Even though common mask materials block most of the droplets that spread the virus, that may not be enough at close distances. Simply wearing a…
The cough-generated droplets from a walking individual disperse differently in a narrow corridor and an open space. In narrow corridors, the droplets are concentrated in…
Understanding Dangerous Droplet Dynamics New fluid dynamics research reveals why social distancing alone doesn’t necessarily prevent infection indoors and how to detect COVID-19 super-spreaders. Researchers…
Face masks slow spread of COVID-19; types of masks, length of use matter. The use of face masks to help slow the spread of COVID-19…
