For fever in a foal, please refer to Equine Diarrhea/Septicemia, Neonatal Foal Acute Diarrhea Diagnostic Plan.

This diagnostic plan is designed to detect a broad spectrum of systemic bacterial, viral, and some blood parasite causes of acute fever, as well as certain inflammatory changes which may assist in detecting the underlying problems.

- Viral causes of illness are best detected during the first week of illness.
