Stochastic scenario tree representing the BVD surveillance system for Danish dairy herds. PrPImpoCattle and PrPNoImpoCattle = proportion of dairy herds within the ImpoCattle and NoImpoCattle category, respectively. EPIImpoCattle and EPINoImpoCattle = effective probability of infection for the ImpoCattle and NoImpoCattle category. PTRImpoCattle and PTRNoImpoCattle = probability that the threshold prevalence is reached within the milking paddock at 90 or 365 days from BVDV introduction within herds of the ImpoCattle and NoImpoCattle category. Se = Expected sensitivity of the antibody ELISA used (Danish blocking ELISA or SVANOVIR) on BTM, when the threshold prevalence of seropositive milking cows is reached
