A specially formulated antimicrobial coating can keep surfaces clear of a human coronavirus for up to 90 days with just one application, a preliminary study said Friday, suggesting a new line of defense against COVID-19 by researchers at the University of Arizona (UA). Result: coated surfaces virus reduced by 90 percent in 10 minutes and by 99.9 percent in two hours.
Charles Gerba, a microbiologist at UA and the study’s senior author, informed about “the next advancement in infection control.”
“I think it’s mostly important for high-use surfaces like subways and buses, because you could disinfect them but then the next people that come in there will recontaminate the surfaces,” he added. But, “it’s not a substitute for regular cleaning and disinfecting, but it covers you in between regular disinfecting and cleaning.”
