ST. PAUL, Minn. (AP) – Minnesota Board of Animal Health officials say the virus was confirmed in seven deer on a goodhue county farm and six have died. The virus, called epizootic hemorrhagic disease, or EHD, is caused by biting flies and causes rapid death from internal bleeding. No vaccine is available for infected animals.
State virus officials say there is no indication that the virus is present in the wild deer population. And, although it's been detected in Minnesota, it has been present in the Dakota, Wisconsin and Iowa.
