According to the CDC, scholars believe that Omicron is unlikely to be the last variant. What does this mean?

1. Liang Wannian, leader of the expert group of the National Health Commission epidemic response and disposal leading group: From the two dimensions of transmission speed and mortality, the severity of Omicron is much higher than that of influenza. Without protective measures, 1 person can spread 9.5 people on average; The death rate of Omicron is about 7 to 8 times that of influenza; The mortality rate of Omicron in the elderly over 80 years old is over 10%, which is nearly 100 times that of common influenza. COVID-19 is the birthplace of this sudden epidemic. So far, there is no definitive treatment to effectively control the spread and variation of this virus in the world. Therefore, it also means that this virus will coexist with human beings for a long time. As for what the future will be like, according to the success of the current research, no one can really give a definite answer.

Second, it means that the current global epidemic is still at a high level. We must adhere to the general principles of "external defense investment, internal defense rebound" and "dynamic zero clearing". To put it bluntly, it is to continue prevention and control and intervene through artificial isolation. This means that the mutation in COVID-19 will exist for a long time, and it also means that the epidemic prevention and control will also exist for a long time. It means that nucleic acid detection needs to be carried out for a long time, which means that the policy of "dynamic zero clearing" needs to be consistent. COVID-19, normalization, can't relax, rely on everyone. Three-character classics of epidemic prevention, always remember! We need to fight the virus to the end!

Third, it means that the external environment is severe. This also means the need to release power to achieve a harmonious society. It's like a festival in the Tang Dynasty, where shepherds were released in the Han Dynasty. The governor of the Qing dynasty. Doesn't anyone know that these people will use their positions to seek benefits for themselves? How is that possible? Power itself is accompanied by interests, as well as money (ancient land). Even if this power is temporary, it is actually very profitable. Don't you see who is doing those serious or informal service industries? Why can only they do it?

Fourth, it means that we should not be optimistic about the epidemic and should not be too lax. Some time ago, the epidemic was severe, and high-risk areas were increasing, so many people had to stay at home. During the period when it was just unsealed, people in the street were wearing masks, and their awareness of epidemic prevention was still relatively strong. However, the epidemic has been slightly stable recently, and the control is not as strict as before. It may also be that the weather is too hot and wearing a mask is a bit boring. I went shopping two days ago and found that many people don't wear masks very much. As a result, when people who don't wear masks pass by, I always habitually hold my breath for a while, fearing that there will be viruses in the air. I am so careful because I dare not take risks. If I win the lottery, it will be too late to regret it.

First discovered in Wuhan, the whole world thought it was the next SARS, and began to be cynical. Even something as disgusting as Yuan Yuan Diary appeared in our own country. Subsequently, cases began to appear in foreign countries, and western countries still hoped to control themselves, from the beginning of "no problem" to "miraculous disappearance", to the last "group immunity", and now "no detection means no cases". You can see that from beginning to end, except for China, the world's attitude towards the COVID-19 epidemic is like the diplomatic trilogy in Yes, the Prime Minister: "At first, we said nothing happened."

Therefore, from the beginning, the backward reaction and decision-making ability of the west could not cope with this highly contagious virus at all. If COVID-19 didn't have such a high mutation ability, it might really turn the West into group immunity. But? COVID-19 is not only changeable, but also highly changeable. And the mutation direction constantly strengthens the ability to break through the human immune barrier. In other words, group immunity is completely impossible to achieve and has become a joke. Anyone who has played plague company knows that with the increase of infected people, more DNA can be collected and DNA can adjust its evolutionary direction.

In fact, the spread of the virus is similar. If it spreads too much, there will always be variation. You said that Omicron is rampant in the west. How many directions of variation have you collected? Here, I make a bold assumption: COVID-19's new variety has appeared, but it is either undiscovered or not enough to replace Omicron's dominant position.

After a period of time, the varieties with absolute advantages will be cultivated, and perhaps the future will be the world of new varieties. The whole world is closed, so China is closed. After injecting foreign vaccines, infection in COVID-19 means catching a cold. Why not China? Strengthening needles are also needed to strengthen the needles. Yes, it's free, but it costs people money. If it is closed all day, can domestic beneficiaries lie down all day to make money? Just like the road in Guangzhou, it can never be repaired. It's just been repaired over there. It can be repaired here. So when can we get to China? China is a big exporter. Now that foreign productivity has recovered and China is still closing the city, what else can it export?

Coronavirus is an RNA virus that constantly mutates when it is unstable. When a virus invades anyone's cell, it may mutate every time it replicates. However, according to the general law, RNA virus will eventually develop into a mutant with low toxicity and exist for a long time, and then it will become influenza, but it will also produce a mutant with a sharp increase in toxicity due to some unexpected factors. Influenza virus is actually a coronavirus. At present, the toxicity of Omicron is not very great, but it is still much greater than that of ordinary influenza virus. It is predicted that in another 4-5 years, the toxicity of major epidemic variants will be reduced to the level of common influenza, and then it will be ignored.

Sixth, RNA virus is easy to mutate according to natural laws. If the virus wants to spread widely, its lethality will become lower and lower, and its infectivity will become stronger and stronger. Therefore, it will be very important to explore a future road of epidemic prevention. Now the virus has been effectively controlled under the zero eradication policy, but relatively speaking, the cost can not be ignored. I hope that the future policy can achieve the best of both worlds as much as possible, taking into account all aspects of the problem. RNA virus is easy to mutate according to the laws of nature.
