  More than 12 million people were sampled in 6 hours, and nucleic acid tests for more than 10 million people were completed in 24 hours... Since the rebound of the epidemic on January 3, Zhengzhou has raced against time to quickly complete multiple rounds of nucleic acid testing.

  In the early morning of January 4, Zhengzhou New Coronary Pneumonia Epidemic Prevention and Control Headquarters issued the first notice in 2022. Zhengzhou City found 2 cases of asymptomatic infection of new coronary pneumonia in the routine nucleic acid test on January 3.

Subsequently, the number of confirmed cases continued to increase, with 7, 33, and 57 cases. As of January 11, a total of 115 local cases have been confirmed in Zhengzhou in this round of epidemic.

  The epidemic has rebounded again. Zhengzhou, which has experienced two epidemic "big exams" in the past six months, raced against time to carry out prevention and control work such as isolation and quarantine, flow investigation and investigation, and centralized treatment.

Zhang Ruoshi, deputy director of the Henan Provincial Health and Health Commission, introduced that after gene sequencing analysis and comparison, the Zhengzhou epidemic and the Xuchang Yuzhou (county-level city) epidemic virus gene sequence had high homology, and the virus gene sequencing was the delta strain.

However, the source of the virus is still unclear, and the prevention and control situation is severe and complicated.

  "When the risk of infection and spread is unknown, continuous multiple rounds of nucleic acid testing have become a must for quickly discovering potential infections and quickly locking down risk areas." said Lv Tinglin, director of the Organization Department of the Zhengzhou Municipal Party Committee. Testing tests a city's mobilization ability, sampling ability, and testing ability.

  To this end, Zhengzhou relies on the organization department to set up a nucleic acid testing headquarters, and set up 9 special groups including sampling, transfer, testing, quality control, and information, and 55 professionals responsible for nucleic acid testing in Zhengzhou's epidemic prevention and control in August and November last year. Arrival scheduling.

  This is a "battle" where every second counts and there is no gunpowder.

Zhengzhou has invested more than 33,000 sampling personnel, set up 6,398 sampling points, invested more than 2,000 vehicles and more than 4,000 transfer personnel to quickly transport specimens point-to-point, and nearly 10,000 information personnel are responsible for information reporting.

With the support of field testing personnel and equipment, Zhengzhou has formed a daily nucleic acid testing capacity of up to 1.8 million tubes.

More than 100,000 community workers, volunteers, and police officers are on the front line of epidemic prevention. "Angel White", "Volunteer Red" and "Guardian Blue" can be seen everywhere in Zhengzhou's streets and alleys.

  In the face of the epidemic, there are no bystanders, let alone outsiders.

On January 4, heavy snow fell in Zhengzhou.

Thick snow fell on the stool behind him, and Yang Xinyuan, a nurse at Zhengzhou Central Hospital Affiliated to Zhengzhou University, had been standing for a long time.

Yang Xinyuan said: "I don't care about sitting, I just want everyone to wait a little less in the wind and snow, hurry up, hurry up!" Zhang Jie, who has been a volunteer for many times of epidemic prevention, held a small speaker to remind residents to stay one meter apart. Line up in an orderly manner, Zhang Jie said: "Zhengzhou has a population of 10 million, time is tight, and testing volume is large. Do your best to fight the epidemic. Everyone is inseparable."

  From January 3 to 11, Zhengzhou, with a population of more than 12 million, completed four rounds of nucleic acid testing for all employees and six rounds of nucleic acid testing for key populations.

During the critical window period of epidemic prevention, from January 7 to 9, Zhengzhou completed one round of nucleic acid testing for over 10 million people every 24 hours, and three rounds of nucleic acid testing for all employees in three days. The peak value of nucleic acid sampling information entered was 2.633 million people per hour. .

  Guo Yonghao, director of the laboratory of the Immunization Planning Institute of the Henan Provincial Center for Disease Control and Prevention, said that because the new coronavirus has a certain incubation period and concealment, some infected people cannot be detected in time during nucleic acid testing.

Therefore, in order to detect infected persons as soon as possible and cut off the chain of virus transmission, multiple rounds of nucleic acid testing should be carried out in time.

  At present, Zhengzhou has completed more than 62 million nucleic acid tests.

Wang Baolai, Deputy Secretary-General of the Zhengzhou Municipal People's Government, introduced at a press conference on the 11th that in the nucleic acid screening of all staff, except for the closed and controlled areas, Zhengzhou's society has reported zero positive cases for three consecutive times.

  On January 12, residents in the main urban area of ​​Zhengzhou, who had conducted six consecutive rounds of nucleic acid testing for all employees, were notified. Except for residents in key areas such as closed control areas and control areas, as well as key personnel such as taxi drivers and online car-hailing drivers, non-key Regional personnel and residents of the prevention and control area can suspend nucleic acid testing.
