Ohio State Study Shows Difficulty in Achieving Virus-Free Surfaces

Wiping surfaces with disinfectants might not be enough to protect against COVID-19 coronavirus because cleaning practices tend to be spotty, according to a new study from Ohio State University.

The study’s author, Jason Stull, said the results serve as a warning, and that “regardless of where you visit, it’s also best to assume surfaces may be contaminated.” He pointed to another study showing the COVID-19 coronavirus can survive for up to three days on a plastic or doorknob.

Stull recommends people concentrate on cleaning surfaces that are commonly touched, such as doorknobs and countertops, and urges that these efforts continue even after the COVID-19 crisis. 3/26/2020
