MADISON, Wis. (AP) -- A deer-killing disease is spreading in southern Wisconsin.
Wisconsin wildlife officials confirm that samples from deer found dead in Dane, Sauk and Waukesha counties have tested positive for epizootic hemorrhagic disease, or EHD.
Residents have contacted the Department of Natural Resources about seeing small groups of dead deer in southern Wisconsin. EHD is now confirmed in five Wisconsin counties -- Columbia, Rock, Sauk, Dane and Waukesha counties.
Additional tests of deer from Columbia, Iowa, Jefferson and Marquette counties are pending. Results are expected within the next couple of weeks.
EHD is transmitted by biting midges. The disease causes internal bleeding that can kill infected animals within a few days.
The last EHD observation in Wisconsin was in 2002 in Iowa County, where 14 deer died from the virus.
