Good grief. I noted this last April – over the span of 3 days the public health quacks went from face masks do not work when used by the public to everyone should wear a home made mask, made of random bits of cloth, using unproven random designs and assembled by persons of unknown skill. And this, in spite of overwhelming number of papers finding that N95 masks appear to work, certified surgical masks are helpful, and zero evidence that home made cloth masks reduced the spread of the disease. Zero and is none.
To anyone with a functioning brain cell (which means not public health experts) this was to be expected:
PARIS (Reuters) – The French government is now recommending that people wear surgical masks in public because they offer better protection from COVID-19 transmission than fabric face coverings, Health Minister Olivier Veran said on Thursday.
And once again, miraculously this comes out on January 21st, 2021. Beats us as to why all the common knowledge has changed overnight.
The use of ineffective masks is likely what explains this. I have repeatedly asked “experts” for a unified theory to explain this and they do not answer. Now we may know why.
