  • Simulated sunlight and matrix significantly affected decay rate of the virus. Mean decay rates (± SD) in simulated saliva, under simulated sunlight levels representative of late winter/early fall and summer were 0.121 ± 0.017 min−1 (90% loss, 19 minutes) and 0.306 ± 0.097 min−1 (90% loss, 8 minutes), respectively. Mean decay rate without simulated sunlight across all relative humidity levels was 0.008 ± 0.011 min−1 (90% loss, 286 minutes).

The preventive measures depend mainly on the understanding of the transmission routes of this virus, its environmental stability, and its persistence on common touch surfaces. In this review, we present the available data on the stability of coronaviruses (CoVs), including SARS‐CoV‐2, from previous reports to help understand its environmental survival.
  • Aerosol and Surface Stability of SARS-CoV-2 as Compared with SARS-CoV-1. Van Doremalen et al., 16 April 2020, N Engl J Med 2020; 382:1564-1567
    https://www.nejm.org/doi/full/10.1056/NEJMc2004973 en het supplement https://www.nejm.org/doi/suppl/10.1056/NEJMc2004973/suppl_file/nejmc2004973_appendix.pdf. In aerosol, the virus can survive up to 10 hours, half-life in aerosol in this experiment was calculated at approximately 1 hour. It is virulent on copper 4 hours, on cardboard 24 hours, on plastic and stainless steel 3 days. The humidity in the aerosol experiment was 65% and the temperature 21-23 °C. The humidity in the surface experiments was 40%. It has not been described how the virus behaves at other temperatures and humidity.

Coronaviruses can remain virulent on metal, glass or plastic for up to 9 days. Efficient disinfection procedures are also described.
