The bottom line on this study, there was a 0.0% new covid positive tests resulting from "close contact" with people who were covid positive but not showing symptoms (asymptomatic).
Put another way...out of nearly 10 million people, only 300 were new covid positive but not showing signs of it and 1,174 people who were close to those covid asymptomatic's, nobody new got infected. Nobody.
This is evidence that the orthodoxy here in the U.S. and most of Europe that lockdown's, cloth mask wearing, "social distance" mandates and selective business closures are not based on "settled science" along the lines of the man caused globul warming scam...but rather, based on liberal politicians desire for power and control.
The take away is this...
If individual people (esp those with compromised immune systems & the very old) feel the personal need to put a cloth mask over their mouth or nose, then that is their individual right.
But governments, whether state or local (or soon federal) should NOT be in the business of mandating any such thing and should NOT be selectively closing down some businesses, while allowing others to remain open.
False. This study was done post-lockdown and claims relevance only in that context: "The citywide screening of SARS-CoV-2 infection in Wuhan is a mass screening programme in post-lockdown settings, and provided invaluable experiences or lessons with international relevance as more countries and cities around the world entering the post-lockdown phase."
