On December 17, during further investigation by the centralized quarantine medical observation staff, the nucleic acid test results of two people were found to be positive, both of whom were porters from Haohan Labor Service Company. All were diagnosed as asymptomatic patients with new coronary pneumonia and had been transported. In order for the province to focus on the Dalian Center’s isolation treatment treatment, the two people’s close contacts, the close contacts of the close contacts are conducting full investigations and the implementation of centralized isolation medical observation.
In accordance with the status of the epidemic situation and in accordance with the principle of “all inspections must be inspected”, a sampling team of 100 people was quickly organized to sample key populations overnight. The Municipal Health Commission focused on improving the efficiency of sampling, collection, transportation, testing, feedback and other linkages, and did everything possible to accelerate Progress of nucleic acid testing, mobilizing 5 nearby medical institutions with testing capabilities to perform nucleic acid testing, with daily routine testing capabilities of up to 12,000 tubes. So far, the work of collecting and testing nucleic acid from all members of the Green Town community has been completed. A total of 8,216 people have been collected and the test results are all negative.
Based on the work, life and travel trajectories of the infected people from Dalian Port Yidu Cold Chain Co., Ltd., two control areas of Yidu Cold Chain Enterprise Factory and Green Town Community were scientifically delineated and implemented strict closed management to further expand the implementation of centralized isolation.

It established 10 epidemiological investigation teams for the first time, focused on the case, and took full advantage of the work of “three audiences and five combined”, using big data and information technology support to further expand the scope and increase the research effort quickly and quickly. Conduct a comprehensive epidemiological investigation and commission it quickly to make sure there are no hidden dangers. At the same time, gene sequencing work was started simultaneously and the source of the virus was immediately traced. On day 18, the complete sequence of the genome of the new coronavirus was carried out in samples of asymptomatic infections and food packaging. The results showed that the virus conformed to the characteristics of the L2 branch of the European genotype L family. The results support that the source of transmission is from abroad; the entire genome sequence of asymptomatic infections is homologous. Sex is 100%, suggesting a common source of virus.
