CSU lifts EHV-1 quarantine

FORT COLLINS, COLO. — A voluntary quarantine at Colorado State University (CSU) was lifted following a late October outbreak of equine herpes virus type-1 (EHV-1).

The University's James L. Voss Veterinary Teaching Hospital issued the quarantine after EHV-1 was diagnosed in two horses being treated for unrelated illnesses.

University officials moved to quarantine hospitalized horses. Five horses were ultimately infected with EHV-1. Four horses had mild fevers and one other developed mild neurological signs that are improving, the university reports.

Dr. Paul Morley, director of biosecurity for CSU's hospital, reports, "No horses from the hospitalized population have shown news signs of infection for two weeks, and all quarantined horses have tested negative on four consecutive tests for the virus."

No other veterinary activities were impacted by the quarantine, the university adds.
