The joint prevention and control mechanism of the State Council held a press conference and said: The infected people reported in Zhuhai, Guangdong on January 14, the infected people reported in Zhongshan, Guangdong, on January 13, and the infected people reported in Shanghai on January 13, the gene sequencing in these three places is the Aomi Kerong variant strain.
On the evening of January 13, Shanghai reported 2 new cases of locally confirmed cases and 3 cases of local asymptomatic infection. Three of them worked in the same milk tea shop.
Milk tea shop customers come and go, how to determine the close connection and sub-close connection? Also buying milk tea in the store, why one more action will make you quarantine for 14 more days? Let's follow the investigators, call up the surveillance screen, and see what happened between the positive case and the customer.....
In the surveillance footage, although many people have the habit of wearing masks, it is often regrettable and even angry that people "wear a lonely" and finally suddenly "drop the chain", increasing the number of close contacts.
For example, there are two customers who go to buy a drink together. After ordering, he deliberately avoided the crowd in line and went to the corner to wait.
Originally, these two people were judged to be high-risk screening (high-risk screening objects), who expected the plot to suddenly "reverse", one of them may have felt that the store was hot and took off the mask, and also went to get a meal, and chatted with the positive personnel.
In this case, the two can only be judged to be closely connected. According to the current epidemic prevention and control policy, the control requirements for different risk categories are different:
1. Confirmed cases or asymptomatic infected persons: sent to the designated hospital for isolation and treatment of new crown pneumonia.
2. Close contact (close contact of confirmed cases or asymptomatic infected persons): sent to the designated place for centralized isolation for 14 days
3. Sub-close connection (close connection): Sent to the designated place for centralized isolation for 14 days
4. High screening (high-risk screening object): 2 days of home isolation (not allowed to leave the residence) + 12 days of community health observation (can travel normally, avoid crowd gathering)
It is because of such an action as taking off the mask, but it takes 14 more days of centralized isolation!
In fact, most people still have the awareness of wearing masks, and the protection habits are better, but they are always lost in the details.
For example, two customers have masks in the store, go out for a walk after ordering, and then come back to get milk tea, and the mask magically "disappears"! Some people suddenly pulled down their masks after getting milk tea, plugged in straws and drank two sips directly...
The masks worn by many takeaway brothers are not very standardized. Some takeaway brother masks are hung on the chin, and the nostrils are exposed, which does not play any protective role.
Of course, close contact judgment is a technical job, not only to see whether a mask is worn, but also depends on the distance with the positive person, the time of communication, etc. Every time one more close connection is determined, there will be N more close connections, and a bunch of risk control groups, and for the epidemic prevention department, the workload is increased exponentially.
Therefore, wearing a mask is not a coping, and not wearing it is equivalent to not wearing it. In the mall ordering, shopping, etc. should be standardized to wear a mask, absolutely do not have any luck.
Beijing announces traceability results!
These points should be reminded again
On January 17, at the 267th press conference on the prevention and control of the new coronavirus pneumonia epidemic in Beijing, Pang Xinghuo, deputy director of the Municipal Center for Disease Control and Prevention and a member of the national new coronavirus pneumonia expert group, briefed on the traceability of the confirmed cases of new coronavirus pneumonia in Haidian District of the city.
The case reported having recently received international mail. We conducted a thorough investigation, sampling and testing. The international mail was sent from Canada on 7 January, via the United States and Hong Kong, China, to Beijing, and the case received the mail on 11 January. The case is self-reported, during which time it only touched the outer surface of the mail package and the first page of the document paper, and did not touch the inner surface of the package and other papers. 22 environmental specimens of the international mail have been collected, including 2 on the outer surface of the package, 2 on the inner surface and 8 specimens on paper in the document, all of which were positive for nucleic acid testing, and the specific mutation sites of the Omikerong strain were detected.
Pang Xinghuo introduced that there was no history of travel in other provinces and cities in the 14 days before the onset of the case, and international mail was occasionally sent and received during the work. The case developed itchy throat symptoms on January 13, fatigue and fever on January 14, no typical manifestations of new coronary pneumonia in lung CT on January 15, and the change in the nucleic acid detection CT value of the case specimens on January 14, 15 and 16, combined with clinical manifestations and test results, it was preliminarily judged that the case was in the early stage of infection.
It is recommended to minimize the purchase of overseas goods, and pay attention to receiving overseas mail!
In the past, many provinces (cities) on the mainland have also reported cases of transmission through cold chain or non-cold chain items, and recently many places in the mainland have also reported positive overseas mail and other items. The coronavirus can survive in low temperatures for a long time, and the risk of material transmission in winter increases.
At present, the new crown pneumonia epidemic caused by the global Aomi Kerong variant strain is high, and the general public is reminded of the general public:
First, during the high incidence of the epidemic in foreign countries, minimize the purchase of overseas goods.
Second, if you receive mail or items from abroad, you should wear masks and disposable gloves correctly to reduce direct contact and communication.
The third is to pick up the package at a fixed location as much as possible to achieve contactless handover; if you need to sign in person, please keep a safe distance from the courier.
Fourth, when disassembling parts, try to carry out outdoors, the outer packaging should not be taken home, and should be sorted according to the classification of domestic garbage; if it needs to be taken home, the internal and external packaging can be fully disinfected with chlorine disinfectant or 75% alcohol.
Fifth, after handling the mail, take off the gloves in time, carefully disinfect or wash the hands, replace the mask, and avoid touching the mouth, eyes, and nose with unclean hands.
