We know that coughing and sneezing spreads germs. Now, researchers say, so do singing, whistling and laughing!
Virologists at Singapore’s National University Hospital say singing produces an even stronger, “more penetrating plume of infection” than coughing. How do they know? Because the researchers used a gigantic mirror and high-speed camera to watch the splatter of saliva… and they figured out exactly how far those flu droplets flew when someone was singing!
So what’s the point of this research? Researchers can apply it to how far apart hospital beds need to be to prevent airborne infection. But for us, we should steer clear of strangers who are whistling on their way to work – and maybe avoid close contact with singers on karaoke night! Keep a minimum distance of 20 feet… and know that viral droplets can stay suspended in the air for up to 10 minutes.
