Update on EHV-1 in Washington State

Snohomish, Wash., March 29, 2012– As a leading provider of equine veterinary care in Western Washington, Pilchuck Veterinary Hospitalis closely monitoring recently reported cases of equine herpes virus-1 (EHV-1) in the state.

As of this announcement, Washington now has four confirmed positive cases of the non-neurotropic form of EHV-1, per the state veterinarian. Currently, only two facilities are affected. Both facilities are following voluntary quarantine recommendations and are monitoring the remaining horses for any new cases. Three of the cases did attend the HITS Desert Circuit in Thermal, Calif., in early March. The fourth horse is considered a secondary exposure.

Pilchuck is continuing normal business at this time, but will not be accepting elective procedures on horses that attended the recent HITS show.

As always, Pilchuck encourages good biosecurity. To limit further spread of this virus, Pilchuck makes the following recommendations for any horses that were at the HITS show in Thermal within the past three weeks:

  • Take temperature at least two times daily, and call your veterinarian if a temperature of greater than 101.5 degrees is recorded.
  • Monitor for any signs of respiratory disease, such as cough or nasal discharge, and call your veterinarian if any signs are noted.
  • Call your veterinarian immediately if there are any neurologic signs, such as hind limb weakness or difficulty urinating or defecating.
  • Do not transport any horses that were either at the HITS show in Thermal or in contact with horses from that show within the past three weeks. Minimize contacts with any new horses.
