On Friday, after a replacement COVID-19 cluster was found in a hospital due to insufficient disinfection, the Chinese coastal city of Qingdao completed testing of all its 11 million residents, a senior local official said.
Xue Qingguo, Qingdao’s Deputy Mayor, told the media that more than 10.16 million of the samples collected had been checked, and no new positive cases were identified.
He said that, after the advent of a new COVID-19 cluster, Qingdao has completed citywide testing of the nuclear acid of all 11 million people beginning on Monday.
Earlier in the day, Ma Lixin, deputy party head of the provincial health commission, said that insufficient disinfection in the CT room at the Qingdao Chest Hospital contributed to the city’s latest COVID-19 infection cluster.
The possibility for the latest cluster infections to be caused by cross-infection was also ruled out, the state-run Xinhua news agency says in a statement.
