Aerosol and surface stability of HCoV-19 (SARS-CoV-2) compared to SARS-CoV-1
Abstract
33 HCoV-19 (SARS-2) has caused >88,000 reported illnesses with a current case-fatality ratio of ~2%. Here,
34 we investigate the stability of viable HCoV-19 on surfaces and in aerosols in comparison with SARS35 CoV-1. Overall, stability is very similar between HCoV-19 and SARS-CoV-1. We found that viable virus
36 could be detected in aerosols up to 3 hours post aerosolization, up to 4 hours on copper, up to 24 hours on
37 cardboard and up to 2-3 days on plastic and stainless steel. HCoV-19 and SARS-CoV-1 exhibited similar
38 half-lives in aerosols, with median estimates around 2.7 hours. Both viruses show relatively long viability
39 on stainless steel and polypropylene compared to copper or cardboard: the median half-life estimate for
40 HCoV-19 is around 13 hours on steel and around 16 hours on polypropylene. Our results indicate that
41 aerosol and fomite transmission of HCoV-19 is plausible, as the virus can remain viable in aerosols for
42 multiple hours and on surfaces up to days.
