How long can the coronavirus live on surfaces
An analysis found that the coronavirus can remain viable in the air for up to 3 hours, on copper for up to 4 hours, on cardboard up to 24 hours and on plastic and stainless steel up to 72 hours.
|Surface||Life span (estimated)|
|Cardboard||24 hours (1 day)|
|Stainless steel||72 hours (3 days)|
|Plastic||72 hours (3 days)|
The researchers compared the new coronavirus life span on surfaces with that of the SARS coronavirus in a 70-degree Fahrenheit room at 40% relative humidity. They found that both coronaviruses lived the longest on stainless steel and polypropylene, a type of plastic used in everything from Tupperware to toys. Both viruses lasted up to three days on plastic, and the new coronavirus lasted up to three days on steel.
