The central Chinese city of Wuhan conducted 6,574,093 nucleic acid tests to screen novel coronavirus infections between May 14 and 23, according to the local health authority.
According to the Wuhan Municipal Health Commission, the city performed 1,146,156 tests on Saturday alone, more than 15 times the figure on May 14, when Wuhan kicked off a citywide testing campaign.
The largest single-day number was on May 22, when the city of about 10 million people performed 1,470,950 nucleic acid tests.
The decision to expand the tests to cover all those who have not been tested before was made as Wuhan continued to report asymptomatic infections.
Prior to the campaign, the city had completed over 3 million nucleic acid tests.
