The New Coronavirus Can Live On Surfaces For 2-3 Days — Here’s How To Clean Them

How long can the new coronavirus live on a surface, like say, a door handle, after someone infected touches it with dirty fingers? A study out this week finds that the virus can survive on hard surfaces such as plastic and stainless steel for up to 72 hours, and on cardboard for up to 24 hours.

“This virus has the capability for remaining viable for days,” says study author, James Lloyd-Smith, an assistant professor of ecology and evolutionary biology at the University of California, Los Angeles, who studies how pathogens emerge.

Although the World Health Organization had previously estimated the survival time on surfaces to be a “few hours to a few days” based on research on other coronaviruses, this is the first study by scientists at a federal laboratory to test the actual virus causing the current pandemic, SARS-CoV-2.

The study is out in preprint form and expected to be published.

Interestingly, some surfaces are less hospitable to SARS-CoV-2. For instance, the virus remained viable on copper for only about four hours.
