Findings from a study published in the New England Journal of Medicine may make you want to stand back the next time someone speaks, especially if he or she is infected with the COVID-19 coronavirus.

The study literally provided spitting images of what may happen when people talk and say the words, “stay healthy.” The researchers used lasers to track the size and path of droplets that came out of a person’s mouth while that person was speaking. They used a green laser to create a sheet of light that projected into a cardboard box through slits on the sides of the box. The insides of the box were painted black, to help them better film and see what happens to the sheet of light.

Next, they got a person to say things into the open end of the box. If anything more than words came out of the person’s mouth, they would only have to travel 50 to 75 mm before hitting the sheet of light. Anything that would hit the sheet of light could, as a result, produce light scattering or flashes. Thus, the research team could film the flashes produced by light scattering to determine how many droplets were generated (based on the number of flashes), their size (based on the brightness of the flashes), and their trajectories.

So with that set-up, the research team got the person to say something somewhat ironic: “stay healthy.” Speaking these words proceeded to launch numerous droplets, ranging in size from 20 to 500 μm, out of the person’s mouth. When this fan of droplets hit the sheet, it produced anywhere between 227 and 347 flashes, with more flashes being produced the louder the person said the words. The most flashes occurred when the person pronounced the “th” in the word “healthy.”

This is perhaps yet another reason why Thor said, “don't say that name,” when Hulk mentioned the name Thanos in the movie Avengers: Endgame.

Note: This is a brief compilation of the study. The complete study is attached as pdf.
