Original title: Who will carry out antigen testing in Beijing? When will it be measured? How to measure? Understand the antigen test arrangement

On May 11, the Beijing 331st news conference on COVID-19 epidemic prevention and control was held. The reporter of Beijing Youth Daily learned at the meeting that Li Ang, the deputy leader of the quarantine and testing working group of the leading group for the prevention and control of COVID-19 epidemic in Beijing, the deputy director of the Beijing Municipal Health Commission, and the press spokesman, reported the detection of COVID-19 in key regions and industries of the city.

According to the situation of epidemic prevention and control in Beijing, in order to strengthen the mutual supplement and effective connection between antigen detection and nucleic acid detection, further improve the ability of "early detection", reduce the risk of cross infection, strive to achieve the maximum effect of prevention and control at the minimum cost, carry out key areas New coronavirus antigen detection for key industry personnel.

First, the scope of antigen testing personnel. It includes personnel in key areas, personnel in key industries and key risk personnel. Among them, personnel in key areas include those in closed control areas and control areas. Personnel in key industries include express delivery employees, imported non cold chain goods employees, farmers' markets and wholesale markets employees, catering units, supermarkets and other food business units, delivery and distribution employees, hotel and hotel employees, taxi drivers (including online car hailing), bus and subway staff, decoration, loading and unloading, and handling employees, Medical institution staff, environmental sanitation practitioners, property management, cleaning, security practitioners, public security, urban management law enforcement, market supervision and other front-line personnel. The scope of personnel shall be adjusted according to the development trend of the epidemic. Key risk personnel include nucleic acid mixed tube test positive personnel, high-risk personnel and Beijing Health Treasure "pop-up" personnel.

The second is the time node of antigen detection. For personnel in key areas, nucleic acid test shall be carried out once a day on the first, second, third, fourth, seventh and tenth days after sealing and control, and antigen test shall be carried out once a day on the fifth and sixth days. For personnel in key industries, during the local epidemic, in principle, antigen testing should be carried out once a day at the interval of nucleic acid testing currently specified. Among them, the nucleic acid and antigen testing requirements for delivery service personnel shall be implemented in accordance with the prevention and control guidelines for delivery service personnel issued by the municipal commerce department. For key risk personnel, after 1:5, 1:10 and 1:20 mixed tubes are positive, conduct antigen detection once while rechecking nucleic acid; For high-risk personnel and Beijing Health Treasure "pop-up window" personnel, on the basis of nucleic acid testing as required, antigen testing is conducted once a day every other day.

The third is the specific process of antigen detection. Antigen detection of personnel in key areas shall be carried out by the streets (towns) and communities (villages) organized by each district, and test kits shall be issued uniformly on the first day of sealing and control; Antigen testing for personnel in key industries shall be organized and implemented by the competent department of the industry; Antigen detection of mixed tube positive personnel in nucleic acid detection shall be organized and implemented by the area or unit that organizes the detection; The local community (village) shall urge relevant personnel to implement antigen testing for high-risk personnel and Beijing Health Treasure "pop-up" personnel. After the personnel in key areas and key risk personnel are tested positive for antigen, they shall immediately report to the community (village) where they live, and the community (village) where the residents live shall immediately report to the health commission and disease control department of the jurisdiction; After the personnel in key industries have tested positive for antigen, they shall immediately report to the competent department of the industry that organized the test, and the competent department that organized the test shall immediately report to the health commission and disease control department of the jurisdiction.

It should be noted again that nucleic acid testing is still the basis for the diagnosis of COVID-19 infection. Antigen testing is fast and simple. As a supplementary means for screening specific populations, it is conducive to improving the ability of "early detection", but it cannot replace nucleic acid testing.
