This @WHO review is really poor. No wonder they are spinning their wheels in this issue. They use a very very narrow view of evidence, as @CathNoakes explains

This @WHO-funded group would conclude "measles is NOT airborne" because it has never been cultivated from air samples!

And to my knowledge, @WHO has not funded similar reviews of large droplet or surface transmission. If they did, they would come up empty (e.g. nature.com/articles/d4158…)

Then we'd reach the startling conclusion that, according to @WHO, we have no idea how SARS-CoV-2 is transmitted

Apparently there is a similar review for fomite transmission. Similarly too narrow. Does conclude that "Lack of positive viral cultures and variation in cycle thresholds create uncertainty about fomites as a mode of transmission"

I wonder if they'll prepare one in large droplets and also conclude that we don't know.

(If it is out and I have missed it, let me know)
