The study was compiled by 19 scientists from the Huazhong University of Science & Technology in Wuhan and by scientific institutions in the UK and Australia. Out of the nearly 10-million people in the study, only "300 asymptomatic cases" were found. Contact-tracing records showed that not a single case of COVID-19 could be traced to any of them. The false narrative of asymptomatic transmission has been the justification for lockdowns around the world. The CDC falsely claims that asymptomatic people "are estimated to account for more than 50 percent of transmissions" but there is no scientific data to corroborate this position. -GEG
The study, published in the November issue of the peer-reviewed scientific journal Nature Communications, studied 9,899,828 residents of Wuhan, screening them between May 14, 2020 and June 1, 2020.  See Post-lockdown SARS-CoV-2 nucleic acid screening in nearly 10 million residents of Wuhan, China.
