SARS-CoV is highly stable at room temperature and at 4 °C, but it is inactivated by ultraviolet light at 254 nm, highly alkaline or acidic conditions of pH >12 or pH <3, respectively, or by brief (e.g., 5 min) heat treatment at 65 °C. SARS-CoV-2 is expected to be similarly sensitive.150 Several human coronaviruses can be inactivated by classical disinfectants, including bleach, ethanol, povidone-iodine, chloroxylenol, chlorheximide, and benzalkonium chloride,151 so we expect similar inactivation with SARS-CoV-2. The virus stability on surfaces depends on the composition of the infected material, with inactivation in <3 h on printing and tissue paper, in <2 days on treated wood and cloth, in <4 days on glass and banknotes, and in <7 days on stainless steel and plastic.152 Conversely, active viruses can remain on the outer layer of a surgical mask even after 7 days.152 The surface and aerosol stability of SARS-CoV-2 is comparable to that of SARS-CoV-1,153 with both viruses remaining viable in contaminated aerosols for more than 3 h. Infectious SARS-CoV-1 and SARS-CoV-2 remain viable up to 72 h after inoculation on plastic and stainless steel, whereas both are inactivated on copper in less than 4 or 8 h, respectively, and on cardboards in less than 24 and 8 h, respectively.153 Therefore, the stability of both viruses is similar, and we can hypothesize that surface treatments with NPs that proved to be effective for SARS-CoV-1 could possibly also be effective for SARS-CoV-2.
