Original title: How to prevent and control 8 local cases in Shanghai in 13 days
Since a new local confirmed case was added on November 9 (Wang Moumou, a porter at the Pudong Western District Airport Cargo Terminal), Shanghai has so far discovered 8 confirmed cases of new coronary pneumonia associated with the Pudong Airport. Pudong. The place of residence of the relevant cases is classified as a medium risk area. Among them, Wang’s place of residence and Yingqian Village, Pudong New Area have not confirmed new local cases for 14 consecutive days, and it will become a low-risk area from 0:00 on the 24th.
This morning, the 88th press conference of Shanghai coronavirus epidemic prevention and control work became the center of attention in Shanghai and even across the country. At the meeting, the authorized department asked relevant questions about “how the first local case got infected”, “what specific prevention and control measures has the Pudong International Airport taken”, “how the Pudong airport organized the nucleic acid tests for all the employees in the cargo area last night. ” Reply.
The first “puzzle” was solved and the North American aviation container became infected without wearing a mask.
How did Wang Moumou get infected? During the cleanup, neither Wang nor Lan, who later returned to Anhui, reportedly did not wear a mask, which is the main cause of infection.
Sun Xiaodong, deputy director of the Shanghai Centers for Disease Control and Prevention, introduced that after Wang Moumou was diagnosed, the Shanghai Department of Disease Prevention and Control verified 28 close contacts, 190 close contacts of close contacts, 51 general contacts and 9,617 related people. 1428 environmental samples were obtained, all negative. It is worth noting that on November 10, the day after Wang’s diagnosis, a case of Lan from Pudong Airport appeared in Anhui. The Shanghai disease control department brought these two cases together for traceability investigation.
The results showed that none of them had had contact with relevant cases, nor had they contacted immigration personnel or crew members in the 14 days prior to the onset of the disease. Consequently, the disease control department ruled out the possibility of “person-to-person transmission.” Additionally, the two had no contact with imported cold chain food and related links within 14 days.
However, the disease control department found that on October 30, Wang and Lan entered the airport cargo area together and cleared an aviation container from North America. This is a closed container with moisture inside. Neither man wore masks when cleaning the container. Furthermore, after genetic sequencing, the genes of the diseased strains infected by the two are very similar to those of the North American epidemic.
“Therefore, we believe that the source of infection is imported from abroad,” Sun Xiaodong said.
Pudong Airport performed nucleic acid tests on cargo personnel overnight and 1 person tested positive
From November 20 to November 23, the staff of the Pudong airport cargo terminal Wu Mo and his wife, Wu Mo’s colleague Wang Mo and his wife, Wu Mo’s colleague Cao Mo, and FedEx employee from Zhang Mo Airport Diagnosed one after another. This morning, Zhou Junlong, Vice President of Shanghai Airport Group, presented at a press conference that Pudong Airport organized an overnight force to conduct nucleic acid tests on personnel in the airport cargo unit. The reporter was informed that at 9:30 p.m. today a total of 17,719 people had been sampled, one person was positive and the rest were negative.
Zhou Junlong introduced that the current status of the confirmed persons shows that they are all related to the cargo area of the airport and not the passenger transportation area, including the terminal.
The reporter learned that Terminal T2 at Pudong Airport is currently operating normally. This morning there were very few cancellations of domestic, international and regional flights, and passengers entered and left the port as usual. Currently, interprovincial passenger transport in Shanghai also works as usual.
Earlier, Zhang Wenhong, leader of the Shanghai medical treatment expert team, said that with the arrival of winter, the global epidemic will spread and increase the risk of epidemic prevention and control, especially for logistics-related personnel. In this context, he believes that “there are sporadic cases in China.” .
All parties cooperate, the epidemic is under control.
Faced with the risk of the epidemic, what work has Shanghai done in recent days?
Li Guohua, deputy director of the Pudong New Area, said that the new area has a set of plans and action plans for the release of suspected cases, confirmed cases and medium-risk areas in accordance with the epidemic prevention and control requirements. . After receiving the news of the suspected cases, the new district will accurately capture the flow of suspected cases, the relationship between relatives and the situation in the area where they live, and will organize a sufficient number of sampling personnel, security assurance personnel prevention and control, service personnel, etc. according to plan. . Once the medium risk area is released, closed management will be implemented immediately, nucleic acid testing of all employees will be performed in a prompt and orderly manner, and terminal disinfection will be implemented. Strictly implement the 14-day health management and community management requirements, inform residents to take their body temperature twice a day, and strictly implement the “zero report” system for fever detection.
Xu Jin, deputy director of the Shanghai Municipal Market Supervision Office, introduced that recently, the market supervision department, together with the health department, has conducted sampling and testing of imported cold chain food in key places such as large farmers markets, supermarkets and cold rooms. As of November 22, Shanghai has dispatched 180,000 police personnel to inspect more than 177,000 commercial food units; A total of 130,000 samples were analyzed and the results of the nucleic acid tests for the new coronavirus were all negative.
Shanghai initiated the “transit inspection warehouse” policy at 0:00 on November 16, for imported high-risk cold chain foods entering customs in Shanghai port and stored, processed and sold in Shanghai, except those that have been inspected and cleared by customs. In addition to direct release, it must be uniformly entered into the corporate transit inspection library or public transit inspection library for nucleic acid testing and outer packaging sterilization, and release can only be done after the result the test is negative. Xu Jin said that Shanghai is carrying out “full chain control” of these imported cold chain foods.
On the night of November 22, Zhang Wenhong posted an article on Weibo explaining the “new anti-epidemic trend after multiple local cases in winter.” He said that from the perspective of prevention and control effects, the current epidemic is under control and there are no continuous second-generation cases in the community. He recalled that the long-term and arduous nature of future epidemic prevention challenges may exceed most people’s imaginations.
It is worth noting that in the past two days, experts from all walks of life in Shanghai have repeatedly reminded the public to “wear a mask.” Wu Jinglei, director of the Shanghai Municipal Health Commission, specifically noted that the five local cases in Shanghai that began on November 20 have more or less symptoms such as hyposmia, taste and diarrhea.
