aOther: isolates did not correspond with a defined virotype.
bCharacteristics: For comparisons across all virotypes, the only statistically significant difference involved virulence gene scores (p < 0.01).
c VG score: Median virulence gene score (interquartile range).
d ISS: Median illness severity score (interquartile range).
e Rapid lethality.
