▶ Guangzhou Haizhu: Lift the temporary control measures in some areas

According to the progress of the epidemic disposal, after a comprehensive research and judgment of the expert group, the new crown pneumonia's epidemic prevention and control headquarters in Haizhu District decided to lift the temporary control measures on the 13th, 15th, and 17th of Renhou Street, Haizhu Street, from 14:00 on September 12, 2022. Implement normalization prevention and control measures.

▶ Jiangmen Taishan: Temporary control of the whole region of Taicheng Street

According to the news of Taishan, on September 11, a case of nucleic acid testing in Taicheng Street, Taishan City, Jiangmen City, Guangdong found abnormalities. The new type of coronary virus pneumonia's epidemic prevention and control headquarters decided to implement the following temporary management and control measures in the entire region of Taicheng Street, Taishan City.

The control measures are as follows:

1. Strict management of community communities and urban villages. Various types of mounts are on duty for 24 hours, strictly executed body temperature, masks must be worn, check 24 -hour nucleic acid negative proof or 24 -hour nucleic acid sampling records, residents must scan the "place code" in entering and exit. Negative proof. Residents of non -community and villages in the city declined to enter.

2. All takeaway, express delivery, etc. do not enter the community and villages in the city, and implement no contact distribution. In the entrance and exit of the community community, the designated area of ​​the designated areas of the city, the takeaway express employees shall be responsible for the organization of "one -day inspection" and health. declare.

3. Strengthen the management of the place. Cultural entertainment, sports fitness, bathing, beauty hairdressing, accommodation travel industry, supermarkets, farmers' markets, scenic spots and other key places and closed places must strengthen staff health monitoring and management, strictly implement body temperature must be measured, health code must be checked, place code All preventive and control measures such as scanning, masks must be worn, places must disappear, and must -have, and must be displayed at 24 hours of nucleic acid negative proof to be present to reduce personnel gathering.

4. The production enterprises and construction sites of Taicheng Street strengthen the prevention and control of the epidemic. All personnel must implement the "three percentage" (100 % temperature test, 100 % mask, and 100 % scan code bright code). Organize employees to conduct nucleic acid testing in batches according to the government arrangements, and preferential arrangements for delivery personnel will give priority to nucleic acid testing. All employees' homes and units are "two points and one line".

V. Residents in the jurisdiction to enhance personal protection awareness, orderly cooperate with epidemic prevention operations, and carry out all -employed nucleic acid testing as required to ensure that "inspection must be checked and one person should not be lost" (follow -up according to needs to determine the frequency of nucleic acid testing). Implement prevention and control measures such as "temperature measurement, scanning code, and wearing masks", and do a good job of self -health monitoring. If symptoms such as sore throat, dry cough, fever, fatigue, and decreased smell are reported, they will report to the community immediately and go to the clinic of the clinic nearby. During the consultation, we must strictly do personal protection, wear masks correctly, and avoid taking public transportation.

The above measures will be implemented from now on, and then dynamically adjust according to the epidemic prevention and control situation. Enterprises and individuals who do not fulfill their main responsibilities and refuse to implement epidemic prevention, will be held accountable in accordance with the law.

Why does the new crown epidemic in my country have been here one after another?

National Disease Control expert answer

In response to the recent situation of new crown pneumonia's epidemic, on September 9, 2022, Wu Zunyou, chief expert of epidemiology of the China Centers for Disease Control and Prevention, posted that recently, the epidemic of new crown pneumonia in my country has risen one after another. In the surrounding environment and mutant virus.

Among them, the new challenge facing "internal prevention and rebound "-

The emergence of Omikon's mutant strains makes hidden communication more common, and it also increases difficulty to prevent control. The hidden communication also covered the "mysterious" color to the spread of the new crown.

Our understanding of hidden communication is still very limited. It is not clear how the hidden communication happens. Whenever you can't find the source of the source, you can attribute to "hidden communication".

Some time ago, Professor He Dayi, a well -known Chinese medical scientist in the world, reported that the new crown case was "cured" and the phenomenon of spreading was deserved.

He reported ten cases of new crown -infected people to take Pfizer's new crown special medicine for 5 days (the standard treatment for the treatment was 5 days), the symptoms of the fourth day disappeared, and then sampled twice on the 5th and 7th day on the 5th and 7th day. Test that nucleic acids are negative. The patient healed "recovery". He did not stop observing, but continued to detect nucleic acids for a period of time every day. He found that three of them had nucleic acid positive after discontinued nucleic acid negatives, and it was also transmitted to other members of the family.

If these cases are not for the purpose of scientific research, they may not be able to find them "Fuyang" for a period of time, and the infected people who have been spread by them will become "hidden communication" without the source of infection.

Similar phenomena have actually been discovered in China. At the beginning of last year, a new crown epidemic survey was launched in a province. Among the several key personnel locked, nucleic acids, IgA, and IGG testing were performed daily, and the results of the results of individual nucleic acid testing were negative and positive. After emphasizing sampling quality, there is still a phenomenon of negative and positive nucleic acid negatives.

Similarly, similar situations were found during the Beijing Winter Olympics earlier this year. In the daily nucleic acid detection for more than ten consecutive days, each infected person has a negative and positive interval between multiple infected people with 3 to 5 consecutive nucleic acid detection results, that is, the nucleic acid test result of the day before the nucleic acid test is negative. And each nucleic acid detection positive CT value is below 35, which can basically exclude false positives. Detectors participating in the Winter Olympics have been strictly screening, training and assessment, especially after 1-2 times negative and positive alternation occur, and they will be more careful. Moreover, these test results were jointly analyzed and discussed by the expert group. Therefore, the possibility of sampling and detection operations can basically be eliminated. In other words, the phenomenon of negative and positive alternation of this infected person infected is objective.

If these infected people do not do nucleic acid testing every day, it is particularly coincidental. In ordinary life, these people caught up with the negative day to do nucleic acid testing, and the nucleic acid test was not performed on the day. It is negative, and the infected person who caused the spread on the day of positive becomes "hidden communication".

As for what causes the phenomenon of negative and positive alternating nucleic acid test results in the new crown infection, it is unclear, and further research needs to be done. This kind of negative and positive phenomenon is to play a role in "hidden communication", and further research is needed.

The existence of this phenomenon undoubtedly brought huge challenges to the new crown prevention and control.
