The community has been closed for a long time, why are there still infected people?

Although the community has been under risk control for a long time, this virus is latent, which means that although you are locked up here, although you are negative every time you test at the beginning, it does not mean that you will not have a positive situation. It is for this reason that we find infected people.

must isolate him, including his contacts and sub-close contacts.

All are subject to screening and isolation.

And the most important thing is that the virus is mutating all the time, so he may be incubated for a longer time, and when he first began to appear, everyone thought that he would be contagious within 14 days, which means that if he is not infected for 14 days, he will hardly be infected. But now it's different, it may take 21 days, or even longer, but there is no way for anyone to know for sure. Anyway, all we know is that the virus is very contagious, and it is particularly terrifying, and sometimes it is impossible to prevent it.

This community has been sealed for such a long time, and although these people say that they have not moved, it cannot be ruled out that they were infected before they were sealed here, but they have not been detected at that time. Sometimes you have to do a lot of nucleic acid to determine whether you are positive or not, so there is no way for everyone to be sure if there is a problem with these people they are locked up. The reason why all these people are locked in the community and not allowed to go out is actually to prevent them from carrying the virus, but they don't know it.

There are many people who are very incomprehensible about such things as isolation, and always feel that they are delaying their own affairs and making themselves particularly embarrassed. But what we have to know is that the reason why the country does this is also to protect us, so don't disobey the arrangement, if you find a problem, you must report it in time, don't harm yourself, but also harm others. Because sometimes if you get recruited alone, it may affect the people of a city.

Because the virus has mutated, it is not only highly contagious but also has a long incubation time, many people in home isolation have to go through multiple tests before they can find the virus, and there are asymptomatic infected people who turn positive, so there will be new cases every day.

There will always be outsiders coming in and out to deal with some things, and it may be staff, and then there will be an incident of infection, which is difficult to eliminate from the root.

I heard that it is transmitted between family members, this time the Omicron virus, the spread is fast, the insidiousness is high, especially the asymptomatic, as long as one person is infected positive, others will also be infected one after another.

The closure and control area refers to the residential community, natural village or unit or place where there are reports of positive ** infections in the past 7 days, and the prevention and control strategy is to implement 7-day closed management, regional closure, staying at home, and door-to-door service.

This must be judged according to the epidemic risk level in the county - in medium-risk areas, the epidemiological investigation and epidemic analysis of existing cases should be used as clues, and the places and personnel for prevention and control management should be reasonably determined according to the space and personnel in which they come into contact with their production and life, and fine management should be implemented.

For example, if there is an epidemic in the school in this area, it should be accurate to the class; If it is in a factory, it is necessary to accurately go to the workplace and workplace, and implement targeted prevention and control strategies in the village and households. In high-risk areas, in addition to the above-mentioned measures, it is also necessary to restrict the gathering of people and adopt control measures such as closed management to restrict the entry and exit of people.

Criteria for delineating risk areas

1. Region: Take the street or township as the basic unit.

3. Epidemic situation: how many new crown cases have been accumulated and whether there is a cluster of epidemics.

The classification criteria for high, medium and low risk areas of the epidemic are based on whether there are confirmed cases of the new crown in the street or community within 14 days and how many new crown cases there are, and the specific classification standards need to be appropriately adjusted according to the changes of the new crown pneumonia epidemic.

Because the epidemic in Shanghai is mainly based on the Omicron variant, the Omicron variant has a relatively strong insidiousness, so it will lead to the continuous emergence of infected people in Shanghai.

Although the communities in Shanghai have been closed for a long time, some communities still have confirmed patients, and some communities will also have a large number of asymptomatic infections. After that, the prevention and control work in the relevant communities will be further escalated, and people will also need to take nucleic acid tests every day to further screen for new crown pneumonia in this way.

The epidemic situation in Shanghai is inherently complex.

Since the outbreak of the new crown epidemic in Shanghai, the cumulative number of confirmed patients in Shanghai has reached more than 150,000. After that, the Shanghai area has urgently established a mobile hospital, and once new crown patients and asymptomatic infections are found, relevant personnel will undergo further examinations and **. Since then, asymptomatic infections have continued to appear in Shanghai, which has also led to the epidemic in Shanghai never reaching an inflection point.

This is mainly due to the nature of the epidemic in Shanghai.

The epidemic in Shanghai is mainly dominated by the Omicron variant, which is very transmissible and will also cause an incubation period of 3 to 15 days in many patients. During this period, although COVID patients have undergone nucleic acid testing, some may have missed tests, which has further led to many patients being tested positive for COVID one after another. <>

This is related to the screening mechanism of nucleic acid testing.

After the nucleic acid test is carried out, not all nucleic acid test results can be obtained at the first time, so new crown patients in some areas may be found after the nucleic acid test 2 to 3 days. After that, many asymptomatic infections in Shanghai will further spread the epidemic to those around them, which leads to many people who once had negative test results to be infected with the new crown pneumonia. If the epidemic is to be further prevented and controlled, the Shanghai area may need to further strengthen the intensity of epidemic prevention and control.

There is a certain delay in data delay, more transmission in households, and contact with contaminated items. The Omicron variant, which has strong insidiousness and fast spread, and items contaminated with the virus cannot be ruled out to cause infection after contact.

Because the Omicron virus is highly transmissible and latent, many people will only develop symptoms after being isolated at home for a long time, and there are many asymptomatic infections, and the community needs repeated screening to confirm, so the number of new people is more every day.

It is because there are many ways to transmit the virus, and some people have a weak sense of protection and physical fitness, and they are more likely to be invaded by the virus.

