Median with (5^th and 95^th percentiles) of epidemic duration, number of infected herds, number of diagnosed herds from surveillance, number of surveillance visits and the total costs of the epidemic, using the basic scenario (<b>Basic</b>) that represent the EU and Danish control measures, when epidemics were initiated in cattle herds in high (<b>highCat</b>) and low (<b>lowCat</b>) cattle density area, swine herds in high (<b>highPig</b>) and low (<b>lowPig</b>) swine density area and in sheep herds (<b>sheep</b>); The influence of changing the frequency of surveying herds located in overlapping zones from every 14 days to every 7, 21 or 30 days is compared.

1<p>Epidemic duration is calculated from detection of the first herd in the epidemic to the last herd is depopulated.</p>2<p>Statistical significance level in comparison to the corresponding variable in the corresponding basic scenario (absence of a star represents a P-value ≥0.05, * represents a P-value <0.05, ** represents a P-value <0.01, and *** represents a P-value <0.001).
