The confirmed case was found in Changning district and the two others were found in Pudong New Area. The residences of the three cases, including one hotel in Pudong, were locked down and marked as high-risk zones.

A total of 104 close contacts and 194 secondary contacts have been identified and quarantined. Testing is underway and the results as of press time were all negative.

Vice-governors of the two districts said they have ensured the supply of daily necessities, medicines for the quarantined and made special arrangements for students who are taking high school entrance exams on Monday and Tuesday.

From July 3 to 10 Shanghai reported a total of 319 local COVID-19 infections, with 305 cases related to an outbreak in a karaoke club in Putuo district, said Yuan Zheng'an, a member of the municipal epidemic prevention and control leading group.

The city has launched joint inspections on companies in the cultural and entertainment industry to make sure they comply with epidemic prevention protocols.

In reply to concerns over discrimination against recovered COVID-19 patients in the job market, Yin Xin, spokeswoman of the municipal government, said government departments and companies should not create obstacles for those patients.

"Society should give more care to COVID-19 patients, not put labels on them and not let their work and life be overshadowed by the illness from which they've already recovered," Yin said.
