READ THIS SENTENCE aloud: With every passing word, an expanding blast of spittle spews from your mouththe more emphatic the speech, the greater the spray.
This mouth-made mist is the subject of a great debate about how the coronavirus hitches a ride from person to person. Virus-riddled globs can be inhaled, or even land in the eyes, potentially sparking infections in others. But for respiratory diseases like coronavirus, its long been thought these droplets are so large they will fall rapidly to the ground, inspiring public health recommendations such as cleaning surfaces and keeping six feet of social distance.
Other scientists, however, have become increasingly concerned that the novel coronavirus spreads through a more insidious routeas an airborne pathogen. Every sneeze, cough, spoken word, or even exhaled breath expels droplets in a continuum of sizes. The worry is whether the tiniestcalled aerosolscan harbor the SARS-CoV-2 virus and allow it to linger or float across a room, causing new infections.
In July, 239 scientists published a commentary in Clinical Infectious Diseases calling for the recognition of airborne transmission for COVID-19 based on a series of case reports and lab studies. Though debate remains over whether airborne coronavirus transmission happens outside of hospital settings, proponents say the public risks are too dire to wait for more research. They propose additions to health guidance, such as improving ventilation, and some are working on models to predict the hazards of this route of infection.

This is an issue that is well known among researchers and health care workers but has thus far been ignored in our public messaging.
