2 Cass County deer diagnosed with viral disease

LANSING, Mich. (AP) - Michigan wildlife biologists say two deer in Cass County have been diagnosed with an often-fatal viral disease.

The deer tested positive for epizootic hemorrhagic disease, or EHD.

The Department of Natural Resources said Tuesday the disease is transmitted by a biting fly. It causes extensive bleeding. Infected deer lose their appetite and fear of humans, grow progressively weaker, develop a high fever and finally lose consciousness.

It's not believed that humans can get EHD.

DNR wildlife chief Russ Mason says there is no known way to treat or control the disease. Michigan has had several deer die-offs from EHD as far back as 1955. The latest covered six counties last year.

Mason says outbreaks are happening more frequently, possibly because climate change is driving the biting flies farther north.
