China News Service, March 24th. In the early morning of the 24th, Zhang Wenhong, director of the Department of Infectious Diseases at Huashan Hospital Affiliated to Fudan University in Shanghai, posted a long article on his personal Weibo, responding to recent netizens' concerns and questions about the epidemic.
Zhang Wenhong said that the new crown is not so scary, but the battle is difficult to fight.
In this battle in Shanghai, we don’t do one size fits all. We hope that we can minimize the impact on our lives while minimizing the omission of screening. It is definitely not easy, and it will inevitably fail, but it also shows that we will never go back in the fight against the epidemic. determination.
The following is the full text of Zhang Wenhong's release:
The new crown is not so scary, but the battle is difficult to fight
Reality is skinny.
In the past few days, Shanghai is fighting the most difficult battle since the fight against the epidemic. The number of infected people has exceeded expectations a year ago, and medical resources have suddenly become strained.
The backup hospital in Shanghai has also been activated. In addition to participating in the ward rounds of designated hospitals in Shanghai, I am also concerned about the work of several of our centralized admission and isolation points.
Not long after the isolation point was set up, the medical and logistical teams were working together. Although most of the people who entered the isolation point were asymptomatic and mildly infected people, these people still had the risk of disease progression, and they were suddenly diagnosed with the new crown. All need comfort.
Now, the colleagues of our team have sorted out the hustle and bustle, and treated a large number of infected people with asymptomatic and mild symptoms in a short period of time. We cannot pretend that there is no difficulty, but we are constantly learning as the epidemic changes. And improve, strive to make patients feel better and recover faster.
Just now, in the early morning, everyone was still busy with the work of the isolation point. Before writing this Weibo, I had just finished discussing the stockpiling of new specific antiviral drugs with President Ma Xin, the person in charge of the Baoshan Treatment and Isolation Center. I had a little spare time. Hurry up and report what happened recently and answer some of your concerns.
1. What model should be adopted to fight the epidemic in the future
Many people are concerned about the epidemic in Shanghai, and there are also many criticisms and suggestions on Shanghai's prevention and control strategies.
Shanghai is a super-large international city. Faced with the attack of the Omicron virus strain, which is dominated by asymptomatic infection, it was initially found that the number of cases increased exponentially after infection, making it very difficult to prevent and control.
How to keep the city from shutting down, maintain basic economic activities, and finally achieve epidemic control, is indeed facing great difficulties.
When the epidemic spreads, if you want to prevent the city from shutting down, you need to make constant strategic adjustments under the support of data.
The current strategies are: rolling screening, focusing on key points, and cutting off the chain of transmission.
The big data of screening tells us that a positive sign has quietly emerged: the proportion of rolling screening cases in non-controlled areas is gradually decreasing, accounting for only 10% of the total cases, indicating that the social epidemic is gradually under control.
Although the inflection point of the epidemic has not yet appeared, the conditions for forming an inflection point have gradually been met.
2. The National Health Commission issued an update to the nucleic acid testing guidelines, revealing new trends in my country's future anti-epidemic
On March 22, the National Health and Medical Commission issued a notice on the issuance of the "Regional Novel Coronavirus Nucleic Acid Detection Organization Implementation Guidelines (Third Edition)".
The first is to emphasize scientific precision and carry out nucleic acid detection in delineated areas.
The second is to change the "full staff" in the second edition of the "Guide" to "area", and the size of the area is determined by the needs of epidemic prevention and control.
This indicates that the future anti-epidemic has gradually entered a new stage, and the anti-epidemic model of shutting down economic life in the whole region and conducting multiple rounds of testing for all staff will be gradually updated.
But the question is, can we outrun Omikron without a global shutdown and full-staff testing?
The new guidelines of the National Health and Medical Commission say this: "Further clarify the completion time limit" for nucleic acid testing.
All provinces and cities (including megacities with a permanent population of more than 10 million in urban areas) do not distinguish between population sizes, and match the sampling and testing forces according to the target of completing the city's nucleic acid testing within 24 hours.
This requirement is very high, but it is the basic requirement to ensure that subsequent rolling screening can escape the spread of the virus.
Omicron's speed, in a sense, if it is not fast, we have no chance to outperform Omicron.
On the day of the release of the new guidelines, Shanghai put "strict nucleic acid screening, speeding up the improvement of large-scale nucleic acid detection capabilities, and strengthening the coordination and precise scheduling of the whole process of 'collection, delivery, inspection, and reporting'" as the focus of work. Omicron's abilities.
3. Effectiveness data of Hong Kong’s blockbuster vaccines announced, and the third vaccination provides comprehensive protection
I recently discussed the Hong Kong epidemic control process with Hong Kong experts many times, especially the high mortality rate of the elderly.
Today, the School of Public Health of the University of Hong Kong pre-published a paper on the role of vaccines online. The results are very important. A total of 12.7 million doses of vaccines have been vaccinated in Hong Kong's 7.3 million population. Both vaccines can prevent serious illness and death. Among adults, the protection rate of two doses of inactivated coronavirus against severe COVID-19 and death was 74.1%, which was inferior to that of BNT162b2 (88.2% effective rate).
The good news is that the three-dose vaccination of the two vaccines can provide a very high level of protection against severe illness and death, and the protection rate has reached more than 95%.
This data has laid the foundation for China to get out of the epidemic in the future.
4. In the future, fighting against the epidemic and maintaining the normalization of life should be placed in a position as important as dynamic clearing
This time the outbreak of the epidemic in Shanghai, all parties in the society have devoted themselves to the comprehensive anti-epidemic work.
There have also been reports from the masses that "the care of life in the closed area is not enough, the closure time is too long, and the repeated closure and control of the hospital makes it difficult to see a doctor".
These problems all exist and should not be avoided. In the future fight against the epidemic, we must solve them one by one, otherwise, the significance of the successful fight against the epidemic will be greatly reduced.
It is now clear that the relevant parties have seen these problems and are facing them head-on.
The fight against the new crown epidemic will be a long-term process. We cannot hold the mentality of killing the virus if we can’t do it. We must not only control the epidemic, but also protect the lives of residents, keep the medical treatment channels unblocked, and also protect the health of private small and micro enterprises. Survive.
These will be the focus of the next phase of Shanghai's fight against the epidemic.
The fight against the virus is not over yet, but life goes on.
The battle in Shanghai is still in a stalemate, but at least today, we have seen that new drugs have been launched, the three-injection vaccine has been strengthened and effective, and the rapid and accurate nucleic acid screening is expected to beat the virus.
In this battle in Shanghai, we don’t do one size fits all. We hope that we can minimize the impact on our lives while minimizing the omission of screening. It is definitely not easy, and it will inevitably fail, but it also shows that we will never go back in the fight against the epidemic. determination.
During this period when everyone felt that it was not easy, the technical support to get out of the epidemic was quietly and gradually available.
