LOL Again with the Youtube videos. You do realize that aerosol virus particles are microscopic and can not be seen with a high speed camera? What you are seeing is water globules and vapor.

For the love of God, please read some actual science and forget about what you might learn on Youtube or Facebook.

To better understand how airborne SARS-CoV-2 transmission occurs, we sought to determine viral loads within coarse (>5μm) and fine (≤5μm) respiratory aerosols produced when breathing, talking, and singing.

Overall, fine aerosols constituted 85% of the viral load detected in our study

This is a study using actual covid infected patients and a very precise instrument called a G-II exhaled breath collector which can collect and measure particles down to 1um in size. 1um is 1 millionth of a meter or 1/25,400th of an inch. You need an electron microscope to see them, not a high speed camera
