Wisconsin officials have confirmed epizootic hemorrhagic disease (EHD) in non-lactating dairy cattle in Waukesha County, the first positive cattle tests in the state since 2013. The Wisconsin Department of Agriculture, Trade and Consumer Protection announced the test results Tuesday, Sept. 29. Wild and captive deer in Waukesha County have also tested positive for the virus. EHD spreads through bites from midges, sometimes called no-see-ums, and is most commonly found in late summer and early fall, when the insects are active. Cattle generally do not develop symptoms, unlike deer, according to the state agency. When cattle do show signs of illness, they may become lame or develop sores on their limbs, mouths or teats. Other possible signs include excessive salivation, fever and weight loss. Mouth, teat or hoof lesions are uncommon in cattle and can resemble signs of other foreign animal diseases, making veterinary testing important. The agency advises owners of cattle or farm-raised deer to contact a veterinarian if they notice symptoms. There is no cure for EHD, and officials said there is no evidence the disease affects people.
