(Express for the two sessions) Huang Ailong, member of the National Committee of the Chinese People's Political Consultative Conference: Epidemic prevention and control should embark on "home self-test" as soon as possible
China News Service, Beijing, March 8 (Peng Guowei Huang Weizheng) "Since the outbreak of the new crown pneumonia, various methods such as virus nucleic acid detection, antibody detection and antigen detection have been widely used, which has curbed the spread of the virus to a certain extent." Member of the National Committee of the Chinese People's Political Consultative Conference . Huang Ailong, President of Chongqing Medical University, suggested during the National Two Sessions in 2022 that on this basis, the normal state of "large-scale rapid antigen detection based on home self-test + targeted small-scale accurate nucleic acid detection" should be established as soon as possible. Change the mode of epidemic prevention and control.
Huang Ailong's investigation found that currently nucleic acid testing can only be carried out in professional institutions such as laboratories or hospitals, requiring professionals to operate, and it usually takes about a few hours to obtain results. Nucleic acid testing is expensive, time-consuming, and slow to produce results.
When a confirmed patient needs to be screened for nucleic acid testing in a place, large-scale queues are organized for testing, and there is a risk of people gathering and cross-infection.
Huang Ailong suggested that it is necessary to give full play to the respective characteristics of the existing nucleic acid and antigen detection technologies and the advantages of applying big data technology.
"Compared with nucleic acid detection and antibody detection, antigen rapid detection has many advantages such as simple operation, fast efficiency, wide application, low cost, safety and reliability, and can greatly reduce the burden on medical staff and medical and health institutions." Huang Ailong introduced that antigen rapid detection It takes less than 30 minutes to obtain the results of the test, and the cost of reagents is about 20% of that of nucleic acid testing. If the organization is strong, the screening of large-scale people can be completed in a short period of time in various conferences, sports events and other large-scale activities.
"Since 2021, some parts of the country have carried out 'home self-test' emergency drills for large-scale rapid antigen detection." Huang Ailong introduced that taking Chongqing as an example, Chongqing Medical University has conducted drills with Bishan District and High-tech Zone in Chongqing. The organization and implementation mode includes steps such as "establishing a working group - publicity notice - personnel training - reagent distribution - self-testing - background result confirmation - test result management".
At the same time, through the cooperation with the Chongqing Big Data Application Development Administration, the self-developed new coronavirus antigen detection artificial intelligence identification WeChat applet also provides new support for large-scale rapid screening of the new coronavirus.
During the emergency drill, a total of 16,000 antigen rapid detection reagents were distributed, and valid data was collected for 15,022 people, with a completion rate of 75.11% in 8 hours; 15,017 people were identified as negative by the self-developed artificial intelligence system, and the consistency of the review with professional technicians is 99.97%.
Huang Ailong said that through the exercise, it was further verified that the use of rapid antigen detection for large-scale early screening has many advantages, which can be widely promoted.
Huang Ailong told reporters that promoting the construction of a normalized epidemic prevention and control model that combines "large-scale rapid antigen testing based on home self-testing + targeted small-scale accurate nucleic acid testing" can not only complete large-scale epidemics in a very short time The initial screening of the population, as soon as possible to grasp the general scope and activity trajectory of the early infected people, close contact with the population, can further determine the infected people and the spread of the virus.
"The combination of the two can greatly improve the efficiency of epidemic prevention and control, and can also greatly reduce the cost of epidemic prevention and control, and reduce the restrictions and impacts on economic development caused by epidemic prevention and control." Huang Ailong said.
