Dubious claim if anything. Anything can be blown through the air.

I will see your dubious claim assertion, and raise you.

There isn't a single published paper of an "infections virus" that involves a procedure where the "infections virus" has been independently isolated outside of the human body.
None.

The evidence for "infections viruses" existing outside of the human body simply doesn't exist.

Infact, the German Supreme Court ruled that the existence of the measles virus hasn't been established.

...even though the existence of the measles virus could be concluded from the summary of the six papers submitted by Dr. Bardens, none of the authors had conducted any controlled experiments in accordance with internationally defined rules and principles of good scientific practice (see also the method of “indirect evidence”). Professor Podbielski considers this lack of control experiments explicitly as a “methodological weakness” of these publications, which are after all the relevant studies on the subject (there are no other publications trying to attempt to prove the existence of the “measles virus”). Thus, at this point, a publication about the existence of the measles virus that stands the test of good science has yet to be delivered.

Interesting...

it seems debated whether or not the coronavirus travels through air.

I'm still waiting for the evidence that this "virus" (which was miraculously/impossibly discovered and Identified in mere weeks) has ever been isolated outside of the body.

The fundamentals of virus theory are dubious, at best.

The debates never discuss this inconvenient detail.
