Why do a large number of asymptomatic infections continue to appear in China?

With the continuous development of the epidemic, a large number of asymptomatic people have appeared in Jilin, China, and the reason for this phenomenon is mainly caused by the following reasons:

The impact of the virus will continue to decrease. According to relevant experts, the greater the impact of the virus, the lower the transmissibility, but the smaller the impact, the higher the transmission of the new coronavirus.

It has been three years since the beginning of the development, and the impact of continuous changes has become lower. Most of the people diagnosed with the disease basically do not feel any discomfort, and only some elderly people with underlying medical conditions will have fever.

Symptoms such as cough or muscle aches. If you don't pay attention, you can have a large number of asymptomatic people in a short period of time.

It is difficult to detect the absence of symptoms, so a large number of asymptomatic people are affected. Except for some elderly groups with some obvious symptoms, most young people have no obvious discomfort after getting the new crown, and can still commute to work normally, if they do not do a good job of personal protection and do not wear masks during this period, it is very likely that they will carry the virus to others. In just a few days, the upward trend in the number of asymptomatic people will usher in a peak, through nucleic acid testing.

There will be a slow downward trend in the future.

The vaccination rate is high, and the body has basically no symptoms. The number of vaccinated people in our country has now reached 1 billion, although the new crown vaccine.

It is not possible to guarantee 100% of people's safety, but according to relevant experts, the ability to resist the virus can reach 70%, and even if people get the new coronavirus, there are basically no uncomfortable symptoms, which is why a large number of asymptomatic people may appear in a short period of time.

In general, there is an obvious essential difference between the number of asymptomatic people and the number of confirmed cases, and the number of asymptomatic people is often not counted when China counts the number of confirmed cases. This also shows that asymptomatic people can return to normal as long as they are isolated as required, and at the same time avoid adding a lot of potential risks to others.

There are more asymptomatic infections than confirmed cases of the local new coronavirus in our country. With the enhancement of early detection capacity across China, the goal of nucleic acid testing in China is to complete the task of nucleic acid testing in the designated region. The latest deployment of nucleic acid screening has enabled all parts of China to find infected people in less time and control the source of infection as quickly as possible.

Many infected people were detected much earlier than in the past when they were found with fever and dry cough in designated medical facilities.

Our residents have been vaccinated on a large scale, and the level of nucleic acid testing in China has increased compared to the beginning of the coronavirus, and the frequency and number of nucleic acid tests have increased significantly, which has helped to detect people infected with the new coronavirus in a timely manner. This is also one of the reasons for the increase in asymptomatic infections. As the denominator of nucleic acid testing increases, so does the numerator of nucleic acid positive cases.

Despite the many asymptomatic infections, China has a high vaccine penetration rate. Yes**, the likelihood of an asymptomatic infection evolving into severe illness is very low.

We still need to do a good job of vaccination, and strengthen the prevention and control of the epidemic for individuals and families. Asymptomatic infections are not confirmed cases, so they are not newly infected, but asymptomatic infections can also be a source of infection with some risk of transmission. Asymptomatic infections and close contacts should also undergo 14-day centralized isolation medical observation.

The high number of asymptomatic infections is a clear feature of this round of the epidemic. Zhang Boli, an academician of the Chinese Academy of Engineering, said in an interview with reporters that this feature is not only related to the virus itself, but also related to timely screening and early detection of infection, and is closely related to vaccination.

People who are asymptomatic should not be taken lightly. Although asymptomatic, they are still contagious and more insidious, with no symptoms today and symptoms tomorrow, and the coronavirus virus gradually weakens its lethality as it continues to spread. Hou Jinlin, a well-known infectious disease expert, has confirmed this view.

The virus enters the body from an intermediate host and begins to spread through the population. The first generation of infected people are like the vanguard of war, and they pay the highest price.

There will be contact with some outsiders and some other countries, or they may not be vaccinated. This is not the case without very good resistance and immunity. Their own quality is particularly poor.

The speed of asymptomatic transmission is very fast, and asymptomatic infections cannot be detected at the first time, so there are many asymptomatic infected people.

I think it's mainly because of the mutation of the strain, and then the vaccine has a certain effect, so the disease has been reduced a lot.

