Surface stability of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at 20% relative humidity (RH)

T (°C)	RH (%)	No. tests	k
24*	20	3	0.02 ± 0.004
35*	20	1	0.05
54.5	20	4	1.7 ± 0.42

T, temperature; RH, relative humidity; k, decay rate (log₁₀ TCID₅₀/mL loss per hour)

For each test, three replicate coupons were evaluated at each time point, and the data were fit to a linear model

*Data were previously published, and are included here for comparison
