exam interviews scheduled to be held in Tianjin were cancelled, some subway stations were temporarily closed, and many scenic spots were temporarily closed.
At the same time, relevant safeguard work is also being followed up.
Tianjin has launched a joint emergency response mechanism to ensure the supply of people's lives. The stock of vegetables in wholesale markets and supermarkets has been increased from 2 days to 3 to 4 days, and the stock of rice, noodles and oil has been increased from 20 days to 30 days.
Tianjin's daily necessities market is currently in sufficient supply and prices are stable.
Some immunologists said that there is still a lot of uncertainty in the Tianjin epidemic.
Since a large number of commuters travel between Tianjin and Beijing every day, if it is not well controlled, it may directly affect Beijing.
In fact, Tianjin also quickly and clearly requested that it take quick and decisive measures to block the transmission channels of the epidemic and resolutely build a "moat" for epidemic prevention and control in the capital.
On the afternoon of January 9, the Beijing Center for Disease Control and Prevention issued a document reminding that Beijing's epidemic prevention and control faces dual risks both at home and abroad.
The Spring Festival is approaching, the flow of people will be more frequent, and the Beijing Winter Olympics and the Winter Paralympics will be held soon. The epidemic prevention and control cannot be relaxed for a moment. ” principle, strictly implement the responsibilities of the Quartet, be strict, scientific and precise, and effectively control and reduce the risk of the spread of the epidemic.
Tianjin personnel entering (returning) Beijing are required to strictly implement prevention and control measures, personnel from the city should not go to Tianjin unless it is necessary, and personnel from Tianjin should not come to Beijing unless necessary, and commuters from Beijing and Tianjin are advised to work from home.
"Beijing has always done a good job in epidemic prevention and control. In the near future, it can focus on fever clinics, quarantine points for entry personnel, etc., and take strict precautions to prevent problems before they occur." Jiang Qingwu suggested.
The cumulative number of confirmed cases in the world exceeds 300 million, and internal and external defenses are facing challenges. Adhere to "dynamic clearing"
Omicron has ravaged the world and has become a major epidemic strain in the United States, India and other countries.
On January 4, the number of newly confirmed cases in the United States set a record of 1.02 million new cases in a single day, and it has remained high since then.
According to the Associated Press, the "culprit" behind the explosive increase in the number of infections is Omicron, which has replaced Delta as the main epidemic strain in the United States.
The World Health Organization has warned that the rising number of infections around the world could increase the risk of new, more dangerous mutant strains.
"Although from an individual perspective, Omicron appears to have a lower risk of hospital admission than Delta, Omicron may pose a greater threat due to the sheer number of infections." Kathryn Smallwood said.
Up to now, the cumulative number of confirmed cases of new coronary pneumonia in the world has exceeded 300 million, with an average of nearly 1.9 million new confirmed cases per day in the past week, more than twice the peak of the previous wave of epidemics.
What is certain is that the global epidemic is still in a pandemic state. Due to factors such as the relaxation of control in many countries and the easy occurrence of infectious diseases in winter and spring, China's foreign defense import pressure has further increased.
According to the National Health and Medical Commission, on January 8, there were 92 new local cases in the country, distributed in Henan, Shaanxi, Tianjin, Zhejiang and Guangdong.
Among them, with the joint efforts of all parties, the epidemic situation in Xi'an, Shaanxi has shown a dynamic downward trend recently, the risk area is decreasing, and the community cases tend to be "dynamically cleared", and the prevention and control work has achieved results.
Whether it is the Omicron variant discovered in Tianjin or the delta strain that caused the epidemic in Xi'an, the rapid spread, relatively insidious onset and strong infectivity are the common problems brought about by both.
In response to the cunning and ever-changing virus, the epidemic should be controlled at a higher level, at a lower cost, and in a shorter time, reducing the impact on economic and social development and people's production and life, and ensuring the sustainable, healthy and stable development of the economy and society with good prevention and control results. It is the constant consideration behind China's epidemic prevention strategy.
Since August last year, my country's epidemic prevention and control has shifted to the "dynamic clearing" stage of precise prevention and control of the entire chain.
Before the epidemic does not spread, or before the infected person does not have the ability to spread, find the close contacts and sub-close contacts, control the possible infected people in advance, and strive to use an incubation period or so to control the spread of the epidemic.
