Client of Chinanews.com, February 25th (Zhang Xu) In response to the question of whether the community should be closed for management, He Qinghua, a first-level inspector of the National Health and Medical Commission's Disease Prevention and Control Bureau, said on the 25th that he must judge according to the risk level of the epidemic. In the middle-risk areas, the existing cases and epidemiological investigations and epidemic situation analysis are used as clues to determine the prevention and control management sites and personnel, and implement refined management. If it is an outbreak in a school, it must be accurate to the class, if it is public, it must be accurate to the workplace. In high-risk areas, it is necessary to restrict personnel gathering, and adopt closed management to restrict personnel access.
