Just as a thought experiment.
Say 4 horses at KHP this weekend came down with EHV-1. How many people would be up in arms about pony finals being canceled? How many people would say 'we’ll sign a waiver! Let us show!" or “but we’ll stay in our own barn and only go to the arena to compete!” and all this other stuff you see people saying.
Why do we treat horse diseases and quarantines more seriously the HUMAN ones? The vast majority of horses with EHV-1 will have a fever for a few days and recover uneventfully with no long term effects. A small percentage will get neurologic signs, an even smaller percentage will be euthanized or die, not unlike covid-19. It boggles my mind that people won’t take a human disease as seriously as we take a horse one.
