As any fan of musical theater will tell you, front-row seats might as well be labeled as the splash zone. Between projecting, enunciating, and breathing hard through a big song-and-dance routine, stage performers generate a lot of spit. That’s kinda gross under normal circumstances, but it’s downright unsafe during the coronavirus pandemic.
COVID-19 is a respiratory disease, and it travels in drops of saliva and mucus known as respiratory droplets. Someone speaks, sneezes, or sings, and virus-laden drops spew forth, landing on surfaces or in other people’s faces. That’s why we have the now common practices of wearing masks, washing hands, and social distancing. But evidence is emerging that the coronavirus might also move about in much smaller droplets suspended in the air, which has scientists and public health experts debating whether to officially consider it airborne.
It may seem like a question of semantics, but figuring out when and where coronavirus might linger raises a host of questions about best practices, especially as people consider going back inside restaurants and reopening schools, Maya Wei-Haas reports for Nat Geo. If tiny drops carrying the virus can float, they might then build up inside confined spaces, including buses and classrooms. Last month, more than 200 scientists put out a call for additional health guidance based on the current evidence for airborne transmission, including improving ventilation in public buildings. Jose-Luis Jimenez at the University of Colorado, Boulder, even led creation of a model that can help people figure out their relative risk from airborne exposure in offices, schools, public transit, and other settings.
The flip side is that while coronavirus may loft in the air in select circumstances, it does not appear to be as contagious that way as definitively airborne diseases such as the measles. As such, the label may create more fear than is strictly necessary. “The connotation to people is that, Well, if I simply walk by a person on the street who is exhaling, I’m going to get sick,” says Michael Klompas, a hospital epidemiologist at Brigham and Women's Hospital in Boston. “That, I think, is both an inaccurate and unduly fearsome kind of message.”
The bottom line for now is that people should definitely still use masks to avoid spitting all over the place, and that potentially stuffy rooms should be better ventilated whenever possible. Of course, Broadway has been shut down since mid-March, and it will remain that way until January 2021, NPR reports. But I dearly look forward to getting back to the theater—and hopefully by then, we’ll know far more about the best ways of keeping everyone inside safe and healthy.
