““It is possible for people to be infected through contact with contaminated surfaces or objects (fomites), but the risk is generally considered to be low,” the new CDC guidance says, estimating that the chance of contracting the coronavirus through surface transmission is lower than 1 in 10,000.
he coronavirus is spread almost exclusively by airborne and aerosolized particles, as scientists have known for months. Despite scientists’ growing certitude about how the pathogen is transmitted, many establishments have continued to insist on strict sanitization protocols. In some school districts, for example, classrooms close for full-day “deep cleaning.”
The persistence of such practices has led to the advent of a derisive term — “hygiene theater” — to describe rituals that appear to do little to stop the virus from spreading. It is not clear if the CDC’s new guidance will lower the curtain on those theatrics, given how entrenched some of those practices have become.
“If we took half the effort that’s being given to disinfection, and we put it on ventilation, that will be huge,” University of Colorado atmospheric chemist Jose-Luis Jimenez told the scientific publication Nature for an article published last month.”
