Deadly disease detected in MN deer



ST. PAUL, Minn. (Valley News Live) – A disease that kills deer was first confirmed in Minnesota.

The Board of Animal Health Minnesota announced Wednesday the first cases of Epizootic Hemorrhagic Disease (EHS) in Minnesota Deer. Six out of seven animals in a small flock of captive whitetail deer in Goodhue County died of the disease earlier this month.

Animal health officials say the remaining dollar from this herd seems healthy at this time and shows no clinical signs associated with this disease. This is the first evidence of this disease in a Minnesota deer, but it is common throughout North America. It has been demonstrated in two Minnesota cows in Brown County (201

2) and Murray County (2013)

"This virus is transmitted between deer through biting mosquitoes or mosquitoes that are most active in the autumn before being killed by first frost of the season, "said Dr. Mackenzie Reberg, veterinarian of the Board of Animal Health. "These beetles can not travel far alone, and we are concerned about this discovery because the herd owner has not brought deer to the property for several years."

The swift and inexplicable deaths of the deer earlier this month alarmed the owner, who worked with their veterinarian, to deliver tissue from the carcasses to the Iowa State Veterinary Diagnostic Laboratory to determine the cause of death. EHD has been certified by the National Veterinary Services Laboratory of the USDA.

EHD affects members of the stag family, but there are no health risks to humans. Many different types of deer can be infected with EHD: Whitetail Deer are very susceptible and have a high mortality rate. Most die within 36 hours of clinical signs. These include fever, anorexia, lethargy, stiffness, shortness of breath, mouth ulcers and severe swelling of the head and neck.

There Is No Specific Treatment or Vaccination in the US

The Board has informed the Minnesota Department Natural Resources of confirmed cases in southeastern Minnesota.
