A total of 168 cases of positive infection were detected in five rounds of nucleic acid in Shenyang, and the city was upgraded and controlled.

　　According to "Shenyang Released" WeChat WeChat official account News, on March 28th, the Information Office of Shenyang Municipal People’s Government held a press conference to release the latest news on epidemic prevention and control. Wang Ping, deputy director of the Shenyang Municipal Center for Disease Control and Prevention, said that at present, Shenyang has carried out five rounds of nucleic acid testing for all employees, and a total of 168 cases of positive infections have been detected. From the fifth round alone, there are 22 cases of positive infections, including 7 cases in the social sector. This shows that the citizens are still in a state of mobility, and the mobility is bound to cross-infect, and some Covid-19-positive infections are still detected in the social sector; The distribution area of positive infected people has expanded, and epidemiological investigation shows that the infected people have a complex track and a wide range. Especially, the Omicron mutant strain that caused the epidemic has the characteristics of strong concealment, fast transmission speed, short incubation period and inconspicuous symptoms. Only by reducing the flow and gathering of people as much as possible can the virus spread be blocked as soon as possible. To this end, through the full-scale nucleic acid test as soon as possible, the positive infected people will be screened out and screened clean, and the life safety and physical health of the citizens of Shencheng will be protected to the maximum extent. After comprehensive judgment by the national, provincial and municipal expert groups on epidemic prevention and control, it is decided to upgrade Shenyang.

　　During the period of upgrading control, the personnel in the sealed-off area with cases and the designated middle and high-risk areas shall stay indoors in strict accordance with the requirements of the sealed-off area, and live in single rooms when conditions permit; The control area should also strictly enforce that people do not leave the community (village) or gather, and the prevention area should implement "strengthening social control and strictly limiting the scale of people gathering" and participate in sampling at the specified time and place.
