Zhang Wenhong posted late at night: The new crown is not so scary, but the battle is difficult to fight

At 2:05 on March 24, Dr. Zhang Wenhong posted on Weibo late at night: The new crown is not so scary, but the battle is difficult to fight.

The reality is bone-chilling. In the past few days, Shanghai has been fighting the toughest battle since the fight against the epidemic, the number of infected people has exceeded the expectations of previous years ago, and medical resources have suddenly become tense. The reserve hospital in Shanghai has also been launched, and in addition to participating in the rounds of the designated hospital in Shanghai, I am also concerned about the work of several centralized treatment and isolation points. Although most of the people stationed in the isolation point are asymptomatic and mildly infected, these people still have the risk of disease progression, and they are suddenly diagnosed with new crown, and their inner trepidation and fright need to be soothed. Now, our team colleagues have sorted out the confusion, in a short period of time to treat a large number of infected people mainly asymptomatic and mild, we can not pretend that there is no difficulty, but we are constantly learning and improving with the changes in the epidemic, and strive to make patients feel better and recover health faster.

Just now, in the early morning, everyone is still busy with the work of the isolation point, before writing this Weibo, I just discussed with President Ma Xin, the person in charge of the Baoshan treatment isolation point, the reserve of specific antiviral new drugs, and there is a little idleness, and I hurry to report to you what has happened recently and answer some questions that everyone cares about.

1. What model should be adopted in the future fight against the epidemic

Many people are concerned about the epidemic situation in Shanghai, and there are many criticisms and suggestions for Shanghai's prevention and control strategies. Shanghai is a super large international city, this time in the face of asymptomatic infection-based Attack on the Aomi Kerong strain, the initial number of cases after infection has increased exponentially, and it is very difficult to prevent and control. How to keep cities moving, maintain basic economic activities, and finally achieve epidemic control is indeed facing great difficulties. When the epidemic spreads, if you want to keep the city from shutting down, you need to constantly make strategic adjustments with the support of data. The main strategies adopted at present are: rolling screening, locking the focus, and cutting off the chain of transmission. Screening big data tells us that a good sign has quietly emerged: the proportion of cases screened by all employees in non-controlled areas has gradually declined, accounting for only 10% of the total cases, indicating that the social epidemic situation 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 promulgated an update to the nucleic acid testing guidelines, revealing the new trends in the mainland's future fight against the epidemic

On March 22, the National Health Commission issued a notice on printing and distributing the Guidelines for the Implementation of Regional Novel Coronavirus Nucleic Acid Testing Organizations (Third Edition). The first is to emphasize scientific precision and carry out nucleic acid testing on the demarcated areas. The second is to modify the "full staff" in the second edition of the "Guidelines" to "region", 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 global economic life and conducting multiple rounds of full testing will be gradually updated. But the question is, without a global shutdown and full testing, can we run past Omikeron?

The new guidelines of the National Health Commission say this: "Further clarify the time limit for the completion of nucleic acid testing". 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 sampling and testing forces according to the goal of completing the city's nucleic acid testing within 24 hours. This is a high requirement, but it is the basic need to ensure that the follow-up rolling screening can run through the spread of the virus. The speed of Aumechjong, in a sense, if it were not for the speed of the fast, we would not have a chance to outperform the Aomi Keron. On the day of the release of the new guidelines, Shanghai took "strict nucleic acid screening, accelerated the improvement of large-scale nucleic acid detection capabilities, and strengthened the coordination and accurate scheduling of the whole process of 'collection, delivery, inspection and reporting'" as the focus of work, which began to have the ability to outperform Aomi Kerong.

3. Hong Kong's blockbuster vaccine effectiveness data was released, and the third dose of vaccination provided comprehensive protection

I have recently discussed the epidemic control process in Hong Kong with Hong Kong experts many times, especially on the issue of high case fatality rates among the elderly. Today, the School of Public Health of the University of Hong Kong pre-published a paper on the role of vaccines online, and the results are very heavy, Hong Kong's 7.3 million people have received a total of 12.7 million doses of the vaccine, both vaccines can prevent serious disease and death, and in adults aged ≥ 60 years old, the two-dose inactivated coronavirus vaccination has a protection rate of 74.1% against severe COVID-19 and death, which is not as good as BNT162b2 (88.2% effective). Fortunately, three doses of both vaccines provide a very high level of protection against severe illness and death, with protection rates of more than 95%. This data has laid the foundation for China to get out of the epidemic in the future.

4. In the future, the fight against the epidemic and the maintenance of normal life should be placed in the same important position as dynamic zeroing

The outbreak of the epidemic in Shanghai has involved all parties in society in the work of comprehensively fighting the epidemic. There have also been mass reactions, "the life in the sealing and control area is not enough to take care of, the sealing and control time is too long, and the hospital's repeated sealing and control causes normal medical treatment difficulties". These problems exist and should not be avoided, and we must solve them one by one in the future fight against the epidemic, otherwise, the significance of the success of the fight against the epidemic will be greatly reduced. It is now clear that the parties concerned have seen these problems and are confronting them head-on. The fight against the new crown will be a long-term process, we can't hold the mentality that we can't kill the virus, we must not only control the epidemic, but also protect the lives of residents, keep the medical channel open, and also ensure the survival of private small and micro enterprises. These will be the focus of the next phase of Shanghai's fight against the epidemic. The fight against the epidemic is not over, but life goes on.

The Shanghai campaign is still glued, but at least today, we have seen that new drugs have landed, the vaccine has been strengthened and effective, the rapid and accurate screening of nucleic acids is expected to run through the virus, and the whole country has begun to take precautions to prepare for the construction of backup isolation point hospitals. This battle in Shanghai, not to engage in one-size-fits-all, hoping to minimize the impact on life while trying to avoid leakage and screening, is certainly not easy, and it is inevitable that it will not go smoothly, but it also shows our determination to never take the road back from the fight against the epidemic. During this period when everyone felt that it was not easy, the technical support for getting out of the epidemic was quietly and gradually available.
