Why should asymptomatic infected persons be subject to centralized isolation and medical observation? Wu Jinglei, director of the Shanghai Municipal Health and Health Commission, said that the first is the reduction of the pathogenicity of the Omicron strain itself; the second is the vaccination of large-scale populations, which has played a very important role in protecting the majority of susceptible people; the third is active screening. After increasing the detection rate, more asymptomatic infected persons were screened. With the advance of epidemiological investigations, the screening capacity and scope became larger. After the outbreak, the relevant close contacts, second-close contacts, and risk groups were quickly identified. Take control.
