Chinanews client February 23 (Du Yan, Chen Hang, Li Jinlei) For the phenomenon of traffic jams in Xiangshan, Beijing Municipal Health and Health Commission spokesman Gao Xiaojun said at a press conference on the 23rd that the prevention and control tasks are still severe and complicated. You must not relax your vigilance or paralyze your mind. First, as of 14:00 today, there are still 97 suspected cases in Beijing to be ruled out, and the possibility of some suspected cases turning into confirmed cases still exists. Second, there are still 620 close contacts who may be diagnosed. Thirdly, with the increase of the resumption of work and production in enterprises and institutions, the life of citizens and interpersonal communication are gradually approaching the situation before the Spring Festival, and the frequency of interpersonal communication has increased, bringing new risks. Fourth, the increase in the number of people from outside Beijing returning to Beijing will also cause the accumulation of epidemic risks. Fifth, the possibility of local community infection and nosocomial infection exists at any time. Therefore, the prevention and control must not be lax and not at all sloppy.
