Coronavirus Stays Stable on Surfaces for Hours

The stability of SARS-CoV-2 is similar to that of SARS-CoV-1, the original SARS. For example, SARS-CoV-2 is detectable in aerosols for up to three hours, up to four hours on copper, up to 24 hours on cardboard, and up to two to three days on plastic and stainless steel. These findings do not indicate why SARS-CoV-2 spreads more easily. Possible explanations include: high viral loads in the upper respiratory tract and the potential for persons infected with SARS-CoV-2 to shed and transmit the virus while asymptomatic.
