On Aug. 12, a 22-year-old Quarter Horse gelding in Benton County, Oregon, was confirmed positive for equine influenza by an attending veterinarian. He presented with left nostril discharge but did not have a fever, lethargy or coughing. The vaccinated gelding is reported to be recovering. One other horse at the private facility where he resides is also suspected of having equine influenza but has not tested positive. The facility is under voluntary quarantine.

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 humans’ contaminated hands, shoes, 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.
