The city of Ruili in southwest China's Yunnan Province started its third round of city-wide nucleic acid testing for COVID-19 on Sunday, the local government said.
Ruili, where new local clusters of cases have been identified, has concluded its second round of city-wide tests, with 18 samples positive for COVID-19. Totally 382,568 samples were collected and tested.
The number of cases found in the second round is significantly lower than the 90 cases in the first round, indicating that the potential cases and asymptomatic infected persons have been located in time, said Huang Zhaoying, deputy mayor of Ruili.
Strict measures will remain in place in communities, isolation venues, farm produce fairs and designated hospitals, Huang said.
As of Friday, 88 confirmed cases and 39 asymptomatic cases were receiving treatment or under medical observation in designated hospitals in Yunnan.
