Sorry SupraLies, I'm going to have to put the buzzer on your oxymoron.
In 2020 there was essentially no chance of asymptomatic COVID spread
"In this case, the carrier of rationality is a gigantic study conducted in Wuhan, China, of 10 million people. The article appears in Nature Communications, published November 20, 2020. "Post-lockdown SARS-CoV-2 nucleic acid screening in nearly ten million residents of Wuhan, China"
The conclusion is not that asymptomatic spread is rare or that the science is uncertain. The study revealed something that hardly ever happens in these kinds of studies. There was not one documented case. Forget rare. Forget even Fauci’s previous suggestion that asymptomatic transmission exists but not does drive the spread. Replace all that with: never. At least not in this study for 10,000,000.
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. Here, we describe a city-wide SARS-CoV-2 nucleic acid screening programme between May 14 and June 1, 2020 in Wuhan. All city residents aged six years or older were eligible and 9,899,828 (92.9%) participated. No new symptomatic cases and 300 asymptomatic cases (detection rate 0.303/10,000, 95% CI 0.270–0.339/10,000) were identified. There were no positive tests amongst 1,174 close contacts of asymptomatic cases."
Thus never a need for a (worthless and harmful) mask for an unvaccinated person that does not have symptoms.
