After B-ultrasound, there are these clues (what is B-ultrasound)

The world we live in now is still different from the epidemic-free period.

Late at night-65438+February 26th, the National Health Planning Commission announced that there were two main points:

1. novel coronavirus was renamed novel coronavirus infection;

2. "Class B tube".

The upcoming data map of COVID-19 infected with "type B B tube"

In Haisir's view, this is, of course, the biggest adjustment of the anti-epidemic policy since Wuhan discovered novel coronavirus at the end of 20 19 and China launched an all-out war to stop the epidemic.

In essence, the virus is mutating, and the methods to fight the epidemic are also changing. There is a reason why there is no constant situation in the army. Water is changeable, changeable and naturally changeable.

Read the announcement of the National Health Commission carefully. Although it was released late at night, it doesn't mean that the "B and B subway" will be implemented at dawn the next day. The specific adjustment date was approved by the State Council and implemented on June 8, 2023.

So, does this mean that from now until next year, 65438+1October 8, we will still implement "Class B A management" as after the beginning of 2020? In Haisir's view, to some extent, it is true.

However, it must be noted that even in the past three years, the policy has been constantly adjusted and optimized. For example, there was no universal nucleic acid when it was initially blocked. It was not until this spring that Omicron flowed into the mainland and caused widespread spread in the local area. The nucleic acid of the whole people, and even almost all the people issued antigens during the Shanghai blockade, became a "tactic".

After that, the national antigen problem was terminated first. With the continuous introduction of the "Twenty Articles" optimization measures and the "New Ten Articles" optimization measures, the national nucleic acid has also come to an end.

65438+February 10, lanzhou railway administration Group Co., Ltd. resumed multiple trains.

Why do you want to do these optimizations? To a great extent, the whole country has unified understanding, and the probability of Omicron pneumonia is much lower than that of the original strain and Delta. This understanding is supported by the data after the outbreak in some overseas places and the investigation and analysis of the Shanghai spring epidemic in 2022 by the Zhang Wenhong team. In fact, it is also derived from the analysis of experts in various fields, and B-ultrasound tubes can be used. Finally, the decision-makers are determined to make policy adjustments.

Why not change the policy earlier? Why not adjust the policy when the weather gets warmer in spring, but in winter when the flu is generally high? This is what some friends talked about last night and this morning. In Haisir's view, as long as we look at some situations after the launch of "Article 20" and "New 10" and make a careful analysis, we can get some answers.

This is purely a personal problem—

First of all, China is a big country. Not only is it vast, but it also has a large population. There is also a unique feature in the world, that is, the population is concentrated, and there are many big cities with more than10 million people. The United States is also a country with a vast territory and balanced population distribution; India's land area is not as big as China's, but its population distribution is quite balanced on the whole. Even so, don't forget that the American epidemic started in a megacity like new york. The epidemic distribution in India is also similar. So, if China lets go of his decision, what will happen if there is any deviation? From "poison" to "20" and then to "new 10", it is actually a small step. Even if there are mistakes, there is a chance to adjust quickly. For example, after the implementation of the "Ten Articles of New China", some places lacked antipyretics. It is hard to imagine what will happen if all kinds of adjustments are made overnight and the new policy is fully implemented. Then, on June 8, 65438, the implementation of "Class B and B Management" was announced, which gave all localities more than ten days to prepare.

Secondly, although China has a vast territory and a large population, it is indeed a "national chess game", but it can be specific to grass-roots units around the country, and the specific methods of completing the work are different. In addition to the differences in climate and population density caused by the large land area, there are also differences in urban and rural areas, economic development level and people's understanding of the epidemic. It is appropriate to spend about ten days preparing specific analysis and deployment.

Third, in the spring and summer of this year, the data of Omicron's pneumonia rate did not have a complete answer. At that time, Singapore implemented a policy similar to that of China today; After that, China and Hongkong also made some adjustments. In fact, what is certain is that the data obtained from these adjustments have also made some reference for China's decision-making.

Haisir has repeatedly said that he believes that the world will come as usual. Now with "B-level management", we are getting closer and closer to the world as usual. In the past two days, there have been rumors on the Internet, such as the reappearance of "original species". It was later confirmed as a rumor by experts.

In fact, from the perspective of natural evolution, the virus should not have "atavism". However, it should be noted that the fact that novel coronavirus was renamed as novel coronavirus infection does not mean that there is no possibility of pneumonia after infection. In fact, a common viral cold may develop into pneumonia or even severe pneumonia. Some data show that the incidence of pneumonia after Omicron infection is still about 16%. Especially for people over 60 years old, the probability of pneumonia is much greater than that of young people.

Class b tube, but it doesn't mean to let go!

Don't forget that everyone is the first responsible person for his own health.

A few days ago, Li Qun, director of the Emergency Center of China CDC, also said that after the infection in COVID-19 is adjusted to Class B infectious disease, the frequency of epidemic announcement will be adjusted to once a month according to the change of epidemic situation.

Open outbound tourism should also pay attention to the word "orderly". For example, "airlines should do a good job of epidemic prevention on board, and passengers should wear masks when flying" actually proves that the world we are in now is still different from the epidemic-free period. The more we pay attention to this aspect of self-discipline, the sooner the world will come!
