Equine Herpesvirus- Respiratory
Louisiana, United States
Alert ID: 413
January 03, 2017
On January 2, 2017 a horse in quarantine barn #14 spiked a low grade fever with no other clinical signs and was isolated for testing. Another horse in the receiving barn that had been treated for a knee condition spiked a high fever with no other clinical signs and it was quarantined to the barn for testing at the LA Animal Disease Diagnostic Lab. The horse from barn #14 had PCR testing results on blood, nasal swabs, and nasal lavage that were negative for EHV-1. That horse will be tested again in 72 hours. The horse from the receiving barn had PCR testing results on blood, nasal swabs, and nasal lavage that were positive for EHV-1 non-neuropathogenic or wild type strain. That horse was placed in quarantined isolation and the receiving barn and horses there were placed under quarantine. Due to the nature of the receiving barn where day riders are required to check in, the Fairgrounds Racetrack is now under movement restrictions with no horses allowed to enter or leave. Racing will continue at the track. Movement restrictions are also in place at Delta Downs Racetrack in Vinton, LA due to the day racers that visit both tracks. Racing will continue at Delta Downs also. Epidemiological investigations into movements on and off of both tracks are on-going and LDAF, USDA, and Racing Commission veterinarians continue to work with track personnel in monitoring the incident.
