Biologists have reported outbreaks of hemorrhagic disease among deer and antelope across the state, primarily affecting white-tailed deer.
According to Brian Wakeling, big game chief at Montana Fish, Wildlife & Parks, hemorrhagic disease is an umbrella term for two specific viruses: epizootic hemorrhagic disease (EHD) and blue-tongue disease.
These viruses are carried by midges found in damp areas and transmitted to animals through bites when they come to drink water.
The disease causes internal bleeding and has a rapid onset, typically within a couple of weeks, making it difficult for biologists to detect symptoms before it's too late.
This fall, clusters of white-tailed deer deaths have been reported along the Clark Fork River west of Missoula and around Frenchtown.
