The very first two lines of that study:
– “Stringent COVID-19 control measures were imposed in Wuhan between January 23 and April 8, 2020. Estimates of the prevalence of infection following the release of restrictions could inform post-lockdown pandemic management.”
Jan 23 to April 8 is eleven weeks. Essentially no COVID-19 was found five to eight weeks later. So eleven weeks of “Stringent COVID-19 control measures” wiped out COVID-19.
UK “lockdown” started on March 23 2020. So eleven weeks later, June 8, the UK could have been free of COVID-19, had the measures been “stringent”.
What is “stringent”?
