The new coronavirus can last on surfaces for 3 days - study

The coronavirus driving the current pandemic can live on plastic and stainless steel surfaces for up to three days, researchers say in a study published as a letter to the editor in the New England Journal of Medicine.

And it can linger in aerosols -- the suspension of tiny particles or droplets in the air -- for three hours, the study says.

The study, funded by the US National Institutes of Health, was initially posted online last week, but further details were published in the letter Tuesday.

Essentially, the study finds that the stability of this virus SARS-CoV-2, which causes Covid-19, is "similar to that of SARS-CoV-1 under the experimental circumstances tested."

SARS-CoV-1 is the virus that sparked the Severe Acute Respiratory Syndrome (SARS) epidemic in 2002.

The results add to researchers' understanding of how long the new coronavirus can linger on surfaces and the air, though scientists have said more research is needed.

Some highlights of the findings, according to Tuesday's letter:

  • The new coronavirus was viable up to 72 hours after being placed on stainless steel and plastic.
  • It was viable up to four hours after being placed on copper, and up to 24 hours after being put on cardboard.
  • In aerosols, it remained viable "throughout the duration of our experiment" of three hours.

The study indicates that transmission of the new coronavirus is possible by aerosol and material, "since the virus can remain viable and infectious in aerosols for hours and on surfaces up to days," the researchers wrote.

"These findings echo those with SARS-CoV-1, in which these forms of transmission were associated with" spread in hospital settings, and in "super-spreading events," in which one case can trigger tens or hundreds of cases, the researchers wrote.
