An excellent reader comment following an article in today's Guardian.

"The current case rate in England, taken as a seven day average, is 2,234 per million.

In Wales, where mask use and other restrictive measures have been in force for longer and are stricter, the case rate per million is 2,865, having been as high as 3,241 within the last few days.

Yet again, evidence that masks and other restrictions are effective in preventing Covid transmission is lacking, yet we are told that we must believe this assertion anyway, because apparently it's as obvious as gravity."

Yet again indeed. Another commenter said that there has never been evidence that masks have significantly reduced infection rates anywhere. There you go.

I've just tested negative, a few minutes ago. Later this morning I'm off to Morrisons to do a bit of shopping. I'll be forced to wear a mask.
