Dalian, Northeast China’s Liaoning Province, announced that it was extending the COVID-19 quarantine period to 21 days from 14 as the new cases in the recent COVID-19 outbreak in the city show a longer incubation period, faster transmission and more complex pattern.

Some patients tested positive for COVID-19 after taking 11 nucleic acid tests, while in some regions, cases were still found even after six rounds of mass testing, said Dalian authorities at a press conference on Monday.
