ll data were analysed at animal group level, reflecting the animal groups followed and reported in the individual references. Some references reported more than one animal group.

b

Min = first day (in dpi) that pathogen/RNA was detected in a sample for each reported animal group; Max = last day (in dpi) that virus/RNA was detected in a sample for each reported animal group. Min and Max were recorded individually for each animal group, and median (min‐max) for each of those values were calculated from all group data (each group representing one observation, with no weighting based on the size of the animal groups). Contact transmission groups were not included in the summary.

c

Min = first day (in dpi) in which clinical signs were observed in each whole animal group reported; Max = last day (in dpi) in which clinical signs were observed in each whole animal group reported. Min and Max were recorded individually for each animal group, and median (min‐max) for each of those values were calculated from all group data (each group representing one observation, with no weighting based on the size of the animal groups). Contact transmission groups were not included in the summary.
