Study in PLOS on how diseases can spread between apartments via shared ventilation
Airborne diseases like measles, influenza and COVID-19 can easily spread between units in multi-family buildings via a type of bathroom ventilation system commonly used around the world, new research suggests.
The study, conducted inside an older high-rise in Spain early in the coronavirus pandemic, adds to a growing body of evidence that airborne viruses can spread between separated indoor spaces, transmitting disease without face-to-face contact.
“We tend to think that if we shut the door in our apartment, we are safe and can’t get infected. But our study shows that, depending on the ventilation system in place, that may not be the case,” said senior author Shelly Miller, professor emerita in the Department of Mechanical Engineering at the University of Colorado Boulder.