Asymptomatic infection is a concept that has always existed in infectious diseases - there are no symptoms, but they have positive indicators of etiology, and some people will also have our antibody response. If a person is infected with the virus, has no symptoms after a period of time, and finally turns negative with nucleic acid, it is an asymptomatic infection. In this case, we think that the natural process of his illness has been completed, and he has been asymptomatic during the completion of the process, which is called asymptomatic infection.

It must have been obtained from a certain place, and there must have been a history of contact, but it is just that the history of contact can you find it very clearly. But how contagious asymptomatic infected people are, there are not many reports now. If a person is infected with the virus and does not get sick, first of all, he is in good health, secondly, the virulence of the virus is relatively weak, and thirdly, the number of viruses he has been exposed to is relatively small, so he may not get sick.

The contagiousness of asymptomatic infected people will definitely be low, but how low it is, or whether it is already low enough to be gone, really needs to be observed. We now say that as long as there is a positive test, we attach great importance to it and have to do some isolation measures. He will stay in the isolation point for 14 days, and if he is in the isolation point, he will be tested twice to ensure that he is indeed negative, and then he will be released from isolation.

So basically, they don't have a chance to infect other people, that is, whether he is contagious or not, we still treat this kind of confirmed patient. Asymptomatic infected people may need to have a full physical examination if they are to be truly screened. The physical examination needs to check nucleic acid, a blood routine is required, and we also recommend that a lung CT be done if possible.

Asymptomatic infections refer to patients who have not developed symptoms related to the new coronavirus after being infected with the new coronavirus through droplet transmission and contact transmission due to the type and number of invading viruses and the patient's own immune system response, but it should be noted that asymptomatic infections are contagious.

Generally, it is due to the patient's own righteousness is relatively sufficient (usually the body's immunity is relatively strong, and it is not easy to get sick), the human body itself has righteousness, external evil attacks, righteousness and evil qi are opposed, the winner generally does not show symptoms, and the loser generally shows symptoms.

The virus is constantly spreading, and the natural tendency to mutate is to become less and less virulent and mortal.

It will gradually decrease, but the contagiousness will gradually increase.

In fact, it is not difficult to understand that although the virus is small, it has the same purpose as the existence of organisms in nature, which is to perpetuate their genes. If the host dies too quickly, it will also cause the virus in its body to die; If the host symptoms are too severe, they are quarantined**.

Whether the host dies or the symptoms become too severe, neither outcome is conducive to the spread of the virus. Therefore, the trend of virus mutation will develop in the direction of low case fatality rate and mild symptoms. In general, the virulence is decreasing and the infectivity is increasing.

The specific manifestation is asymptomatic infection.

More and more. <>

Maybe in the future, the coronavirus.

It could be like the flu.

It will persist in human society for a long time, but the lethality may become as low as the flu.

However, at this stage, it is still the early stage of the spread of the new coronavirus, and the case fatality rate is still very high. Moreover, it cannot be ruled out that after infection, the virus will produce an "atavistic phenomenon" and mutate back to high virulence, so everyone cannot report that there is a fluke mentality, and strengthening self-protection is still the top priority.

Asymptomatic infection, is it a new term that is newly discovered and heard, in fact, the noun is not new, the virus has long existed, the virus evolution and mutation are cunning, it is very hidden, so that human beings can not be careful, what a dangerous and terrible virus, people mention this virus, people feel numb. The virus is not easy to detect and overcome, and the person infected with the virus will develop an antibody that has no feelings for himself, but he will infect more people.

If asymptomatic infections remain high and gradually rise, it will bring catastrophic consequences to human beings, symptomatic viruses are clear and clear, people often say, open guns are easy to dodge and dark arrows are difficult to prevent, asymptomatic and will infect people of the virus, this is the most terrible and dangerous virus, this is the silent bomb buried around us, the bomb is not loud and powerful, its lethality and destructive power is much higher than the time bomb, screening and inventory of this asymptomatic infection, to rely on the efforts of virology experts, relying on the joint efforts of the whole people and the whole society.

Let's look forward to the early development of a vaccine to save the world.

Yes, indeed, because the weather is very hot these days, the virus is very afraid of high temperatures, and as soon as the weather is hot, the virus will slowly disappear.

Yes. The virus is no longer as virulent as it used to be, and people infected with the virus no longer have as many symptoms.

Asymptomatic infections.

