Ma Lixin, Secretary of the Party committee of Shandong Provincial Center for Disease Control and prevention: after comprehensive field epidemiological investigation, big data investigation and laboratory test results analysis by the national and provincial joint expert group, it was determined that the epidemic in Qingdao was a hospital aggregation epidemic, and the possibility of community transmission into the hospital was ruled out. Through comparative analysis, it was confirmed that the virus gene sequence of the epidemic was highly homologous with that of the infected people in Qingdao port in September.
Ma Lixin, Secretary of the Party committee of Shandong Provincial Center for Disease Control and prevention: the surveillance video of Qingdao chest hospital confirmed that two infected persons of Qingdao port had left the closed ward for CT examination during isolation observation in the municipal chest hospital. Due to the nonstandard protection and disinfection, the CT room was contaminated by the virus, and then infected the inpatient Li and the accompanying cattle who went to the same CT room for examination the next morning, and brought the virus into the tuberculosis area, resulting in the spread of the epidemic in the hospital.
