Table 2. Model variables and parameters.

Compartments and parameterizations of an environmentally mediated infectious disease transmission model with dose–response and a latency period, Eq (3).

Variables
S(t)	Number of susceptible people
E(t)	Number of exposed people
I(t)	Number of infectious people
R(t)	Number of recovered people
W(t)	Concentration of pathogens in the environment
Parameters
γ	Recovery rate (per day)
κ	Rate at which individuals contact the environment (per day)
ρ	Volume of environment consumed (per contact)
V	Total volume of the environment
α	Deposition rate of pathogens per unit volume of environment (per day)
μ	Pathogen decay rate (per day)
ξ	Removal rate of pathogens; sum decay and pick-up rates (per day)
σ	Rate of moving from a latent to infectious state (per day)
Functions
f(⋅)	Dose–response function; probability of infection given a dose
