Can the Covid19 be airborne? Via airborne particles? Pollution, pollens, fog

[Christophe]

You still missed an opportunity to shut up to try to belittle the other members of this forum...

"Biological" microparticles were widely mentioned above, weeks ago, especially with the Japanese study ...

It dates from April 4th exactly: health-pollution-prevention / the-covid19-can-be-semi-aerial-via-the-particles-pollution-pollens-fog-t16375-70.html # p389488

Are you sure you read what others are writing here?

Micro "biological" particles have been widely mentioned above.

In theory but unlikely https://www.sciencesetavenir.fr/sante/e ... -19_143523

Do you know that you are quite serious at the level of self-contradiction ... just in order to disrupt the opinion of others?

I don't even want to explain your contradiction to you ... reread your last messages ... you're pitiful there ...

When I said biological micro particles it was about particles of respiratory origin ...

Another experience of visualizing fine expiratory particles through a visor and 2 types of surgical masks and N95 (FF3 with and without valve):

Every drop of rain is a natural (and inevitable) dispersant of fluids, gases ... and particles ... shall I continue or do you understand what I mean in this topic?

This subject alerted from March 25 on airborne transmission by aerosols, this is confirmed more than 6 months later by a Nature study on the data:

Covid and virus circulation: what the data tell us

CHRONIC. A study published in the journal "Nature" analyzes the displacement of 98 million Americans thanks to their cellular data recorded between March and May 2020.

(...)

If it had initially been thought that the transmission of Sars-CoV-2 was through the droplets of saliva excreted by infected people, we now know with certainty that the mode of contamination is mainly by aerosol, which is much more complex to control. In fact, in an enclosed space such as a restaurant, a single sick person can infect a large number of customers, without necessarily being seated nearby. The virus spreads in the ambient air and circulates in the confined space and can thus affect anyone, well beyond the recommended distance of meter fifty.

Yet it was obvious! the very nature of the masks or the breathing diffuse in all directions, since they are not waterproof masks, the humid "contaminated" air must come out somewhere.

Punaize ... 1 year to lay this study!

At the same time, it is not pollution, pollen or fog, but micro droplets that can move several meters and extremely unlikely outdoors.

There is nothing unlikely! If there are contaminated water droplets blown by the wind, it is only a matter of time to multiply a possible virus.

We already suspected it, it's confirmed: no need to cough to contaminate others ...
