Source of Qingdao outbreak identified
China DailyMedical workers in protective suits collect swabs for nucleic acid tests during a city-wide testing in Qingdao, Shandong province, on Oct 11, 2020. The source of the recent coronavirus outbreak in Qingdao, Shandong province, came from overseas and has no connection with previous outbreaks in other Chinese cities, an expert said on Monday. "The city has reported no additional positive results in eight consecutive days, and it has achieved a staged victory in the latest fight against the re-emergence of COVID-19," Li Zhongjie, a research fellow at the Chinese Center for Disease Control and Prevention, said at a news conference in Qingdao on Monday. The source has been traced to two dock workers, and the spread was tied to poor disinfection procedures in CT scanning room shared by COVID patients and those with other conditions at Qingdao Pulmonary Hospital. In response to the outbreak, the city tested its nearly 11 million residents within five days, with no additional positive result beyond those already under quarantine.
