Beijing has tested over 2.3 million people in the city 

A total of 2.342 million people in Beijing completed coronavirus tests between June 11 and June 21, municipal official told a media briefing on Tuesday. 

Over the same period, samples of nearly three million people have been collected as the Chinese capital is ramping up testing and screening in the wake of a local COVID-19 cluster, which first emerged on June 11.

At its peak, Beijing set up 2,422 sampling stations across districts, with 7,472 medical staff deployed. 

Zhang Hua, deputy director at the Beijing Municipal Health Commission, said Beijing can now administer more than 300,000 nucleic acid tests per day compared with 40,000 in March, and Beijing's mass testing for the new coronavirus will soon enter a "fast track."
