Sick horses are a lot like sick kids. Once one in the household catches a cold, it’s likely to spread through the entire family. When one horse shows signs of sickness, not only are they affected, but there is a risk that the virus can quickly spread to other horses in close proximity.

Influenza (flu) and herpes virus (rhino) are the most common respiratory viruses in horses. Their incidence is increased in horses that travel, due to the stress of transportation and showing, and can potentially be spread to neighboring horses in the trailer and back on the farm.

The good news: You can reduce your horse’s risk of contracting these contagious respiratory diseases. Doing the right thing for your horse means taking both preventative and proactive measures to reduce the transmission, severity and duration of disease, as well as identifying sick horses quickly to contain the spread of disease to other horses with biosecurity and quarantine measures.

Preventative actions
Ultimately, everyone’s goal is to keep your horse happy and healthy.

This starts by vaccinating your horse with Core EQ Innovator® for the five core diseases (WNV, EEE, WEE, tetanus and rabies) that every horse, everywhere may be exposed to regardless of their location, age, breed or discipline.

Next, the most common risk-based respiratory diseases are flu/rhino. Ask your veterinarian to administer Fluvac Innovator® EHV-4/1 at least 2 to 3 weeks prior to traveling. This will give you confidence that you are providing the protection your horse needs to help prevent respiratory illness from flu/rhino.

Routine vaccines are only the first step. Prevention also includes taking precautions to limit the spread of disease before leaving home, on-site and upon your return.

This checklist can help you create an outline for your barn’s biosecurity plan.

Before the trip

  • Ensure your horse’s vaccinations are up to date based on veterinarian recommendations.
  • Confirm venue health requirements (up-to-date vaccination records, Coggins test, health certificate, passport) with enough advanced notice to get appropriate documentation from your veterinarian.
  • Consider having your veterinarian run a Stablelab® SAA stall-side test to ensure there are no early indicators of infection prior to leaving.
  • Sanitize and pack individual water/feed buckets, tack and equipment for travel.
  • Pack thermometer and emergency kit.

At the show

  • Clean and disinfect the stall before unloading your horse.
  • Limit nose-to-nose and any close contact with other horses.
  • Ensure each horse has their own individual tack, equipment and gear.
  • Avoid shared water sources or buckets on-site.
  • Watch your horse’s behavior, eating/drinking, manure production daily.
  • Take your horse’s rectal temperature at least once daily (or as per venue requirements).
  • Consider having the on-site veterinarian run a Stablelab SAA stall-side test to give peace of mind that there are no signs of infection prior to competition and leaving for home.
  • Watch for any signs of coughing, sneezing or nasal discharge of any color. If noticed, contact the veterinarian right away.

Back home

  • Avoid comingling/turning out your horse with others who stayed home for 14 days.
  • Continue to take daily rectal temperature for 14 days.
  • Watch for signs of illness, behavior change, fever, runny nose, coughing or sneezing and separate from others immediately if symptoms appear.
  • Consider having your veterinarian run a Stablelab SAA within that 14-day time frame of returning home to ensure that there isn’t any underlying infection present.
  • Clean and disinfect your trailer and any tack, equipment or other items that went to the show.

Identifying which horses are sick, which have been exposed and which may potentially get sick is critical for herd management and potential isolation.

Proactive measures
Veterinarians can detect and measure infection in 10 minutes using Stablelab, a hand-held diagnostic blood test that measures and quantifies serum amyloid A (SAA). SAA is a major, acute-phase protein produced by the liver that is a reliable biomarker for inflammation due to infection.1 The SAA levels quickly and significantly increase in response to an infection.

SAA has been shown to be 30 times more sensitive than a thermometer in identifying subclinical infection, before your horse even starts showing signs2, giving your vet a head start on treatment.

Knowing a horse is sick before registering a fever provides critical time to implement a plan of action for monitoring, isolating and ultimately treating infected horses faster.

Set up for success
Don’t let a respiratory disease derail your riding and show season.