Against Omikron, we must persist in "dynamic clearing".
"Dynamic reset" is China's "magic weapon" to control the epidemic.
"'Dynamic clearing' is the most correct decision in terms of both practical and social effects. In dealing with Omicron, we must also adhere to this policy and remain unswerving." Jiang Qingwu said.
People first and life first are the starting point and end point of all prevention and control measures. Quickly and accurately implement "dynamic clearing" to achieve maximum results with minimum cost.
"Dynamic clearing" is not "zero infection", but in the stage of normalized prevention and control, it is necessary to maximize early detection, early diagnosis, early isolation, and early treatment, and resolutely prevent the continuous spread of the epidemic in the community.
When there are no local cases, maintain a high degree of vigilance; when there are local cases, timely detection, rapid disposal, precise control, and effective treatment.
"We are not yet capable of not having a single local case, but we have the ability and confidence to quickly put an end to the epidemic when a local case is discovered. We are not pursuing 'zero infection', but seeking to eliminate the epidemic as soon as possible." Liang Wannian, head of the expert group of the National Health Commission's Leading Group for Epidemic Response and Disposal, said.
So, what is the specific path to achieve "dynamic clearing"?
The virus is constantly mutating and the risk of imported epidemics is increasing. How can we achieve an incubation period to control the epidemic?
In this regard, Liang Wannian summed up the "five precisions": first, to accurately identify the source of infection, mainly through nucleic acid detection and screening; second, to accurately identify close contacts, mainly through epidemiological investigation and big data technology; third, accurate planning The determined epidemic areas, epidemic spots, and scope of control are mainly through comprehensive research and judgment; the fourth is to take precise prevention and control measures to be effective, implementable, warm and sustainable; the fifth is to accurately balance the relationship between epidemic prevention and control and normal production and life .
"Dynamic reset" is a systematic project, and it pursues speed and accuracy. If there is no speed and accuracy, it will be difficult to achieve "dynamic reset".
On January 9, netizens discovered that a number of Tianjin municipal government Weibo accounts, including @金云, were regularly broadcasting the city's fever clinic and nucleic acid test waiting information, "every 2 hours from 6 o'clock."
The meticulous and methodical work has received many compliments.
Some Tianjin citizens mentioned that since the outbreak of the epidemic in 2020, Tianjin has always been like this and has never stopped.
In addition, Weibo accounts such as @ tonight news, @ tianjin daily, @ tianjin release also regularly broadcast relevant information.
"Since the outbreak of the epidemic, our ability to handle the epidemic has made great progress. However, it is undeniable that there will still be some gaps in different regions in terms of scientific and precise epidemic prevention and control." Jiang Qingwu said that local government departments have deployed epidemic prevention and control When taking various measures, it is necessary to take into account both the aspects and the points of care; it is necessary to effectively manage and control the risk of the epidemic, and at the same time, it is necessary to free up the hand to grasp economic development and protect people's livelihood.
This tests the level and ability of governance in various places.
In the third winter of fighting against the epidemic, is my country's epidemic prevention system enough to deal with mutants like Omicron?
"I am very confident that our country's epidemic prevention system can deal with mutants like Omicron." Liang Wannian said that confidence comes from many aspects, one of which is the high vaccination rate.
Actively and proactively vaccinate against the new crown virus, while protecting yourself, but also do your part to effectively control the spread of the new crown virus.
Up to now, more than 2.8 billion doses of the new crown vaccine have been vaccinated nationwide, and more than 1.2 billion people have completed the whole process of vaccination.
In the face of the epidemic, different countries have adopted different strategies.
For China, putting people first and life first is the starting point and end point of all prevention and control measures.
At this stage, we still insist on "dynamic clearing", which is to achieve maximum results at the least cost, and effectively protect the lives and health of the people and economic and social development.
Jiang Qingwu believes that the CPC Central Committee puts people's life and health first, which is an important starting point for implementing the "dynamic clearing" policy.
The advantages of the system determine that we have strong mobilization and organizational capabilities. All walks of life work together to prevent and control the epidemic. This is the supporting force for "dynamic zero" to be implemented and effective. It is also difficult for many countries to achieve and imitate. of.
