Small saliva droplets can remain airborne more than 10 minutes, NIDDK study shows
Показать описание
A recent study by the National Institutes of Health (NIH) shows that small saliva droplets generated by loud speech can remain airborne in an enclosed space for more than 10 minutes at a time.
In this video, a scientist from the NIH’s National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) speaks into an environment of stagnant air, repeating the phrase, “Stay healthy.” The laser light scattering shows thousands of miniscule saliva droplets that could contain virus particles.
COVID-19 is an emerging, rapidly evolving situation.

The laser light scattering shows thousands of miniscule saliva droplets that could contain virus particles. A fan was used to ensure the droplets were distributed evenly inside the space and was shut off 10 seconds after talking stopped.
These droplets remained airborne after talking. They stayed in the window of view on average for about 12 minutes.
