Early treatment makes all the difference in outcomes.

Potomac Horse Fever (PHF) is a disease that affects horses, usually during the summer and fall months. It is caused by a bacteria called Neorickettsia risticii, which horses can get by accidentally ingesting aquatic insects (like mayflies or caddisflies) that carry the bacteria. Horses living near rivers, streams, or irrigated pastures are at higher risk, especially if barn lights are left on at night which can attract these insects.
Signs of PHF can include high fever, diarrhea, loss of appetite, depression, colic, swelling of the legs or belly, and laminitis. PHF is not contagious between horses, but it can be very serious and require hospitalization in some cases. If you notice any of these symptoms, contact your veterinarian right away. You can also discuss vaccination protocols with your veterinarian if you live in a high-risk area.
