a

One treated with zinc pyrithione (TC) and one untreated (UT).

b

Human coronavirus studies on other porous surfaces are presented for comparison. Limited comparison data from the literature for three coronaviruses are also presented.

c

Decay rates for current data based upon model predictions graphed in Fig. 1 and 2 and expressed in log10.

d

N/A means that no data were provided or that the experiment was not extended until there was no detection.

e

AH was not calculated because RH was not provided.
