What information is worth paying attention to in the announcement of global nucleic acid antigen detection in Gui 'an, Guiyang on September 7?

The announcement that Gui 'an, Guiyang launched the global nucleic acid antigen test on September 7th, in which the noteworthy information is: Gui 'an, Guizhou launched the nucleic acid antigen test this time, using portable rapid nucleic acid detection reagent instruments, residents can detect whether there is COVID-19 at home, reducing crowd gathering and the risk of COVID-19 spreading everywhere. Among them, the noteworthy information is that Gui 'an, Guizhou Province attaches great importance to this nucleic acid detection, and the low-risk area adopts a mixed detection method of 20 people, and the medium-risk area adopts a household detection method. This measure is also to improve the speed of nucleic acid detection, increase the accuracy of nucleic acid detection results, and screen out high-risk groups in the population, which is still worth popularizing throughout the country.

The COVID-19 epidemic in Gui 'an, Guizhou Province has been going on for some time. Because of the fear of mixing a positive patient in the process of gathering residents for nucleic acid testing, it will cause a large-scale transmission event. Therefore, Guizhou Gui 'an carried out self-test at home and popularized nucleic acid antigen detection. Convenient and fast nucleic acid detection instruments will be distributed to every family and everyone by professional staff. Never leave a person behind, as long as residents follow the collection method on the video, they can correctly extract samples. This kind of nucleic acid detection does not need to be sent to a professional place for inspection. Residents can identify positive patients at home according to the test results. For positive patients, residents only need to wait in isolation at home, and special epidemic prevention personnel will come to help patients transfer to the receiving hospital for treatment.

In China, most of the large-scale nucleic acid detection adopts mixed detection mode to screen positive patients from samples. The epidemic prevention personnel in Gui 'an, Guiyang will also recycle these samples, and at the same time, some professionals will check and mix the results of the samples to prevent people from hiding them. As for the way of mixed inspection, family is the main way. Because family members are close contacts, if one person is infected with the virus, the whole family may be infected. The reason why epidemic prevention workers do this is also to improve the accuracy of virus detection and screen out suspicious patients and close contacts in the crowd.

So, what do you think should be done to improve the nucleic acid detection in China?
