Then throw all of them advising this into an active volcano.
Fact. The only purpose of masks in this context is for virtue signaling. In no way, shape, form or manner do they prevent the spread of ANY virus, let alone the more prevalent variants of the COVID-19 Wuhan virus.
Masks are probably fine for filtering out dust particles, but for virus protection, you might as well put a piece of mosquito net screening over your mouth and nose.
And testing for the presence of the COVID-19 virus by taking nose swabs does not prove or disprove any degree of infection, plus it is often meaningless whether or not such presence is determined, as conditions can change quite quickly between the pint in time when the sample is taken, and the samples are shown to be either positive or negative. Besides, of course, the very real possibility that the test itself failed to make that determination.
The only real and reliable test is for the presence or absence of specific COVID-19 antibodies circulating in the blood serum of the individual. But to do so would invalidate the whole argument that EVERYBODY must be injected with the mRNA vaccine, “just to be sure”.
