How does high temperature affect the spread of virus?Why should I frequently "3 days and 2 inspections"?Look at the hot topic ten questions

Facing BA.5,

Is it still useful to wear masks and vaccines?

Shanghai continues to high temperature,

What impact does it affect the spread of virus?

All found in isolation control,

Why is there a new risk zone?

Recently, the 10 epidemics related hotspots that citizens are concerned about, barista sorted you to answer the answer

ask

Some researchers said that BA.5 is currently the strongest strain with the strongest propagation, and the immune escape ability has also improved. New poison strains are coming, is it still effective to wear masks and vaccines?

answer

Yuan Zhengan, a member of the expert group of the Shanghai Epidemic Prevention and Control Work Group, said that the spread of Omikon BA.5 mutant strains is mainly droplet transmission. Personal hygiene) and "five protection" (the mask should be worn, the social distance must be left, the cough and sneezing must be covered, the hands should be washed often as possible). One of the effective prevention and control measures.

Research data at home and abroad shows that the spread of the BA.5 mutation plant is accelerated and the immune escape ability is improved. However, compared with the previously popular Omikon mutant plant BA.2, the risk of critical illness and mortality rate of disease occurred without the risk of severe illnesses and mortality rates. Discover obvious differences. The research results also show that vaccination can still effectively prevent critical illness and death after BA.5 infection. Especially for the elderly with basic diseases, they should actively vaccinate the new crown vaccine.

ask

Recently, Shanghai has continued to have high fever. What impact does the heat spread on the spread of the virus? What should citizens pay attention to when doing nucleic acids?

answer

Under normal circumstances, in an environment of 56 ° C, the new crown virus will die within 30 minutes, and the higher the temperature, the shorter the virus survival time, but the summer heat does not reach the temperature that causes the death of the new crown virus. In the sweltering weather, if the citizens take off the mask to breathe at will in public places, they will spread the virus to take advantage of the opportunity.

In summer, high temperatures, high humidity, and sullenness of body sensation. Citizens pay attention to the measurement of sunscreen and heatstroke cooling during nucleic acid testing. It is recommended to avoid going out at noon. When waiting in line, do not take off the mask at will because you are afraid of heat and boredom. However, if you have discomfort such as dullness and shortness of breath, you should immediately go to the open ventilation place to remove the mask.

It is hoped that citizens to do the first responsible person of their health, actively abide by the relevant relevant epidemic prevention regulations and requirements, and implement the "three -piece epidemic prevention" of "scientific wearing masks, maintaining social distance, and paying attention to personal hygiene". Three -piece set of new epidemic prevention ":

//

Regularly measure acid

Active scanning site code

Vaccine as soon as possible

ask

Some infected people are obviously found in isolation and control. Why are there still risk zones?

answer

Some of the positive infections found in some closed -loop management and control, after analysis and judgment, the risk of residential epidemic dissemination is large. According to the "New Coronary Virus Pneumonia Prevention Plan (Ninth Edition)", it is designated as a medium -risk area. It is also a mid -risk area. Some areas are only sealed in the building, and some of them are sealed in the entire community. The judgment standards may also be different.

Yuan Zhengan, a member of the expert group of the leading group of the municipal epidemic prevention and control work, said that the following factors are mainly considered: the living conditions of cases and asymptomatic infections (mainly include living conditions, living environment, surrounding conditions, etc.), and the risk of crowds in the region is exposed The status (mainly includes personal protection, crowd aggregation, frequent contact, etc.), the risk of transmission of cases and asymptomatic infections (mainly including work, activity time, scope, and the closed nature of related places, the length of the investigation interval, etc.), etc.) Depending on the specific situation.

ask

Why are there new positive infections every day in isolation control?

answer

Yuan Zhengan, a member of the expert group of the Municipal Epidemic Prevention and Control Work Group, said that according to the requirements of the relevant disposal, the investigation of people related risks of the positive infected persons, carried out comprehensive risk assessment, traced the abnormal symptoms of abnormal symptoms such as nucleic acid detection of positive infections or abnormal symptoms such as fever or fever. The relevant personnel and trajectories of heaven are implemented, and the corresponding control measures are implemented. At the same time, during the isolated control of risk personnel such as close contact, some personnel nucleic acid detection abnormalities were also found through regular nucleic acid screening.

