Large-scale nucleic acid detection does not give the virus a chance to "hidden growth"
■ Editorial
Beijing has further expanded the scope of regional screening in order to identify all potential infected persons as soon as possible and prevent the large-scale spread of the epidemic.
On the evening of April 25, at the 315th press conference on the prevention and control of the novel coronavirus pneumonia in Beijing, Xu Hejian, deputy director of the Propaganda Department of the Beijing Municipal Party Committee, director of the Municipal Government Information Office, and spokesman of the municipal government, announced that Beijing will hold an event in Chaoyang. On the basis of the nucleic acid testing that has been carried out in the district, the scope of regional screening will be further expanded. From the 26th to the 30th, three rounds of nucleic acid testing will be carried out for personnel in 11 districts in Beijing.
On the afternoon of April 26, Pang Xinghuo, deputy director of the Beijing Center for Disease Control and Prevention, introduced that since April 22, Beijing has reported a total of 92 cases of new coronary pneumonia virus infection, involving 8 districts.
At present, there are 2 high-risk areas and 12 medium-risk areas in the city.
Based on the current risk research and judgment, relevant departments divide risk areas, closed control areas, and control areas in a timely manner, and implement classified management, which is a necessary measure for early detection and control of new coronavirus infections, blocking the transmission of the epidemic, and effectively curbing the spread and spread of the epidemic in the community. .
At this time, it was decided to further expand the scope of regional screening and conduct multiple rounds of nucleic acid testing for all staff in a short period of time, in order to identify potential infected persons as soon as possible, cut off the chain of epidemic transmission, and prevent the large-scale spread of the epidemic.
This round of epidemic situation in Beijing is fierce, and Omicron's super infectiousness has brought many difficulties to epidemic prevention and control.
According to Liang Wannian, head of the expert group of the National Health and Medical Commission's New Crown Epidemic Response Leading Group, one Omicron infected person can infect 9.5 people without intervention.
Fortunately, from the current point of view, Beijing's epidemic transmission chain has been properly managed and controlled, prevention and control measures have been followed up, and new cases have been managed and controlled in a timely and effective manner.
As a mega-city, Beijing has a high population density and high mobility, and objectively, the risk of hidden spread of the virus is greater, which increases the difficulty of epidemic prevention and control.
Therefore, if we want to outperform the transmission speed of Omikron, we need to take faster measures to cut off the transmission chain, which requires us to adhere to "dynamic clearing", in-depth investigation, and quick screening and strict management. Relax.
In the critical period of epidemic prevention and control, timely and large-scale nucleic acid testing of all staff is the sentinel to discover "enemy situation", and its necessity and importance are self-evident.
According to the previous prevention and control experience and the virus characteristics of Omicron, it usually takes two to three rounds of nucleic acid testing to identify potential infected persons as much as possible.
It can be said that the current large-scale nucleic acid testing of all employees is still the most effective means of prevention and control in the "quick and fast" approach.
In fact, only by "cleaning up" the virus and not giving the virus a chance to "hidden growth" can we avoid the risk of transmission and cause greater losses.
Currently, except Mentougou, Pinggu, Miyun, Huairou, and Yanqing districts, other areas in Beijing are carrying out nucleic acid testing for all employees, covering 90% of the total population in Beijing.
Large-scale nucleic acid testing is not only a very professional work, but also involves a wide range of social mobilization and organizational management.
Due to the large scale of screening and the large number of people, relevant departments should build as many detection and sampling points as possible, strengthen guidance and prompts, avoid crowds gathering and contact, and reduce the risk of virus transmission.
Therefore, the street community may wish to take measures to take samples at different times and in batches to reduce the waiting time of residents as much as possible, improve the efficiency of testing, and allow "office workers" to go to work after finishing nucleic acid.
At the same time, qualified communities can provide green channels or door-to-door sampling services for special groups such as the elderly and the disabled, providing maximum convenience for residents to detect nucleic acids.
The completion of large-scale nucleic acid testing with high quality and efficiency within the specified time still depends on the collaborative work of community staff, medical staff, and volunteers, as well as the active cooperation of residents, striving to control the epidemic for Beijing as soon as possible and realize social dynamics Clear up and contribute your own strength.
