【Commentary】During the Winter Olympic Games, how does the aerosol new coronavirus nucleic acid detection system help the epidemic prevention work? On January 18, the reporter visited the Beijing Bioaerosol Testing Laboratory.

It is reported that the system is composed of two parts: an aerosol collector and a new coronavirus nucleic acid detector, which can carry out virus monitoring and early warning and rapid detection of the air, and the detection sensitivity is high.

Our whole system is composed of two parts to a piece, because in the air aerosol its new crown virus content is definitely very low, certainly lower than the throat of the patient, so this requires our entire system sensitivity is relatively high, including this aerosol its enrichment efficiency is high, can be the air aerosol can be enriched down. After the enrichment is done, our detection (system) must also be very sensitive, so that a very small amount of virus can be detected.

【Commentary】After layers of selection, the bioaerosol new coronavirus nucleic acid detection system was identified as one of the "Science and Technology Winter Olympics" projects. During the Games, it is expected to arrange aerosol collectors in various venues of the Winter Olympic Games to provide aerosol new coronavirus detection guarantee for the Winter Olympic Games.

The detection of personnel nucleic acids, the detection of environmental surfaces such as test strips, and the elimination of closed-loop management are a series of policies. Our technology is a link in the entire large technical system, to detect the air, not to directly detect people but to detect the new crown virus in the air, so as to play an early warning or early detection of the flame of the epidemic a role.

【Commentary】During the Beijing Winter Olympics Test Match, the detection system has carried out aerosol sampling and testing in competition venues such as the Capital Gymnasium and the National Speed Skating Hall. Through the application and verification of the test match, the detection system has been optimized accordingly, which is more in line with the requirements of the Winter Olympic games.

To really be able to apply this, it is not only the technology itself, which includes a lot of work in the scene of this kind of event, including how to distribute the personnel, how to collect samples, how to safely hand over, and then how to feedback the results and a series of chain things. So during the Olympics (test matches), on the one hand, we tested the effectiveness and reliability of our testing methods; on the other hand, we explored a way to effectively cooperate with various venues.

【Commentary】Up to now, more than 200 technologies have been tested and used in the Winter Olympics scene, involving information engineering and software engineering, public safety, high-definition video, 5G and new energy.
