Bluetongue & Epizootic Hemorrhagic Disease
If you have questions about this resource, contact the College of Veterinary Medicine.
Summary
Bluetongue (BT) and Epizootic Hemorrhagic Disease (EHD) are viral diseases spread by biting gnats that primarily affect sheep, cattle, and white‑tailed deer, most often in late summer and early fall. BT is severe in sheep and can cause reproductive losses in cattle, while EHD is highly contagious and often fatal in deer but uncommon and mild in cattle. The viruses are not directly contagious and spread only through insect bites. Diagnosis is confirmed by blood testing, and there is no specific treatment beyond supportive care. Prevention focuses on gnat control, reducing standing water, and minimizing blood transfer between animals through proper management practices.
