(Shanghai War Epidemic Record) Shanghai announced the traceability results of multiple clustered epidemics: all of them were Omicron BA.2.2 mutants
China News Service, Shanghai, June 18 (Reporter Chen Jing) Since June, several clustered epidemics have occurred in Shanghai.
At the press conference on the prevention and control of the new coronary pneumonia epidemic in Shanghai, Wu Huanyu, deputy director of the Shanghai Center for Disease Control and Prevention, said that the Shanghai Center for Disease Control and Prevention conducted viral gene sequencing on the positive infected persons in the related clustered epidemics, and the sequencing comparison has been completed. The results showed that the virus genotypes were all Omicron BA.2.2 variant strains.
According to reports, the Shanghai and district-level disease control departments have conducted a survey on the adjacent enclosed areas of Ruijin 2nd Road Street in Huangpu District, Hunan Road Street in Xuhui District and Nanjing West Road Street in Jing'an District, Red Rose Beauty Salon in Xuhui District, Suning Tesco (Wujiaochang) Store) and Baoshan District Grete Sports Park Gym and other epidemics have been traced back to the source.
Comprehensive analysis shows that the clustered epidemics caused by the adjacent enclosed areas of Xuhui, Jing'an and Huangpu and their associated epidemics are caused by the infection of the same epidemic virus strain, which is closely related to the spread of potential community epidemic risks in the area that were not detected and eliminated in time. association.
The outbreak of the Red Rose Beauty Salon in Xuhui District is a clustered outbreak of a unit. Based on the results of epidemiological investigation and virus gene sequencing comparison, the source of infection risk can be focused on the three districts adjacent to the Hewei District Xuhui Block (Lane 339, Changle Road). community outbreak.
The outbreak of Suning Tesco (Wujiochang Store) was a clustered outbreak in a place. Because employees came into contact with customers who had contracted the virus in the community at work, secondary infection and the spread of the epidemic were caused.
Combined with the results of epidemiology and sequencing, there is a high correlation between the epidemic situation in the gym of Greite Sports Park in Baoshan District and the epidemic situation in Suning Tesco (Wujiochang Store).
Wu Huanyu said that some problems have also been exposed in these epidemics. All departments and units must "guard the door and control people", find out the number of personnel, urge the nucleic acid testing work, and ensure that the site code must be scanned, Temperature must be checked.
On the 18th, two new local confirmed cases of new coronary pneumonia in Shanghai have been transferred to designated medical institutions for isolation and treatment.
The two are a 74-year-old man and a 50-year-old woman, both living in Jing'an District.
As of 16:00 on June 18, a total of 90 close contacts in Shanghai of the two cases of positive infection have been investigated in Shanghai, all of which have been quarantined and controlled.
No. 1290 Gonghexin Road (residential building), Gonghexin Road Street, Jing'an District, and No. 1059-1069, Liuying Road (north side), Gonghexin Road Street, Jing'an District, are listed as medium-risk areas.
According to the needs of Shanghai's epidemic prevention and control, starting today, Shanghai will carry out nucleic acid screening in two enclosed areas: one is the enclosed area of Hutai Road, Luochuan Middle Road, Pengyuepu River, and Zhongshan North Road in Jing'an District; the other is Lien District in Putuo District. The area enclosed by Shan Road, Huayin Road, Hutai Road and Zhongshan North Road.
Long Wanli, deputy head of Jing'an District, introduced that the activity of a positive infected person diagnosed on the same day in the previous 14 days was mainly in the enclosed area. The middle-risk area of Lane 163, Tanjiaqiao Road, Gonghexin Road Street, released on June 7, is also located here.
According to the comprehensive research and judgment of epidemiological investigation and risk assessment, it was decided to conduct a comprehensive screening of personnel and environment in this area, and implement 7-day closed management + 7-day home health monitoring.
It is reported that the total population of the enclosed area is 9,142.
Long Wanli said that the district has arranged special work classes to enter relevant areas to strengthen community workers, sanitation and epidemic prevention personnel, property personnel and community volunteers, and to do a good job in communicating with residents; providing household supplies for door-to-door delivery, residents seeking medical medicine, garbage Clearance and other service guarantees.
For special groups such as the elderly, pregnant women, and critically ill patients in the enclosed area, the district will implement "one-to-one" care services.
For the 13 students who took the general high school academic level examination today and tomorrow, a point-to-point nursing examination service will be carried out to ensure that these 13 candidates take the examination smoothly.
