Dr. Busch says the new strain causes brain and spinal cord disorders and has a high death rate. Two more common strains of EHV are non-lethal.

The horse had a high fever, neurological symptoms and nasal discharge.

The farm is under a 21-day no-move quarantine to make certain that no other horses have come down with the disease.
