Do those who live alone still take part in the city screening?

Do not participate. City-wide screening refers to the national screening of nucleic acid detection. All-staff screening is aimed at all people in an area, and people who are isolated at home do not need to participate in city-wide screening. Medical observation of home isolation (referred to as home isolation) refers to close contacts and special people, entry personnel who implement "14+7", discharged patients and asymptomatic infected people who have been released from isolation, and other professionals.
