They found that viable coronavirus could be detected up to three hours later in the air, four hours on copper, 24 hours on cardboard and three days on plastic and stainless steel.
The new coronavirus can live in the air for several hours and on some surfaces for as long as two to three days, tests by U.S. government and other scientists have found.
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. The tests were done at the National Institutes of Health’s Rocky Mountain Lab in Hamilton, Montana, by scientists from the NIH, Princeton University and the University of California, Los Angeles, with funding from the U.S. government and the National Science Foundation.
