Post-lockdown SARS-CoV-2 nucleic acid screening in nearly ten million residents of Wuhan, China
https://www.nature.com/articles/s41467-020-19802-w
Newly released study at the link above: Out of 10 million people screened only 300 were asymptomatic positive. This is a very low rate of asymptomatic disease. A main reason for this lockdown, and the main reason behind healthy people wearing masks, was asymptomatic transmission. According to this large study, asymptomatic transmission is not a problem.
Equally important, only 60% of those 300 asymptomatics who tested positive by PCR were then confirmed positive by viral culture. The false positive rate of PCR testing was 40%. In other words, the number of “cases” we keep hearing about is highly inflated.
Make sure something is actually an issue, before passing sweeping regulations pertaining to said issue.
Caveat emptor: While this study appears to be honest, I am skeptical of any reports from China and skeptical of the peer review process at Nature publications. Both operate with agendas in which the truth and facts are not important unless they happen to serve their agenda.
