Wisconsin Confirms First Cattle EHD Case Since 2013

Wisconsin has confirmed epizootic hemorrhagic disease (EHD) in non-lactating dairy cattle in Waukesha County, the state’s first cattle detection since 2013, amid an outbreak affecting deer in several counties. Cattle usually show few or no signs, but the affected animals had lesions on their feet; other possible symptoms include lameness, fever, weight loss, excess salivation and sores. The virus spreads through biting midges, and new cases typically decline after the first significant frost; herd owners should consult a veterinarian about diagnosis and herd health. Officials say EHD does not infect people, and meat and milk from infected animals pose no known human health risk.
