At 8:00 a.m. on August 14, Fan Wen went into the horse box store as usual and planned to buy breakfast before going to work. However, he suddenly found that there were a group of medical staff in white protective clothing and fully armed. < / P > < p > “Xiao Fan, go and do the nucleic acid test quickly!” He was suddenly stopped by his colleagues, but did not know what happened to Fan Wen, but not in a hurry, “I want to buy a breakfast.” He said. In the vicinity of IBC shopping mall in Shuibei District, the district government and various administrative departments often have routine inspection. Therefore, most HEMA employees feel very normal, and the HEMA shellfish shop has also conducted a large-scale monitoring before. < / P > < p > “what kind of breakfast to buy and go quickly.” The reaction of his colleagues made him aware of the seriousness of the situation. At this time, the news of the diagnosis by the staff of the hippo store has not been spread. However, with the nucleic acid detection going on, Xiao Fan received a notice that the business of the HEMA shellfish shop needed to be suspended, and all the staff of the Shuibei shop had to be isolated in a centralized way. He realized that something had happened. < / P > < p > “slowly, we all know that there is a diagnosis. In the morning, they said that maybe the salesman was suspected, and later they knew it was confirmed.” Fan Wen recalled the interface news. < p > < p > after receiving the notice of closure, Fan Wen quickly made a notice and posted it at the door of the store. Some customers in his wechat community began to ask, why can’t we place orders? By noon, the nucleic acid detection of the staff of the shell shop was basically completed, but still needed to contact the personnel on leave or in the field. Xiao fan can only call them one by one, and must immediately go to do nucleic acid testing, and then report to the community. < / P > < p > many sales promotion aunts move very fast. Some of them only appear on weekends or on Fridays, Saturdays and Sundays. Even HEMA employees can’t get to know them all. However, it is necessary to contact these aunts for nucleic acid detection. The employee diagnosed by HEMA before is a salesman of a certain brand. < p > < p > the nucleic acid detection of HEMA Shuibei shop was basically completed on the afternoon of the 14th, and the employees were respectively called on the buses to the isolation hotel. The doctor assigned a room for each person and gave each person a bag containing two buckets of instant noodles and a eight treasure porridge. < / P > < p > “in terms of mentality, most people are quite OK, but when she has a younger sister, she cries. As soon as she hears that she needs to be isolated, and then at least 14 days later, she is in a bad mood.” Fan Wen said. < p > < p > due to the community operation of HEMA, Fan Wen got to know many old customers nearby. Some people sent messages to inquire about his condition, and customers called to inquire about his isolation environment and food. His mood began to relax. < p > < p > Li Huabin, the security officer of HEMA, arrived at the scene at 5:00 p.m. on August 14. HEMA and its IBC building have been taken over by the government and completely blocked. Only those who have carried out nucleic acid testing can come out. He and other management personnel who went to the scene at the same time could only wait outside the field, watching the medical staff in protective clothing shuttle around the field. < p > < p > checking the list of employees, waiting for the results of nucleic acid testing, and cooperating with the government to resettle all employees of the HEMA Shuibei store to the isolation point, Li Huabin’s work lasted until 4:00 a.m. the next day. < / P > < p > he was also scared. “I didn’t think too much about it when I went there, but after the resettlement work on that day was over, I thought, I couldn’t go home, I was here all day.” Worried that he might carry the virus, Li Huabin immediately did a nucleic acid test. Although his results were negative, he stayed out for two nights before he dared to go home. < / P > < p > after the evacuation of the epidemic prevention medical staff, the Shema Shuibei shop still could not be quiet. This 5000 square meter site has a large number of goods to be counted and processed. Zhang Zefeng was the first batch of staff to go to the scene to check the goods. On the afternoon of August 15, personnel waiting for nucleic acid detection at shuibeidian test site in HEMA, Shenzhen, surrounded the whole building. The serpentine queue extended from the detection point to 800 meters to the left of the mall. Seeing this kind of scene, Zhang Zefeng could not help but feel a little nervous. < p > < p > but the work was more arduous than he had imagined. There are nearly 5000 SKUs and nearly 20000 commodities in HEMA Shuibei store, including aquatic products and chilled fresh products that are difficult to handle. Zhang Zefeng and the other four people need to pack the sampled and tested products as soon as possible, so as to prepare for subsequent disposal such as destruction. The intense physical labor lasted from 2:00 p.m. to 11:30 p.m., and continued throughout the morning the next day. To make matters worse, the entire building where the HEMA Shuibei shop is located has been cut off for a long time due to the blockade. Without air conditioning, it was extremely hot in August in Shenzhen. Employees had to work in the dark, and their protective clothing was soaked with sweat. Due to the inconvenience of wearing and taking off the protective clothing, they could only go to the toilet every two hours under the leadership of the epidemic prevention staff. < p > < p > the investigation of the Shema Shuibei store and the IBC building is just the beginning of the epidemic tracing. At 1:00 a.m. on August 15, all employees of HEMA Xiansheng in Shenzhen were bombed by telephone. They were told in their sleep that from that day on, 21 HEMA stores in Shenzhen would be closed for nucleic acid testing. Many employees were immediately recalled and began to return online orders. < / P > < p > the products of HEMA Shenzhen store have also ushered in a big clearance point – fresh products have to be reported damaged and destroyed, and all imported frozen products have been returned to the warehouse and their sales are suspended. Nowadays, most of the Shenzhen HEMA stores are very empty. However, due to the negative results of all nucleic acid tests, their isolation life was relaxed. It’s even a little boring. Some people began to practice writing brush, some in the room fitness, some people also began to plant flowers. Familiar old customers are happy to chat with them and exchange their nucleic acid test results from time to time. August 14 was like a nightmare. In fact, according to the Shenzhen Health Commission, as of 8:00 on August 20, a total of 617700 personnel samples (including all employees of 21 supermarkets and 2 warehouses of HEMA Xiansheng in the city) had been collected, and 590200 samples had been tested. Except for two asymptomatic infections found on August 14 and a new asymptomatic infection among the isolated close contacts on August 19, the other test results are negative. As of 24:00 on August 19, 1197 food samples and 1779 environmental samples had been collected by the disease control department of the whole city. At present, the nucleic acid test results were negative. According to the Shenzhen Health Commission, according to the current report of asymptomatic infected persons and nucleic acid screening, the “8.14” epidemic in Shenzhen was quickly detected, prevented and controlled in time, and the risk of spread and spread has been effectively controlled. < / P > < p > the results of this epidemic risk investigation show that the risk of a large-scale epidemic rebound in the city is extremely low. Of course, low risk is not equal to zero risk. At present, Shenzhen is in an important stage of actively preparing for the epidemic prevention and control in autumn and winter.
