Source: Arizona Department of Agriculture
Number Confirmed: 1
Number Exposed: 36
Facility Type: Racetrack
Comments: The index case is a single 14 year old Thoroughbred gelding that developed clinical signs of illness (hindlimb ataxia, weakness, difficulty rising / maintaining a standing posture) on 2-14-2023 with positive test results reported out on 2-18-2023 for EHV-1 variant D752. 36 horses from barns C9 & C8W were quarantined. Out of an abundance of caution, Turf Paradise has restricted movement from the backside until further notice. Biosecurity protocols were implemented including twice daily temperature monitoring of all horses in the quarantined barns, movement controls, and area disinfection. A second horse, (4 year old, filly Thoroughbred racehorse, was reported in Barn K6 to be ill. This horse had raced on 2/18/2023 and was claimed from barn D9. Clinical signs included depressed attitude, fever, and leaning on the stall wall. This horse was referred to a Phoenix-area equine hospital for diagnostics & treatment. Because of the close proximity to the confirmed case, this was treated as a suspect EHV-1 case until test results were known and barns K6 and K5E as well as D9 and D9W were placed under quarantine. Test results of the second horse came back negative for EHV-1. Repeat serial testing of the index case came back negative on 2-23-2023 and the horse is recovering.
