(Fighting against New Coronary Pneumonia) Four questions about the current Shanghai epidemic: What is the best choice for fighting the epidemic?
China News Agency, Shanghai, April 10 Question: Four questions about the current Shanghai epidemic: What is the best choice for fighting the epidemic?
China News Agency reporter Li Chun
According to Chinese official data, Shanghai added 1,006 local confirmed cases and 23,937 local asymptomatic infections on April 9.
At present, the whole area of Shanghai is in a static state, and the epidemic prevention and control situation is still severe and complicated.
Liang Wannian, head of the expert group of the National Health Commission of China's New Coronary Pneumonia Epidemic Response Leading Group, Executive Vice Dean and Professor of the Vanke School of Public Health and Health of Tsinghua University, pointed out in an interview with the media in Shanghai on the 10th that Shanghai's epidemic prevention and control is in the process of At the critical moment, if you don't advance, you will retreat.
"Dynamic clearing" is currently the best choice for Shanghai to fight the epidemic.
What is the current situation of the epidemic in Shanghai?
How to judge the epidemic situation in Shanghai?
Liang Wannian pointed out that Shanghai is currently at the peak of the epidemic, the number of reported cases is still high, there has been widespread community transmission, and outbreaks have occurred in some areas, and the overall prevention and control situation is extremely severe and complicated.
"But according to the epidemic parameters of the variant strain of Omicron, we have not seen an exponential rise in the daily epidemic in Shanghai." Liang Wannian said: "This shows that the prevention and control strategy adopted. And the measures are playing an important role in containing the momentum of the exponential rise, which is very important, so let's not panic."
Liang Wannian said that Shanghai is still at the critical moment of implementing "dynamic clearing", and the epidemic prevention and control is actually in a stalemate.
"We must seize this time window tightly to make efforts and form a joint force."
What are the difficulties in preventing and controlling the epidemic in Shanghai?
Talking about the characteristics of the Shanghai epidemic, Liang Wannian said that the main epidemic strain of this epidemic is Omicron BA.2, which spreads very quickly and is very concealed, resulting in a very large proportion of asymptomatic infections and mild cases. high, increasing the difficulty of prevention and control.
The early transmission chain is still relatively clear, but community transmission has gradually emerged in Shanghai. At present, most communities have cases, which is already widespread community transmission, and more decisive and firm measures must be taken.
In addition, the epidemic prevention and control work has put forward very high requirements on the organizational capacity, management capacity and corresponding prevention and control capacity of the city.
A city of 25 million people needs to work together to complete a certain action within a certain period of time, which is a very big challenge for all parties.
Liang Wannian also said that Shanghai is currently facing the pressure of three lines of defense: preventing the spread of the city, preventing overflow, and preventing foreign imports. The most important thing at present is to prevent internal proliferation and rebound.
How to make the prevention and control work faster, more accurate, and more effective, and how to better balance the epidemic prevention and control with social and economic development, and the normal life of the people, is also an important proposition for Shanghai, a mega-city.
When will the "inflection point" of the epidemic appear?
At present, the whole region is static in Shanghai, and the number of new local infections is still increasing every day.
When will the "inflection point" of the epidemic come?
When will Shanghai be able to "move up"?
Relevant issues have attracted the attention of all parties.
Liang Wannian said that according to internationally recognized data, if there is no intervention, a person infected with the Omicron variant will infect 9.5 people.
The comprehensive prevention and control measures currently taken, including nucleic acid testing, global static management, etc., are to do everything possible to reduce the transmission value to below 1.
"Once the pressure falls below 1, it means that one person cannot infect one person, and the 'inflection point' of the (epidemic) appears, and there will be no sustained transmission." He said.
As for when the social dimension in Shanghai will be "cleared", the expert also said that to determine whether the social dimension is cleared, in addition to the data of newly infected people reported every day, it also depends on whether the continuity of the spread of the epidemic has been cut off. This is an important indicator.
"If one day all our new cases are among the close contacts, or these key groups in our field of vision, are found through active screening, I think, at this time, we have reached the social level' The goal of dynamic clearing." Liang Wannian said.
What is the best choice for Shanghai to fight the epidemic?
He has been fighting Omicron for some time. In Liang Wannian's opinion, this mutant strain "comes too fast", and he "can't get past it" with the past methods of dealing with mutant strains such as Alpha, Beta, and Delta.
At present, Shanghai is experiencing a race between epidemic prevention and control and the mutant strain of Omicron. It is necessary to control the epidemic at a faster speed, so as to find out quickly, deal with it quickly, and control it quickly.
Accurate and fast, this is one of the cores of "dynamic clearing".
"We must adhere to 'dynamic clearing', which is also the best choice for Shanghai to fight the epidemic." Liang Wannian said.
He said that Shanghai has a large proportion of the elderly population, and the absolute number of key groups such as patients with underlying diseases is very large. Once infection occurs, the number of infected people will be a huge number.
Not to mention that in the context of the widespread epidemic, if the virus mutates, it will cause greater harm to people's lives and health.
Liang Wannian emphasized that "lying flat" is not China's choice.
Under the anti-epidemic concept of "people first, life first", China still has time windows and opportunities, and has the ability, foundation, and "toolkit" to insist on "dynamic clearing".
This general policy of China's epidemic prevention and control has been relatively mature and effective in the specific implementation process.
