Read full article: The new coronavirus can last on surfaces for up to three days, study saysThe 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 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. 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.
