If this actually causes physical damage to a virus, it raises the question for me: what else do ultrasounds physically damage? Surely COVID 19 can’t be the only thing in our body with a resonance frequency in that range
All that to say, I don't think there's any cause here to draw suspicion upon sonograms or other time-tested procedures.
Also, the body regularly damages itself in attempts to eliminate infections. It then can heal. Ultrasound might damage other parts of the body, but it might not be worse than what the infection itself causes.
also consider that the cov2 virus is particularly fragile, for instance, requiring the external support of water to remain intact. it's why you don't need masks in most common situations (just distance), because the virus disintegrates so easily.
some viruses, on the other hand, can essentially hibernate and revive themselves once inside a host. those are the ones that would require enough excess energy that damage to other cells and organelles might be a genuine concern.
This does not take lots of energy, it does not take large amplitudes, just periodic input of power at the right frequency. Knowing that a system is fine at one frequency does not say (that) much about other frequencies.
the underlying point is that unless we're capable of doing the relevant experiments ourselves, we need to trust that people in the field are cognizant enough to realize these obvious issues, test them, and report their findings. it's unlikely that lay people like us are going to find and gotcha the researchers in the field.
that's not to say that, in aggregate, we can't give researchers ideas about what to be researching. that, we can--and should--do, via conversations like this.
I did not claim that the proposed method has to be harmful. I stated that ultrasound imaging gives little to no insight in what happens at frequencies that are an order of magnitude or two higher than that. The second reply was an attempt to do away with the misconception that "higher flux of energy" was necessary for damage.
"Ultrasound frequencies in diagnostic radiology range from 2 MHz to approximately 15 MHz" https://radiopaedia.org/articles/ultrasound-frequencies?lang...
So 10-50 times as high, but yeah.
