Post-Lockdown SARS-CoV-2 Nucleic Acid Screening in Nearly Ten Million Residents of Wuhan, China

Emphasis mine:

“The screening of the 9,865,404 participants without a history of COVID-19 found no newly confirmed COVID-19 cases, and identified 300 asymptomatic positive cases with a detection rate of 0.303 (95% CI 0.270–0.339)/10,000.”

“A total of 1174 close contacts of the asymptomatic positive cases were traced, and they all tested negative for the COVID-19.”

“Virus cultures were negative for all asymptomatic positive and repositive cases, indicating no ‘viable virus’ in positive cases detected in this study.”
