Could HVAC systems be used to detect COVID-19?
Researchers at East Carolina University’s Brody School of Medicine have been attempting to detect SARS-CoV-2 in a building by testing the air passing through the HVAC systems. The team hopes this could lead to earlier detection of the virus, improved quarantine protocols, reduced transmission, and fewer outbreaks. Researchers collected samples from two large student dormitories […]
