“It can tell us about the virus without us needing to stick anything up anyone’s noses or even know who was in a space,” said Dave O’Connor, a UW-Madison researcher involved in the surveillance. “Air sampling should be something that lots of schools bring on board to understand what the respiratory virus transmission risk is.”
Monitors have been at seven schools in the Oregon School District for two years, where air sampling last school year tracked flu and COVID-19 activity as reliably as student absences, rapid tests at school and regular tests from samples collected at home, UW-Madison researchers recently reported. That research was part of a UW study, funded by the Centers for Disease Control and Prevention, that has analyzed respiratory illness at Oregon schools since 2015.
