Coronavirus can live in the air for several hours, on some surfaces for several days

“We’re not by any way saying there is aerosolized transmission of the virus,” but this work shows that the virus stays viable for long periods in those conditions, so it’s theoretically possible, said study leader Neeltje van Doremalen at the National Institute of Allergy and Infectious Diseases.

Since emerging in China late last year, the new virus has infected more than 120,000 people worldwide and caused more than 4,300 deaths — far more than the 2003 SARS outbreak caused by a genetically similar virus.

For this study, researchers used a nebulizer device to put samples of the new virus into the air, imitating what might happen if an infected person coughed or made the virus airborne some other way.

They found that viable virus could be detected up to three hours later in the air, up to four hours on copper, up to 24 hours on cardboard and up to two to three days on plastic and stainless steel.
