The Washington Animal Disease Diagnostic Laboratory at Washington State University has confirmed bluetongue virus (BTV) in 42 animals submitted from Washington and Idaho this fall.
Most of the samples submitted to WADDL were from white-tailed deer. Other affected species included cows, domestic sheep, bighorn sheep, mule deer and a yak.
The laboratory, part of the College of Veterinary Medicine, detected BTV in animals from Whitman, Spokane, Asotin, Garfield, Pend Oreille and Stevens counties in Washington, as well as Latah, Clearwater, Canyon and Nez Perce counties in Idaho. Samples from cattle and bighorn sheep submitted from Churchill and Mineral counties in Nevada were also confirmed to have BTV.
