So, this shows that masks, distancing, and less crowded conditions work.
It’s just as likely that the type of clippers they used reduced the likelihood of transmission
or it shows the virus is less contagious with brief contact than thought
Yep. Toward the end of the article is this: “Studies have found that physical distancing and the use of a mask are the two best ways to prevent coronavirus transmission...This month, a study published in the Lancet medical journal found people should stay six feet apart and wear face coverings. It said the chance of transmission without a face mask was 17.4%, while that fell to 3.1% when a mask was worn.”
Of course, it’s the same Lancet magazine that recently published and later retracted the fraudulent study denouncing HCQ.
....Or possibly that summer works.
