Original title: How to basically complete nucleic acid tests for all employees in cities with tens of millions of people in 5 days? ——Nucleic acid testing observation for all Qingdao employees
Xinhua News Agency reporters Zhang Xudong, Yang Wen, Yan Xiangling
4 new confirmed cases of new coronary pneumonia and 5 asymptomatic infections … On October 12, the epidemic in Qingdao caused great concern.
As a city with a population of tens of millions, Qingdao has decisively initiated nucleic acid testing for all employees and resolutely advocated for the hard-won national epidemic prevention and control results. As of 8 o’clock on the 15th, Qingdao City has completed more than 9.94 million nucleic acid analysis samples, with more than 7.64 million results and no new positive samples. How can a large-scale nucleic acid test be completed in just 5 days?
Sister cities fight “pandemic” with Qingdao
“163 inspection points in Shinan district, inspection from 5: 30-23: 00” “130 inspection points in Shibei district, all in these places” … Since the 12th, the various districts and cities of Qingdao have successively announced and continuously updated inspection points in their jurisdiction and detection time. Some public WeChat accounts have released warm reminders such as “Dear, have you completed the nucleic acid test?” And started a broad community mobilization.
In Baiguoshan Tourism Service Center Plaza, Bijia Upper Community, Shiyuan Street, Licang District, Qingdao City, more than 100 residents lined up in front of the tent at the inspection point, 10 people completed one form and 10 people were admitted to each lot; At the Qingdao University Medical College Stadium, students line up in a semi-arc team around the track and field.
“Children, open your mouth, do not be afraid.” At the Shui’an Mansion Community Inspection Point, Sanlihe Street, Jiaozhou City, Qingdao, a 42-year-old medical worker, Su Miao, was squatting to collect a throat swab for a child. She said, “Children are more scared, so they need to be comforted as they focus on taking accurate samples and strive for success.”
In order to ensure completion of nucleic acid testing for all employees within 5 days, and to perform early detection and removal, many test sites operate from early morning to late night. On the 12th, Su Miao was busy from 2:00 p.m. to 11:00 p.m. “They are relatively hot and congested with their protective clothing, and all the sweat runs down the soles of their feet,” said Yuan Ping, the person in charge of the inspection point.
Nucleic acid testing of all employees in Qingdao, rapid cooperation with counterparts——
According to Chen Wansheng, deputy director of the General Office of the Qingdao Municipal Government, Shandong Province has coordinated arrangements for five prefectures in Zibo, Yantai, Weifang, Weihai and Rizhao to carry out counterpart collaborations with five districts in Qingdao to receive samples. nucleic acid for testing; 7 additional branches and 210 people will be sent Nucleic acid test team brought 28 sets of nucleic acid test kits and 56,000 reagents to support Qingdao; A nucleic acid sampling team of more than 1,000 people from other cities in Shandong province was organized to support sample collection.
In the east-west poverty alleviation cooperation, Chengxian County, Longnan City, Gansu Province, which is the counterpart of Chengyang District, Qingdao City, sent a medical team consisting of 50 medical staff to support him on the 13th. Two hours after arriving in Qingdao, he underwent community nucleic acid testing and sampling.
With the help of foreign support personnel and local medical personnel, there are tens of thousands of medical personnel carrying out nucleic acid testing and sampling in Qingdao.
From “people to people” to “subway line”
When nucleic acid testing was first started, there was a crowding phenomenon at some test points. In this regard, Qingdao has further enriched its testing capabilities, scientifically organized test points, and strengthened on-site order maintenance.
With the addition of test power, test sites continue to increase and there are currently more than 4,000 fixed test sites in the city. Some checkpoints placed a one meter line on the ground to allow residents to line up at regular intervals. During this period, more than 20,000 volunteers organized in 5 districts of the main urban area of Qingdao to carry out information registration and order maintenance at the sampling site. Volunteers are mainly made up of police officers, government officials, and spontaneous people.
On the night of the 13th, in Fulinyuan Community, Fushan Road, Licang District, Qingdao City, due to limited high light conditions in the square, a retired Zheng Song soldier took a flashlight to illuminate the registered personnel during almost 6 hours. “When suddenly launching a nucleic acid test for all employees, there must be a lot of unexpected difficulties, but it is not difficult for everyone to come together,” he said.
It usually takes less than a minute to sit up, remove the mask, and open your mouth to collect the throat swab. The process that takes the most time is the information registration process. In order to improve efficiency, Yunnan Road Community, Shinan District, etc. They switched the manual registration of citizens’ information to QR code scanning, which greatly reduced the waiting time.
At 24:00 on the 14th, nucleic acid tests were basically completed for all employees in the 5 districts of Qingdao City, including Shinan and Shibei, and all results were negative. This marks the completion of the nucleic acid test for all employees in the main urban area.
For some residents with limited mobility and unable to reach the collection point, Qingdao has specially arranged on-site sampling services. A group of inspectors quickly moved from fixed inspection sites to mobile inspection sites. Du Xiaoxuan, a member of the medical staff who came to Zibo’s support, was one of them. “My father is 81 years old and his actions are very difficult. Sampling the house is really helpful,” said the son of an elder Lin Zhenmao of Liaoyuan Road Street, Shibei District, Qingdao.
Technology enables large-scale nucleic acid detection
Qingdao City adopted “10 in 1 mixed collection detection technology” in this nucleic acid test for all staff, which means that samples from 10 people are mixed and analyzed only once. “If a 10 in 1 sample is positive, we will immediately notify these 10 people to be isolated immediately and we will perform a one-time collection and one-time controls on these 10 people to determine the carriers of the positive sample. Qingdao City Diseases, said Zhang Huaqiang, deputy director of the control center.
According to reports, “10-in-1 mixed mining detection technology” was urgently developed in the real fight against the epidemic in Dalian, greatly improving the detection efficiency. You can examine more non-key areas and diagnose early in the emergency response, and restore order of production and life as soon as possible. Plays an important role.
While improving collection efficiency, Qingdao strives to improve sample detection capabilities and efficiency. On the 14th, Qingdao Huada’s “Huoyan” laboratory was upgraded and expanded. It added 27 automated nucleic acid extractors and 61 core nucleic acid detection kits. The design’s daily detection throughput increased from 2,000 individual tubes per day to 40,000 individual tubes per day. , Performance increases 20 times.
As the core force of Qingdao Internet industrial platform, Haier Kaos quickly matched the material requirements with the epidemic prevention material assurance teams of various districts and cities, and quickly solved the shortage problems of 100,000 sets of tubes of virus sampling and throat swabs in an urban area.
