Post-lockdown SARS-CoV-2 nucleic acid screening in nearly
ten million residents of Wuhan, China
Discussion
The citywide nucleic acid screening of SARS-CoV-2 infection
in Wuhan recruited nearly 10 million people, and found no newly confirmed cases
with COVID-19. The detection rate of asymptomatic positive cases was very low,
and there was no evidence of
transmission from asymptomatic positive persons to traced close contacts. There
were no asymptomatic positive cases in 96.4% of the residential communities.[…]
In summary, the detection rate of asymptomatic positive
cases in the post-lockdown Wuhan was very low (0.303/10,000), and there was no evidence that the identified
asymptomatic positive cases were infectious.
