DEEP DIVE: FEVER PROTOCOLS & WHEN TO ISOLATE
An unexplained fever warrants immediate isolation precautions while you contact your veterinarian. Do not wait for coughing, nasal discharge, diarrhea, or a positive test.
For an adult horse at rest, over 101.5°F is a practical threshold for taking action.
WHAT IS A FEVER PROTOCOL?
A fever protocol is a planned response to an elevated temperature: identify and record the fever, separate the horse, notify your veterinarian and barn manager, and begin monitoring and infection control measures.
The goal is to evaluate the affected horse while limiting potential exposure to others. Not every fever is contagious, but the cause may not be apparent initially.
WHAT SHOULD YOU DO?
• STOP exercise and prevent contact with other horses. Use a designated isolation area; an adjacent stall may not provide adequate separation.
• CALL your veterinarian with the temperature, symptoms, recent travel, and possible exposure to sick horses. Call ahead before transporting to a hospital.
• ASSIGN separate buckets, a thermometer, grooming tools, and manure equipment. Limit caregivers. Handle healthy horses first, exposed horses next, and sick horses last.
• WASH hands and change protective clothing and footwear appropriately. Remove manure and debris before disinfecting; follow product instructions.
• RECORD temperature, appetite, water intake, manure, behavior, and medications. Follow your veterinarian’s monitoring schedule for affected and exposed horses.
• ASK before giving Banamine or bute; these medications can mask fever.
Know your horse’s normal resting temperature. Take routine readings after cooling out from exercise. Concerning symptoms require attention even below 101.5°F.
WHEN IS IT URGENT?
Difficulty breathing, staggering, inability to stand, severe diarrhea, significant colic, or rapid deterioration require immediate veterinary attention.
WHEN CAN ISOLATION END?
A normal temperature does not mean a horse is no longer contagious. Your veterinarian determines when release is appropriate and whether testing is needed.
