Owning a horse is a wonderful experience. If you’re fortunate enough to have your own hooved companion, you’ve probably already experienced how precious a friendship with a horse can be. Horse ownership is not all whickering and magnificent moments, though. Horses are also extremely susceptible to illness and injury. One of the numerous things you should be on the alert for is equine influenza, sometimes known as horse flu. A local Lake Echo, NS equine veterinarian discusses some basic information on equine influenza below.
What is Equine Influenza?
Equine influenza, like the human flu, is a highly contagious respiratory disease. It affects horses and other equines, including donkeys and mules. It can also infect other animals, including dogs. The sickness is caused by two distinct influenza viruses. These two viruses, H7N7 and H3N8, are distinct from those that cause human and avian flu, yet they are linked.
Influenza A has various subtypes that can become zoonotic, or spread from one animal to another. If you’re curious about the names, the H stands for hemagglutinin and the N for neuraminidase. Both of these proteins can be located on the virus’s surface. There are 18 varieties of H subtypes and 11 N subtypes, totaling 198 potential combinations. Different strains can share genetic information. This is true for many of the more dangerous flus you’ve heard about, including swine flu and avian flu.
When Did Equine Influenza Begin?
Equine influenza is nothing new. Outbreaks have been reported throughout history. In fact, when horses were our primary mode of transportation, EI epidemics had a terrible impact on the economy. Today’s outbreaks primarily affect the horse industry, but they can still be quite dangerous.
How Does the Equine Flu Spread?
Equine influenza can be transferred both directly and indirectly. Unfortunately, horses can become contagious before exhibiting any symptoms.
The disease spreads through direct contact with sick animals, or through transmission via clothes, brushes, buckets, or tack. EI outbreaks are more likely in regions with a high concentration of horses, such as shows, races, and auctions. The more crowded a location, the greater the risk. Horses are also more vulnerable during transportation, particularly if they share a trailer or use one that has recently been occupied by an infected horse.
A few crucial points regarding transmission:
- Airborne droplets from coughing horses can carry the virus up to 150 feet.
- A single infected horse can transmit the flu over a whole barn.
- Horses can shed the virus for up to two weeks following infection.
- Many horses are immune to the virus, but they can still transmit it. That means that even if a horse appears to be in excellent health, he could contaminate the entire herd and stable.
- Transmission rates typically rise throughout the cold months.
One of the most worrying aspects of horse flu is its rapid spread. The virus normally takes one to five days to incubate. That speed enables rapid spread. This can be especially risky for events like exhibitions and races.
What Are the Clinical Signs of Equine Influenza?
Being a great horse owner is keeping a watchful look out for any signs of illness or injury. It’s critical to understand the clinical indications of horse flu. One of the most common causes is watery nasal discharge. Other symptoms include coughing, fatigue, loss of appetite, and weakness. Your horse may also have swollen lymph nodes.
Is There a Vaccine for Equine Influenza?
Fortunately, vaccinations are available. These immunizations are your primary weapon in the fight against equine influenza. Your veterinarian will be able to provide you detailed advice on the best vaccine and booster regimen. This will vary slightly. If your horse travels and/or shows frequently, he may require boosters every six months. A pregnant mare must be immunized before foaling.
How Is Equine Influenza Treated?
Horses who are healthy and have no difficulties can typically be managed with supportive care. Rest is quite important. The conventional guideline is to give Silver one day off for each day he has a fever.
Equine flu affects some horses more severely than others, just like it does in humans. If your horse’s fever exceeds 104 degrees Fahrenheit (40 degrees Celsius), your equine veterinarian may offer nonsteroidal anti-inflammatory drugs (NSAIDs) or, in certain situations, antibiotics. As usual, consult with your horse veterinarian before providing any medicine.
What Is The Prognosis For Horses With Equine Influenza?
Most horses recover within two to three weeks. However, while rare, horse flu can be lethal. It’s also crucial to note that certain horses will be extremely sensitive to subsequent illnesses while they heal. In general, take in mind that each horse’s recovery period may differ slightly. Horses who were seriously impacted may take up to 6 months to fully recover. Ask your equestrian veterinarian for particular guidance.
How Can I Protect My Horse from Equine Flu?
Preventing horse influenza is not an exact science. It’s also difficult to prevent in horses who interact with a variety of other horses, either directly or through stablemates. However, there are things you can take to mitigate the danger.
- Horses should be quarantined after being purchased or relocated to a new barn.
- Follow proper cleaning and hygiene practices. This applies not only to stalls, but also to tack and brushes.
- Don’t share your horse’s equipment with his stablemates. (Tip for boarders: use patterned duct tape to designate your items and prevent them from getting mixed up with other horses’.)
- Take extra precautions during epidemics and at events like shows.
- Always wash your hands before and after touching or grooming your horse.
Keep an eye out for the warning signs mentioned above. If you see any of these symptoms or anything else that appears to be wrong, please contact your equine veterinarian immediately.
