East China's Anhui Province and northeast China's Liaoning Province have stepped up contact tracing and mass testing in efforts to contain the latest COVID-19 resurgence.

Health authorities in Anhui, where seven confirmed locally transmitted cases and seven asymptomatic carriers had been reported by Sunday noon, said all recent infections are related to an offline training session at a photo studio in Yu'an District of Lu'an City.

The cases so far are either session participants, studio employees, customers, or their close contacts, according to the provincial health commission.

Anhui on Thursday reported its first confirmed case in the recent COVID-19 resurgence, a 29-year-old female from Lu'an. As of Sunday noon, Lu'an had reported five of the seven confirmed cases in the province, while the other two emerged in the provincial capital of Hefei. All seven asymptomatic cases in Anhui were reported from Lu'an.

Gene sequencing analysis conducted by the provincial center for disease control and prevention found the coronavirus behind the cases were not the highly infectious mutant strains found in India and South Africa.

Epidemiologists are still working to determine the "patient zero," said Dong Mingpei, deputy head of the provincial health commission.

The cities of Lu'an and Hefei have both launched citywide nucleic acid tests in the wake of the new infections. As of Sunday noon, nearly 1 million people in Lu'an and about 170,000 people in Hefei tested negative for the novel coronavirus.

Experts have basically ruled out the possibility of mass infections in Anhui, Dong said.

Meanwhile, the second round of mass testing covering all 500,000 people in Bayuquan District, Yingkou City, Liaoning Province was launched on May 16. The district reported the majority of Liaoning's recent new cases.

As of 7 p.m. on May 16, Liaoning had reported nine confirmed locally transmitted COVID-19 cases in the latest virus resurgence, of which three were reported on May 16. 

According to the Yingkou municipal epidemic prevention and control headquarters, a confirmed case recently identified in Anhui had been treated in a clinic in Bayuquan District due to a sore throat, and the doctor who treated the case was later reported as an asymptomatic case.

Bayuquan District on May 16 closed all educational institutions and private clinics over infection concerns. 

The National Health Commission has dispatched a working group to guide the COVID-19 prevention and control efforts in Liaoning, the commission said on May 16.
