nucleic acid detection is a key means to quickly discover the source of infection. Why do multiple rounds of nucleic acid testing need to be conducted? What are the precautions for large-scale nucleic acid testing? How to ensure the accuracy of nucleic acid test results? On September 21, in response to the issues related to nucleic acid testing that everyone is concerned about, the reporter interviewed Gong Rui, head of the Infectious Disease Prevention and Control Section of Ningxia Center for Disease Prevention and Control.
Why do we need to carry out multiple rounds of nucleic acid testing? Gong Rui said that as the current epidemic prevention and control enters the stage of responding to the epidemic of Omickron mutant strain, the Omickron mutant strain has the characteristics of faster transmission, shorter incubation period and stronger concealment. We must use fast control and fast, and promptly and effectively cut off the virus transmission chain in order to achieve the maximum prevention and control effect with the minimum cost.
In the event of an epidemic, through short-term and multiple rounds of nucleic acid testing, and as soon as possible, "all tests should be tested" and "all close contacts should be transferred" can be detected in a timely manner by detecting new coronavirus infected people in the society, detecting and controlling the source of infection in a timely manner, and blocking the spread of the epidemic. It is also possible to judge the epidemic prevention and control risks based on the number of infected people detected and their distribution, and decide whether to expand the scope of nucleic acid testing and the frequency of testing. We call on everyone to undergo nucleic acid testing as soon as possible in accordance with the requirements of the autonomous region.
What should be paid attention to when conducting large-scale nucleic acid testing? Gong Rui introduced that when organizing nucleic acid testing, all parts of Ningxia have made good work plans and organizational management, straightened out the entire chain work process, coordinated and coordinated by multiple departments, and established a flat working mechanism. At the same time, in terms of the setting and layout of the sampling points, the population size, geographical traffic, distribution of nucleic acid testing institutions will be determined in detail. Especially in this season, outdoor sampling points are given priority, as well as organizational units, schools, etc. to conduct centralized collection. Clear guidance signs were set up at the collection site to plan the entry and exit routes to ensure one-way flow of personnel. By making appointments, notifications and sampling in advance, people gathering in a short time and shorten the queue time. Staff and volunteers were equipped on site to strengthen order maintenance, guide the masses to take personal protection, maintain a safe distance, and avoid cross-infection. A green channel has been set up for the elderly, pregnant women, and disabled groups.
"We strive to ensure the safety and smoothness of large-scale nucleic acid testing." Gong Rui said that he also reminded the general public to implement measures such as wearing masks and maintaining safe distance, and consciously obey the organizational management of staff. During the sampling process, do not touch any objects such as the sampling table and leave as soon as possible after the sampling is completed to reduce on-site stays and conversations.
So how to ensure the accuracy of nucleic acid test results? Gong Rui introduced that Ningxia has timely formulated and improved corresponding technical specifications in accordance with national requirements to ensure the standardization of the entire inspection process. Continue to carry out training for nucleic acid testing personnel to minimize the accuracy of nucleic acid testing results due to human factors. At the same time, indoor quality control and inter-room quality evaluation are strengthened, and all laboratories are required to do a good job in indoor quality control. In addition, a working system for quality control supervisors to participate in quality supervision has been established. During the work of nucleic acid testing for all employees, it is required that the institutions responsible for nucleic acid testing should be dispatched to conduct 24-hour quality control for institutions responsible for nucleic acid testing to ensure the quality and accuracy of large-scale nucleic acid testing for all employees.