Now the epidemic situation is relatively severe, the virus is constantly mutating, and many patients are asymptomatic or have a long incubation period, so there will be new infections after the lockdown.

There may also be hidden chains of transmission, there may be cluster transmission, and there may be a delay in screening the data, and there may be positive samples after the test.

In the process of carrying out the epidemic work, there will always be some people who will disobey the discipline, which will lead to such a situation.

The risk of social transmission is relatively high, because many patients themselves will have a certain incubation period, which also leads to many people not being detected in the first place.

After the implementation of the measures of static management in Shanghai, although many communities in Shanghai have been set up as lockdown areas, residents in the lockdown areas will still be infected with yang**. The main reason for this situation is that the new crown epidemic in Shanghai has a certain insidiousness, which will cause many patients to spread the epidemic to the people around them. In addition, the epidemic in Shanghai will also have cluster transmission and family transmission, which is one of the reasons for the high number of confirmed cases in Shanghai.

During the lockdown period, there will also be positive ** dyers in Shanghai's communities.

In the prevention and control of the new crown epidemic, although many communities themselves belong to the closed and controlled areas, there will still be sporadic confirmed cases in the closed and controlled areas. After that, the community will conduct nucleic acid testing for all members of the community, and some patients themselves are asymptomatic infections, but the nucleic acid test results are negative. Because many patients have a certain incubation period of the virus, and the incubation period is even 3 15 days, it is relatively difficult to prevent and control the correlation in Shanghai.

The risk of social transmission in Shanghai is relatively high.

This is also said at this time, mainly because many patients themselves have an incubation period of 3 to 15 days. During the incubation period, although these patients cannot be diagnosed as soon as possible, they are still contagious in patients. When these patients come into contact with third parties, many patients can spread the epidemic further.

Residents in the Shanghai area need to further prevent and control the new crown epidemic.

While many residents in the Shanghai area are quarantining at home, there are still sporadic residents who are not strictly following these measures. For each of us ordinary people, we need to be as responsible for our own health and safety as possible, and at the same time, we need to actively respond to these epidemic prevention and control measures, and never take the prevention and control of the new crown epidemic lightly. <>

If you do not do a good job of self-protection in life, it is very likely that you will inadvertently be infected with new crown pneumonia, so you should also strengthen self-protection in life to avoid the risk of virus transmission.

The epidemic is an order, prevention and control is a responsibility, everyone should learn to pay attention to the epidemic situation in various places in life, only in this way can we better understand the relevant knowledge, improve our ideological cognition, avoid the spread of the epidemic, and generate hope. The epidemic in Shanghai has lasted for a month, which has had a great impact on the lives of local residents, and I believe that with the continuous efforts of all relevant departments and relevant personnel, the epidemic in Shanghai will be brought under control.

What is the risk of social transmission of COVID-19?

Shanghai is a first-tier city with a large flow of people, and the epidemic situation in Shanghai presents the characteristics of regional clustering and city-wide sporadic coexistence, and there is a potential risk of social outbreaks, so the local relevant departments should also take more decisive and resolute measures to reduce the flow of people and ensure that the spread of the epidemic is reduced.

How should we ensure the normal life of residents during the epidemic?

In the face of the epidemic, everyone should prepare some materials, and the local relevant departments should also increase the organization of the supply of goods, actively coordinate the co-insurance enterprises, further broaden the procurement channels, and avoid social panic caused by the lack of food and clothing. When you go out, you should wear a mask and do a good job of personal protection to avoid affecting local epidemic prevention and control due to personal behavior.

It can reach 80% because the virus has completely mutated, and the virus spreads very quickly, and there are many asymptomatic infected people, and some of them are affected by overseas goods and express packaging.

For this problem, then I think the relevant departments can make a targeted decision to improve, and the risk of social transmission is still relatively high.

The risk of transmission is particularly high, and now there are still positive infections in Shanghai during the risk control period, indicating that the epidemic prevention and control work is a big problem.

Because the new crown epidemic in Shanghai has a certain lag, when nucleic acid testing is carried out, the nucleic acid data itself will also lag, which leads to the fact that many communities in Shanghai still have positive ** infections.

After the implementation of the basic measures of static management in Shanghai, many communities in Shanghai have been set up as lockdown areas. During this period, residents in the community will not be able to go out normally, and many will further respond to the home quarantine measures. In this case, there will still be a series of positive ** infections in Shanghai, and some people will also become asymptomatic infections, which is mainly related to the characteristics of the new crown epidemic, and I will elaborate on it from the following points:

The Omicron variant itself has a certain incubation period.

The new crown epidemic in Shanghai is mainly based on the infection of the Omicron variant, which has a certain incubation period. After being infected with the Omicron variant, many patients may not test positive for 3 to 15 days. It is precisely because of this that there is a steady stream of yang ** dyers in Shanghai.

Nucleic acid testing in Shanghai itself will also lag.

In the process of nucleic acid testing in Shanghai, the nucleic acid test results in many areas cannot be obtained in the first time, and the nucleic acid screening itself also needs to be processed by the staff urgently. Especially in those areas that require a large number of nucleic acid tests, the results of some areas may not come out until the third day, which also leads to many asymptomatic infections not being detected in the first place. <>

This is also related to the cycle of the pandemic itself.

When the pandemic first broke out, it could not be contained in a short period of time. But if the number of confirmed cases of the new crown in a region has exceeded 10,000, it will be difficult to completely prevent and control the new crown epidemic at this time. It is precisely for this reason that the Shanghai area needs to further increase the intensity of epidemic prevention and control, and residents also need to actively cooperate with these epidemic prevention and control efforts.
