(Different strains in animals may yes be more transmissible. They mght bind less well to the recipient cell receptor. Or bind only to a receptor deeper in the lung. But this is observing how well, not how, they transmit.)
Side note: his comment about decreased O2 is garbage. 3% diff, small N, and the ppl had no subjective effect
I have noted he has put this in print before.
The intro suggests the harms are severe, but pulling the _citations_, which I should not have to spend my time doing, revealed that they were about acne.
He also wrote this piece on behalf of the @WHO, which was meant to support droplets, but actually proved ventilation was great because they didn't check their citations well enough.
Psst, in actual fact, @WHO's committee on COVID-19 transmission modes is logjammed by some of its members. They refuse to admit SARS-CoV-2 is in the air.
So @WHO has to quote any old doc mentioning "air" to get around its own committee
Not very actively, apparently, since it's April 2021 now and no change.
The clear statement that SARS-CoV-2 transmits via droplets (that fall to ground) is found also in @WHO's mask guidance from June 2020 @ apps.who.int/iris/handle/10….
