Iowa Department of Agriculture and Land Stewardship Confirms a Case of Equine Herpesvirus in Linn County
DES MOINES, Iowa (May 26, 2020) – The Iowa Department of Agriculture and Land Stewardship has confirmed a positive case of Equine Herpesvirus (EHV) in a horse at a boarding facility in Linn County. The horse is a 14-year-old Paint mare and is showing neurological signs of EHV.
To prevent the virus from spreading, the positive horse and 18 other horses at the facility are quarantined for 21 days. The barn staff is monitoring the quarantined animals for clinical signs of EHV and taking their temperatures twice per day.
EHV can lead to herpesvirus myeloencephalopathy (EHM), a neurological disease that can damage the blood vessels in a horse’s brain and spinal cord. EHV does not pose any threat to humans or other species of animals.
EHV is common in large horse populations and is spread through the respiratory tract and nasal secretions. Most horses have been exposed to EHV at some point in their lives and most show no serious signs of illness.
The Department encourages horse owners and caretakers to monitor their horses for clinical signs of EHV. If a horse develops a fever, loses coordination, leans against a wall or fence to maintain balance, has nasal discharge, decreased urine output, hind leg weakness, lethargy or the inability to stand, the owner should call their veterinarian immediately.
To prevent EHV, horse owners should follow these husbandry and biosecurity best practices at all times:
- Work with a veterinarian to develop a good health program for your horse(s).
- Don’t share equipment with other horse owners.
- Don’t share water and feed buckets/troughs between horse(s).
- Wash your hands or use hand sanitizer before handling other horse(s) and again before touching your horse(s).
- After returning home from an event, isolate your horse(s) that attended from your horse(s) that did not attend. This will prevent the rest of your horses from being exposed to diseases that may have been contracted at the show.
If horse owners have questions or concerns about their animal’s health, they should contact their veterinarians.
