The current focus centers on airborne transmission, said Dr. Lisa Miller, professor of epidemiology at the University of Colorado Anschutz Medical Campus. “What CDC is saying is they don’t think objects — or fomites, as they’re called in science literature — are the main way coronavirus spreads,” Miller said. “Based on the literature and the outbreaks that we’re seeing, it’s mostly a person-to-person respiratory spread. Things like your mail or currency don’t seem to be a major factor.”
