Can ultra-high resolution, ultra-high framerate and ultra-high zoom camera's measure exhalation of virii particles out of a humans mouth?

I'm actually curious: how many 'virus particles' does a person need to be exposed to on average to contract the virus?
Surely only 1 is enough, otherwise how does the first one spread in the first place?
I have an ozone vegetable washer. Is it dangerous to be in same room when this vegetable washer is running ? I can smell the odour of ozone near the vegetable washer
So you can smell ozone well before it is in the harmful range. Some air circulation wouldn't hurt while the device operates, but napkin math says you are OK.

Wow, okay - that explains why we're not doing this already! I'm curious as to why this logic doesn't apply to the electrostatic precipitator. Or maybe it does and we just have too much capacitance? https://en.m.wikipedia.org/wiki/Electrostatic_precipitator ETA: the EP causes Corona discharge, which doesn't sound like it would be too pleasant if you were the electrode.
Using the size of aerosolized droplets (0.35-10um) and the mass of human skin (20 lbs) would knock two orders of magnitude off, and drop the floor estimate to 50 megavolts.
"The Multiple Wave Oscillator is a combination of a high voltage Tesla coil and a split-ring resonator that generates ultra wideband electromagnetic frequencies."
The ionization of the air in the main room was quite intense, with plasma freely forming coronas.
Once the pandemic is over, you can drive out to get a 'sound bath' in the room, if you are so inclined.

The mass difference between humans and viruses is something like 10^19. So if you take the naive approach -- which is wrong, because charges live on surfaces, not in volumes -- you would want the person to have about a coulumb of charge to ensure that 1 extra electron was allocated to each virus particle. Whether or not 1 electron per virus is enough is a separate question, but that gives you a lower bound -- if you…

[0] Assuming the capacitor didn't fail -- in the case of actual capacitors, they only operate within certain parameters and tend to explode outside of them, in the case of people in an atmosphere, you'd probably see those discharges well before you managed to shove a full coulomb of charge onto one.
