A recent Western-led study says two meters might not be far enough away if someone lets an uncovered cough loose in your direction—meaning sneeze and cough etiquette is more than a simple social nicety, but a key to stopping the spread of diseases like COVID-19.
“It’s pretty hard to avoid a cough,” said Mechanical and Materials Engineering professor Eric Savory. “By the time you react, it’s reached you.”
Teaming up with virologists at Sunnybrook Hospital, Savory recently explored cough airflows produced by human subjects naturally infected with seasonal influenza in order to better understand how the environmental conditions affect the physical transmission of the infection.
