Kent County, RI
On April 19 the Rhode Island state veterinarian confirmed that a horse at a Kent County boarding facility tested positive for equine influenza (EI).

The horse, which reportedly had been purchased from a sale barn and imported into Rhode Island illegally, initially showed signs of fever and temporomandibular joint (TMJ) swelling. The treating veterinarian ran a respiratory panel, the results of which confirmed EI, and referred the horse to an equine hospital for TMJ treatment. The horse was euthanized due to the severity of its TMJ signs.

The boarding facility is under official quarantine, and caretakers are keeping a temperature log of the 15 exposed horses residing there. None are currently showing signs of EI.

About Equine Influenza

Equine influenza is a highly contagious respiratory disease that infects horses, ponies, and other equids, such as donkeys, mules, and zebras. The virus that causes it is spread via saliva and respiratory secretions from infected horses. Horses are commonly exposed via horse-to-horse contact; aerosol transmission from coughing and sneezing; and contact with human’s contaminated hands, shoes, or clothes or contaminated tack, buckets, or other equipment.

Clinical signs of equine influenza infection can include a high fever (up to 106°F); a dry, hacking cough; depression; weakness; anorexia; serous (watery) nasal discharge; and slightly enlarged lymph nodes. Consider monitoring your horse’s health at shows by taking his temperature daily, which can help you pick up on signs of infection early and take appropriate measures to reduce disease spread.

Vaccination is an important and inexpensive way to protect your horse. US Equestrian requires proof that horses have had an equine influenza vaccination within the six months prior to attending organization-sanctioned competitions or events. Your veterinarian can help you determine what other vaccines your horse might benefit from.

In addition to vaccinating, following strict biosecurity protocols can help reduce your horse’s chance of infection and disease. Such measures include quarantining new equine arrivals at barns, disinfecting buckets and equipment, and preventing nose-to-nose contact between horses.
