a Horse C2 was naturally infected with an EHV-5 that was designated as VC. This horse was in contact with other horses in the study before separate housing was initiated.
* Horses E1, E2, and E3 were experimentally infected with an EHV-5 designated as A
** Horses E4, E5, and E6 were experimentally infected with an EHV-5 designated as B -; negative; ND: not done; V: several genetically identifiable EHV-5 were detected in blood from the horses, those viruses are collectively designated as V. The age of all horses in years (y) is denoted in subscript.
