At least 10,000 students were quarantined in a city in the northeastern Chinese province of Liaoning after a Covid-19 outbreak.
The health authorities in Dalian city revealed that two student halls in the west zone of Zhuanghe's university town were vacated, adding that 3,291- now considered close contacts and "high-risk" inpiduals - were transferred to quarantine hotels.
The 7,884 students that lived elsewhere in the zone were not transferred to hotels, but were isolated in halls under "closed-loop management", and other areas locked down.
"Zhuanghe has directed emergency personnel into the university town to assist with student management and to prevent infections from getting out," Sun Gongli, acting mayor of Zhuanghe, said.
Although China's latest wave of infections, which started on October 17, had shown signs of easing, a spike in cases in Dalian has bumped up the total again.
The country reported 89 new symptomatic cases for Saturday, up from 75 a day earlier, according to a statement by the National Health Commission.
