Equine Influenza
As we move into the competition season, your horse will come into contact with many others, increasing the risk of infection and illness. We would like to provide you with some key facts about equine influenza to help you stay informed and keep your horse healthy.
What is Equine Influenza?
Equine influenza (or equine flu) is a highly contagious viral respiratory disease that
spreads quickly between horses. While it’s rarely fatal, it can seriously affect your horse’s health, comfort and performance and outbreaks still happen every year in the UK.
Spot the Signs Early
Know the warning signs of equine flu:
• High temperature (often over 38.5°C/101.3°F)
• Persistent cough
• Nasal discharge
• Lethargy
• Reduced appetite
Equine flu spreads fast through:
• Coughing and sneezing
• Nose to nose contact
• Shared buckets and grooming kits
• Clothing, hands and equipment
• Poorly ventilated stables
Small Hygiene Steps, Big Impact-Simple actions make a huge difference:
• Clean and disinfect equipment
• Don’t share buckets or tack
• Wash hands between horses
• Change clothing if handling sick horses
Vaccinating Still Matters
Vaccinating is the single most effective tool we have to reduce the severity and spread of equine influenza.
Even vaccinated horses can be affected, but symptoms are usually milder and outbreaks are easier to control. Biosecurity isn’t overkill — it’s essential.
Many disciplines have strict flu vaccination rules and it’s always the owner’s responsibility to stay compliant. Check your dates before events to avoid disappointment (or worse, risk).
