Tornado plot showing the sensitivity of epidemic properties to individual parameter changes: (A) the number of infected individuals (asymptomatic and symptomatic) at the epidemic peak; (B) the rate at which the epidemic peak is reached, tmax−1; (C) the total infected population after 30 days; and (D) the basic reproductive ratio (R0). Filled bars indicate the value of the epidemic feature when the associated parameter is increased by 5.0% from its nominal value. White bars indicate the value of a feature when the associated parameter is decreased by 5.0%. Blue coloring with checkered patterning indicates a parameter associated with survival, and orange coloring with lined patterning indicates a parameter associated with virulence.
