Ruili City, southwest China's Yunnan Province, on Tuesday launched its second round of nucleic acid testing, which includes all residents of the city proper. 

The city is sparing no effort to control the spread of the novel coronavirus after new cluster infections were reported in late March. 

At a designated hospital specializing in traditional Chinese medicine treatment in the border city of Ruili, medics and experts are making an all-out effort to treat the patients.

"The workload was quite heavy initially but it is getting much less stressful after the arrival of medics from other regions," said Wang Huaiti, director of the rehabilitation department of the hospital.

On Monday, the city added three high-risk and three medium-risk areas for the COVID-19 outbreak. It also launched a citywide vaccination drive on Friday to vaccinate all people qualified for vaccination among its 300,000 residents in about five days.

As of  Monday afternoon, a total of 126,358 doses of COVID-19 vaccines had been administered in the city. "I feel safer after receiving the jab," said Hu Jianyong, a local resident.

Yunnan reported two new locally transmitted COVID-19 cases on Tuesday. As of Wednesday, the province had 68 confirmed cases and 46 asymptomatic cases all receiving treatment or under medical observation in designated hospitals.

From March 31 to April 1, Ruili completed COVID-19 tests for more than 300,000 people in the city proper. "Nucleic acid test is a precise measure to curb the epidemic," said Yang Mou, Ruili's vice mayor.
