Authorities in wuhan have found more than 200 asymptomatic cases of the new coronavirus since launching an ambitious plan earlier this month to test all of the city’s approximately 11 million residents.
Aimed at preventing a resurgence of new infections, Wuhan's testing capacity has skyrocketed from 42,000 nets conducted on may 12 to a high of 1.47 million on Friday.
The so-called “mixed testing” approach that has allowed authorities to test on a mass scale in Wuhan has drawn questions about the efficiency of identifying infected cases.
