While there are many ways of spreading COVID-19, the best medical analysis currently is that the virus is transmitted via airborne events from aerosols. (That's a fancy term for breathing.) Perhaps, to stay safe, we might strategically avoid moments that produce the most aerosols.
COVID-19 aerosols
While there is much back and forth around how aerosols may impact the "correct" social distance, this has been a great concern to anesthesiologists, nurses, and technicians who have to place breathing tubes into patients (intubation) requiring mechanical ventilators. After all, they are only a few inches away from those respiratory aerosols, and they have no other way to be more socially or professionally distant. A new study should bring them, and us, some ease of mind.
