Why does the epidemic recur? Is it related to the international environment?

As the old saying goes, a pandemic will only last for three years. This epidemic has been with us for some time. Someone asked, why is the epidemic repeated? It's under control. Why did it suddenly appear again? Academician Zhong Nanshan gave the reasons: First, the influence of the international environment; One is that the strain is more active; One is because of some people.

First, the international environment has put pressure on our epidemic prevention and control.

We take effective measures to deal with the epidemic, whether it is silent or dynamic clearance, we do well, but sometimes we meet different "teammates" when we do well. This "teammate" is an international friend! In their country, there is no such thing as prevention and control. Their knowledge of the epidemic is more about catching a cold or wearing a mask. As for nucleic acid detection, it is not as strict as we are, nor as frequent as we are.

Even if the nucleic acid test is positive, there is no effective prevention and control. They just went to the hospital according to the procedure. As for whether there will be human transmission, it seems that they don't care. It seems that the COVID-19 epidemic is just an ordinary cold, and the way to deal with it is very simple. Their ideological neglect led many people to be infected by COVID-19.

Some people just test positive for nucleic acid, which is what we call asymptomatic infection, and their activities are not affected. Sometimes, I will travel or work abroad. For other countries, it brings the pressure of prevention and control. Some people will come to our country, so it may lead to the recurrence of our epidemic. For us, we can't refuse outsiders, because we need to open our doors if we want to connect with the international community.

People flow is one of the reasons for the recurrence of the epidemic, as well as the problems brought by the cold chain. Many foods are imported from abroad, and foreign foods are packaged or processed by foreigners. Foreigners may be asymptomatic, so some foods may include COVID-19. They didn't know that the food was shipped to China, and the testing of these foods was not complete. That will put pressure on our epidemic prevention and control.

Second, viruses are very active and more difficult to deal with.

COVID-19 has mutated. Although we have been working hard to develop vaccines, we are also vaccinating. However, the mutation rate of the virus is beyond our imagination. They have mutated from the original strains into many kinds. We are familiar with Alpha, Beta, Delta, Omicron and so on. Even Omicron strains have different degrees of variation, which brings great pressure to our epidemic prevention and control.

The mutant strain is more contagious, and the previous transmission may be due to contact with food or other items of the strain, so it can be transmitted. With the variation of the virus strain, its spread is more subtle, and the droplets of asymptomatic infected people can also be contagious. In the face of disease strains with such rapid mutation rate, our prevention and control pressure is naturally not small.

The methods we adopt include wearing masks, washing hands frequently, keeping a good distance of one meter, and not gathering. All these are effective ways to prevent the spread of the virus. As the saying goes: wise people worry too much and sometimes suffer. No matter how effective our prevention and control is, there will inevitably be some negligence, strains will also invade, and our prevention and control pressure will increase a lot. Sometimes, the epidemic will suddenly break out in some places, which makes people unprepared.

In addition, the European Medicines Agency (EMA) issued a warning, or a "brand-new" COVID-19 strain appeared, which increased the pressure on our epidemic prevention and control. Because of the spread of virus strains, especially aerosol transmission, we can't prevent it. We don't want the epidemic to spread like this, but the reality is that the strain mutates too fast.

The spread of the virus has brought a lot of trouble to our lives. Sometimes, it will also affect our lives. Some people think that since the epidemic cannot be prevented and controlled, it is better to let go, so as to realize the survival of the fittest, which is also a measure of social development and progress! People who think like this are not very good, because all people are created equal.

Third, the personal behavior of some people has greatly increased the pressure of prevention and control.

Some people think that epidemic prevention and control cannot be achieved, so it is better to let go, just like abroad. But the national conditions are different, so we can't copy them mechanically. Some people did whatever they wanted, and as a result, there was pressure for prevention and control in some areas, and I was punished. Even so, some people don't care.

Some deliberately concealed the epidemic and visited relatives and friends' homes, causing relatives to be implicated; Not only that, there are people who hide the fact that nucleic acid is positive in order to play mahjong. As a result, many people are involved. What these people have done is only for themselves, without considering others or the overall situation of our epidemic prevention and control.

Some people have negative nucleic acid tests, but they don't know it, but they go to other provinces to play, which makes the epidemic prevention and control in many places greatly increase the pressure. These actions are irresponsible; The actions of these people are also illegal. In accordance with the relevant provisions of the Public Security Punishment Law, it will be punished. The purpose of punishment is to let these people know that the epidemic is no small matter, and it is the obligation of every citizen to protect themselves and their homes.

Some people think that such a selfish person should be severely punished. After all, epidemic prevention and control is a major event, and we can't let everyone collectively guard because of the behavior of some people. Some people may do this because they think it's okay. But the result has caused trouble for everyone. What do you think this kind of person should do? Welcome everyone to leave a message!
