Equine Herpesvirus- Respiratory

Louisiana, United States

Alert ID: 415

January 04, 2017

On January 3, 2017 a horse in barn #47 spiked a fever and was tested PCR negative for EHV1 on blood sample and positive for EHV1 non-neuropathogenic or wild type strain on nasal samples. The horse had recently undergone a throat surgery and had a history of EIPH but no neurological signs were present. The horse has been placed in isolation and barn #47 has been placed under official quarantine with twice daily monitoring of temperatures and enhanced biosecurity. To date there are 4 barns under quarantine and 4 horses in isolation quarantine. The index horse that was PCR positive for the neuropathogenic strain was euthanized. LDAF, USDA, and Racing Commission veterinarians continue to work with track personnel in monitoring the incident.
