Disease Alerts

On 4/27/18 the Wyoming Livestock Board received negative laboratory results for Equine Herpesvirus (EHV-1) in a blood sample from a horse in Carbon County. The horse had been showing hind limb neurologic symptoms. Nasal swabs had not been taken. Still concerned about EHM, the owners were advised to impose a self-quarantine and closely monitor all horses for EHM symptoms including temping two times daily. The veterinary clinic was advised to maintain isolation and resubmit both blood and nasal samples. On 5/2/18 the results on nasal swab were reported as positive for EHV-1 wild type. The premises was placed under quarantine with continued close monitoring on all 16 horses.The affected horse had attended high school rodeos at Laramie on April 7th and 8th, 2018 and Rock Springs on April 14th and 15th, 2018. Any horses at either of these events potentially could have been exposed as well and should be monitored closely preferably taking temperatures twice daily. Any horses with fevers (101.5 or higher) or showing respiratory or neurologic symptoms should be isolated immediately and their veterinarians consulted as to ongoing management. One horse from this premises NOT showing any signs of infection or disease attended the high school rodeo at Big Piney. While risk is minimal, horses at that event should be monitored as well.