Here, we also remind the general public to continue to adhere to the "three -piece set" and "five more", try to "do not get together" and "not gather". First, if the epidemic prevention personnel are inquired, they must fulfill the responsibility for epidemic prevention and inform truthfully. The event trajectory and other information; second, if the relevant health reminder SMS is received, follow -up control measures should be implemented in accordance with the content of the SMS, and personal protection is performed and the nucleic acid sampling test is performed immediately. Over -nucleic acid detection abnormal personnel should take the initiative to report to the community they are located, and cooperate with subsequent prevention and control measures.

ask

Recently, some citizens received text messages saying that "according to the relevant big data investigation, you may have the risk of direct or indirect contact with those infected with the new crown virus in the near future." What should the citizens do after receiving the text message?

answer

Wu Huanyu, deputy director of the Municipal Centers for Disease Control and Prevention, said that once a positive infection is found, the flow staff of the municipal and district disease control departments will adhere to "fast and fast", combined with on -site investigation and big data information, comprehensive analysis, scientific research and judgment, investigation, investigation, investigation, investigation The trajectory of the activity, locking the risk people, will send text messages to some people who may exist, asking them to perform a nucleic acid detection at the nucleic acid detection point as soon as possible, and then perform a nucleic acid detection at 24 hours, that is, 2 screenings should be completed within 3 days. Essence

Citizens are requested to actively cooperate after receiving the prompt SMS and implement nucleic acid testing in accordance with the requirements. This is to protect yourself, protect your family, and protect others in order to discover the epidemic in early and take measures to prevent more people from being infected. At the same time, everyone must continue to tighten the epidemic to prevent and control this string. Do not pile up, do not gather, do a good job of personal protection, standardize wearing masks, maintain social distance, and effectively achieve the "three -piece set" of epidemic prevention. When entering and leaving in public places Epidemic prevention requirements for scanning areas to jointly build a dense epidemic protection network.

ask

In many districts in Shanghai, the screening of all -staff nucleic acid has been carried out recently. The principle is based on the principle of "completing 2 nucleic acid tests within 3 days and at least 24 hours."

answer

The infection of Omikon's mutant strain has a incubation period, which means that there is a process of virus replication, and the virus replication volume can be detected after reaching a certain level; and the human body has immunity itself. Therefore Nucleic acid testing as an objective indicator, infected people can be found in the big population as soon as possible, blocking the source of infection; in addition, the current nucleic acid detection method is mainly to extract the virus RNA in the sample. Real the amount of virus that can be amplified.

At present, the new coronary virus nucleic acid testing kit used by Shencheng is a "dual target", which can not only detect conservative sites, but also cover the mutant site. Therefore, it is still effective for the recently appeared Omikon BA.5.

Therefore, continuous and interval between 24 hours of screening can be found in society as soon as possible and as soon as possible.

ask

What are the isolation and control measures for immigrants in this city? Can I go out during health monitoring?

answer

According to the Civil Affairs Bureau, in accordance with the ninth edition of the national prevention and control plan, the city implements the "7+3" isolation control measures for immigration personnel. That is, if the immigration destination is the city, a fixed residence and meet the conditions of home health monitoring, the "7 -day centralized isolation medical observation"+"3 Heavenly Home Health Monitoring" measures are implemented.

During the home monitoring, the relevant districts and streets and towns have strictly reviewed the fixed residences of entry -minded personnel in this city. Concentrated isolation. For those who meet the conditions, a special vehicle is arranged from the district where the centralized isolation point is located to transfer it to the place of residence, and the community "three -person group" (community workers, community doctors and community police) monitor. On the third day of home health monitoring, the community arrangement of sampling personnel to come to the door or transfer to a special car to the designated medical institution to implement nucleic acid testing.

Do not go out during the home health monitoring of the entry staff. For special circumstances such as medical treatment, we must do personal protection when going out, standardize the N95/KN95 mask, and avoid taking public transportation. In addition, during the home health monitoring, the Land Village Committee issued the "Notice of Home Health Monitoring", informing the relevant requirements of home health monitoring and registering. By establishing WeChat groups and other methods, regularly inquire and collect information on the body temperature, symptoms of home health monitoring personnel twice a day, if you find that there are symptoms such as fever, dry cough, fatigue, sore throat, smell (taste), diarrhea and other symptoms, etc. Report immediately, and contact the 120 negative pressure first aid vehicle by a special person to send it to the clinic or designated medical institutions for medical treatment.

ask

Under normalized epidemic prevention and control, in addition to the "three -piece set" and "five more", why should you emphasize the "new epidemic prevention three -piece set"?

answer

New crown virus vaccination can greatly reduce the risk of severe diseases and deaths. In countries or regions where viruses continue to be popular, the elderly and people with basic diseases are priority to vaccinate people. After the elderly complete the basic immunity of the new coronal virus vaccine, even if infection, the risk of developing severe illnesses will be at least 60%. If the enhanced needle is also vaccinated, the risk will be reduced by more than 90%.