There are many reasons for this, and it has to do with a variety of factors.

Asymptomatic infections are due to the strong immunity of the body, and after the virus enters the body, it is engulfed by immune cells, and then antibodies will be formed to produce special immunity, which can avoid the body from being reinfected with the new coronavirus.

So the patient did not develop the new coronavirus.

The symptoms are called asymptomatic infections. Secondly, asymptomatic infections may also be due to the fact that the virus in the body is still in the incubation period, and once the incubation period has passed, clinical symptoms such as fever, dry cough, fatigue, and dyspnea will appear. Asymptomatic infections generally do not show other discomfort, and a small number of patients may be accompanied by symptoms such as general weakness and mild cough.

You can exercise more in your daily life to enhance your physique and resistance.

This is easy to understand, for example, everyone has a cold that has mild and severe symptoms. It is common sense that the pathogenicity of the virus will gradually decrease over time.

Relate. The new coronavirus variant is more contagious, and the virus is relatively weaker. The clinical manifestation of the weakening of the virulence of the virus is that the clinical symptoms will be milder, and many infected people do not show clinical symptoms for a short time after infection.

But despite this, asymptomatic people should not be taken lightly, and although they are asymptomatic, they are still contagious and more insidious. And it's possible to be asymptomatic today, and maybe you'll have symptoms tomorrow.

It's not like this, the main thing is that many people in my country have been vaccinated, and it is a booster shot, and now there are probably more than 90% of people who have built an immune barrier! And not that the virus has weakened! It's just that after vaccination, the relative symptoms are reduced!

Therefore, even if you are vaccinated, you must strengthen self-protection and other related epidemic prevention measures!

No, it is related to the increased contagiousness after the virus mutates, because asymptomatic infected people are screened through nucleic acid, which does not mean that they will not show symptoms in the future.

What are "asymptomatic" and "asymptomatic infection"?

"Asymptomatic" means that the patient does not feel any discomfort in person, and the doctor's physical examination and related auxiliary examinations (such as blood routine examination, chest X-ray, etc.) do not find any pathological conditions. "Asymptomatic infection of the new coronavirus" refers to the infected person who does not have any painful sensations (such as fever, cough, sore throat, etc.) after being infected with the new coronavirus, and the doctors and nursing veteran bureaucrats have not found any pathological signs and indicators, but their respiratory tract and other specimens have tested positive for nucleic acid testing or antibodies.

Who are the "asymptomatic" susceptible populations?

All groups of people are susceptible to COVID. According to the "New Coronavirus Asymptomatic Infection Management Specification" issued by the joint prevention and control mechanism, there are five categories of people who need special attention. First, close contacts of new crown pneumonia cases; Second, close contacts of cluster epidemics, such as two or more people who become ill in a small area such as airplanes and trains, and their close contacts need to be isolated and investigated; the third is the exposed population found in the process of tracing the source of infection of new crown pneumonia cases; Fourth, people who have a history of travel and residence in areas where new crown pneumonia cases continue to spread at home and abroad, in different periods, the state will release different objects that need attention, such as focusing on Wuhan in Hubei Province at the beginning, and now paying more attention to the hard-hit areas abroad; Fifth, relevant persons identified in epidemiological investigations and opportunistic screening.

How contagious are "asymptomatic infections"?

At present, people are still in the process of understanding the contagiousness of "asymptomatic infections" of the new coronavirus, but there have been some cases that can confirm that "asymptomatic infections" are indeed contagious. In general, "asymptomatic infections" are less contagious than confirmed patients. At present, the state has adopted very strict isolation measures for "asymptomatic infected people", so there is no need to panic too much about "asymptomatic infected people".

How can individuals prevent the risk posed by "asymptomatic infections"?

One of the ways to prevent "asymptomatic infections" is to discover the source of infection and cut off the route of infection. If you find that the people around you are from the epidemic area but have something to hide, you can take the initiative to report it. In addition, it is more important to do a good job of personal protection, abide by the rules formulated by the national epidemic prevention and control, do a good job in patriotic health campaigns, protect yourself and your family, ventilate your home, wash your hands frequently, wear a mask in public places, and keep a certain distance.

In addition, there is no need to panic excessively about the epidemic and "asymptomatic infections", and maintaining a good mood can improve the body's resistance.
