East China’s coastal city Qingdao has locked down some parts of local residential compounds and hospitals after three asymptomatic COVID-19 patients were found on Sunday.
As per preliminary investigation, the cases were all related to the Qingdao Chest Hospital, which has been receiving COVID-19 patients from overseas, Qingdao health officials said. The source of infection is under investigation.
The city’s anti-epidemic group has locked down the residential compounds where those patients live, as well as the Qingdao Chest Hospital and emergency department of Qingdao Central Hospital where the patients had been treated.
Close contacts will be given nucleic acid tests. On September 24, Qingdao reported two asymptomatic cases in a routine test of workers involved in cold chain production.
