Table 2. Parameter values used in the swIAV infection dynamics model.

Rate	Event	Sources	Base value	Variation in the uncertainty analysis
β1	Transmission rate due to infected animals I1	[16]	2.43a	-
φ	Susceptibility to reinfection	Best guess	0.75	0.50–0.75–1.0
βair	Between-batch transmission rate	Best guess	0.1	0.01–0.05–0.1–0.3–0.50–1
ε	Susceptibility to infection for piglets having MDAs	[16]	Mean = 0.39	-
γ1	Recovery rate for infected animals I1 (days-1)	[16]	1 / 6.1	-
σ1	Immunity waning after the first infection (days-1)	Projected from field observations	1 / 180	90–120–150–180–240–360
σm	Maternal immunity waning (days-1)	[39,40]	1 / 70	-

^a β₁ is 1.41 in the service room [16] as sows are reared in specific conditions (see “Parametrization” section for more details).
