Fomites Classification Parameters and Derived Parameter Values.

ahighly touched small surface.
brarely touched small surface.
chighly touched large surface.
drarely touched large surface.
eThe sum of ρptr for the four fomite types is 0.75, which is the same value as that in [4].
fWithin the venue we assume that there are many realizations of the same type of fomite, and that there are 250 fomites of each type and a population size of 1,000. For a small surface, we assume the ratio of finger area to one of the small fomite surface area is 0.3, therefore the ratio of finger area to the total surface area of the small fomite is 0.0012. The ratio of finger area to the total surface area of the large fomite is 0.0012 divided by 29.