The results of nucleic acid testing are the "gold standard" of diagnosis of new coronal virus infection. Coupled with normalized nucleic acid testing and screening as required to ensure that "inspection should be inspected", those who can screen early infection as soon as possible, as soon as possible, and lock the risk areas and key groups to block virus transmission, block virus transmission chain.

The place code is an important technical means for precision prevention and control. Sweeping the site can automate the information of all personnel in and out of the place. At the same time, the health status can be verified, which helps strengthen the traceability and monitoring of the epidemic and protect personal information.

ask

At present, nucleic acid testing is relatively frequent. Does the testing of the test use affect human health?

answer

The sample swab looks similar to ordinary "cotton swabs", but the top is actually a velvet swab. The velvet swab is made of nylon fibrous velvet technology. The front end is painted with short fiber fixed in vertical mode, so that there is no absorption hole in the collection area of ​​the entire collection swab. In this way, the collected samples will not be decentralized to stay in the fiber, which is conducive to faster and more efficient sample elution.

Nucleic acid testing uses medical supplies. Its production environment and requirements are very strict. There are also relevant standards for quality supervision. Please rest assured that nucleic acid testing has no damage to the human body.

As for some public sampling, there will be a disgusting response. The reason may be that the pharyngeal sensitivity of different people has different throat and tolerance; the scraping of the pharynx during the sampling process will cause itching or vomiting; in addition, when sampling Some people will be combined with the roots of the tongue. The sampling person must ensure the sampling quality, and they will explore in it and find the posterior wall and tonsils. At this time Feeling is easy to relieve. ask

According to the monitoring information of the China National Influenza Center, since June and July, the positive rate of influenza virus detection in the southern provinces has risen, and some provinces have been in the high incidence of summer, and the influenza health prompts have been issued one after another. How to distinguish flu virus pneumonia? How to prevent the flu in summer?

answer

Guo Xiaoyan, chief physician of the Department of Lung Diseases, Affiliated to Longhua Hospital affiliated to Shanghai University of Traditional Chinese Medicine, introduced that the respiratory infection caused by flu virus caused by flu virus is generally manifested as acute onset and fever (some patients can reach 39 ° C). Muscle, joint soreness, extreme fatigue, loss of appetite, and other systemic symptoms. There are often symptoms of nasal congestion, runny nose, vomiting, and diarrhea. Some influenza severe cases will cause serious complications such as viral pneumonia, acute respiratory distress syndrome, etc., and life is life -threatening. Do not take it lightly.

New coronal virus pneumonia is infected by the new coronary virus. Due to the continuous mutation of the new coronal virus strains, especially the popular Omikon virus strains, which are more hidden and more spread. Infected patients are mainly asymptomatic and mild. This is similar to the symptoms of mild flu. It is not easy to distinguish. It needs to be identified according to the history of epidemiology, new coronal virus antigen testing or nucleic acid detection.

For influenza, inoculation of influenza vaccines to prevent influenza or serious complications of influenza, the most effective and most economical method. Those who are more than June and have no contraindications can vaccinate the flu vaccine. Children, pregnant women, elderly people, and people with chronic basic diseases are high -risk groups who are prone to complications. It is recommended to take priority to vaccination of influenza vaccines.

In addition to vaccination, we need to develop good personal hygiene habits, wearing masks, shampooing hands, and avoiding crowds; windows in the room open more windows to maintain air circulation; strengthen exercise to ensure full sleep. If there are abnormal symptoms such as fever and cough, the kidney consultation will be issued in time. It is diagnosed as flu. It is recommended to be isolation at home, pay attention to rest, reduce cross -infection, and closely observe changes in the condition. If the symptoms of influenza are not significantly improved or aggravated, you need to seek medical treatment in a timely manner.
