Estimation of transmission rates by transiently (β_T and persistently infected (β_P) animals, and disease-related mortality rate (μ^T) using Approximate Bayesian Computation (ABC)

	Parameters
Year of virus introduction	β T	β P	μ T
1991	0.009 [0.002; 0.028]	0.32 [0.20; 0.46]	0.64 [0.60; 0.70]
1992	0.032 [0.003; 0.039]	0.32 [0.20; 0.43]	0.66 [0.60; 0.70]
1993	0.010 [0.002; 0.035]	0.37 [0.24; 0.51]	0.69 [0.67; 0.75]
1991 – homogeneous contact	0.009 [0.002; 0.028]	0.35 [0.23; 0.50]	0.64 [0.60; 0.70]

Three years of virus introduction were tested. For the most probable year of introduction, estimation was also carried out with the model assuming homogeneous contacts all year long. Median and 95% confidence intervals (in brackets) are provided. Units are the same as in Table 1.
