On the 16th, Shanghai announced 3 new cases of local asymptomatic infections on the 15th, and responded to the concerns of netizens:
1. What is the life trajectory of local asymptomatic infected people?
3 cases of asymptomatic infection were diagnosed as asymptomatic infection due to abnormal results of routine new coronavirus nucleic acid test during the isolation and control period. At present, 22 close contacts of the above three cases of local asymptomatic infections in Shanghai have been traced, and centralized isolation and observation have been implemented. Terminal disinfection has been carried out on places where asymptomatic infected persons have been active.
2. How to isolate close contact, close contact, and screening personnel? How many days in quarantine?
According to the relevant prevention and control requirements of the state and Shanghai, close contact personnel should implement 14-day centralized isolation medical observation + 7-day home health monitoring, and carry out nucleic acid testing at the corresponding frequency; close contact should implement 14-day centralized isolation medical observation, and carry out Nucleic acid testing at the corresponding frequency; screeners implement corresponding control measures and nucleic acid testing according to different situations.
3. Can disposable medical surgical masks prevent the spread of Omicron?
Droplet transmission is the main route of transmission of respiratory infectious diseases. For ordinary citizens, standardizing the wearing of disposable medical surgical masks in daily life can greatly reduce the risk of infection. Of course, you must also remember to change the mask regularly. When taking off the mask, you should prevent your hands from touching the outer surface of the mask. Wash your hands or disinfect your hands in time after taking off the mask.
4. What happened to Shanghai Aurora Vocational College?
According to the relevant prevention and control requirements of the state and Shanghai, the places and personnel involved in the local asymptomatic infection shall be investigated, and corresponding control measures shall be implemented.

Zhang Wenhong: There are two prerequisites for the “minimum risk area” of milk tea shops. The current round of epidemic prevention in Shanghai has become a closed loop
“The cases in this wave of epidemics were all found during the screening of close contacts. The number of cases was very limited, and they ran ahead of the virus, forming a very good closed loop.” On the 15th, the director of the National Medical Center for Infectious Diseases, Zhang Wenhong, director of the Department of Infectious Diseases at Huashan Hospital Affiliated to Fudan University, analyzed the current round of the epidemic in Shanghai in an interview with CCTV News “The Theory of Relativity”.
Shanghai reported 2 local confirmed cases and 3 local asymptomatic infections on the 13th, all of which were related to an overseas imported asymptomatic infection reported by the city on the 11th. Zhang Wenhong introduced that Shanghai currently implements 14-day centralized quarantine and 7-day home health monitoring management measures for inbound personnel. This round of epidemic is caused by the failure of home quarantined personnel to obey relevant policies. At present, he is also summarizing how to further strengthen the “14+7”. “Personnel management, laws and regulations must respond.
Among the above-mentioned 5 personnel, 3 are service personnel of a milk tea shop at No. 228, Yuyuan Road, Jing’an District. The milk tea shop is listed as a medium-risk area, and netizens call it a “minimum medium-risk area”. Zhang Wenhong told CCTV News “Relativity” reporter Zhuang Shengchun that this is because the current round of the epidemic in Shanghai is at a very early stage and the transmission chain is clearly visible. Second, the big data tracking is in place, and most people in the surrounding neighborhoods have never entered this milk tea shop. If widespread community transmission has occurred, the delineation of risk areas will need to be adjusted accordingly.
“Shanghai has not deliberately pursued the so-called minimum impact in terms of prevention and control,” Zhang Wenhong explained. If the leakage of patients has a great impact, the so-called “minimum impact” goal cannot be achieved. His team made a wide-ranging comparison of the Omicron and Delta viruses, and the former caused no less fever than the latter. “From this perspective, Shanghai’s precise prevention and control, as long as it involves risk areas, must be done in place, and must not be blindly expanded.”
