Epizootic Hemorrhagic Disease (EHD)

In 2013, Epizootic Hemorrhagic Disease (EHD) has been diagnosed in 7 deer in 6 counties. The laboratory confirmed deer are from Muskegon, Ottawa, Oceana, Ionia, Berrien, and Allegan counties. Small numbers of additional dead deer were reported associated with these mortalities. Total mortality estimates at this point are difficult to determine; final figures will be determined following the completion of the firearm deer season. It appears that the estimate will likely be in the 100 to 400 https://www.wc4eb.org/what/disease/epizootic-hemorrhagic-disease-ehd/deer range.

  • Deer in Genesee County tests positive for EHD, MI DNR News, Sept 20, 2017The Michigan Department of Natural Resources Wildlife Disease Laboratory and the Michigan State University Veterinary Diagnostic Laboratory today announced they have confirmed that a free-ranging white-tailed deer in Genesee County has died from epizootic hemorrhagic disease. EHD is a viral disease, sometimes fatal, found in wild ruminants such as white-tailed deer, mule deer and elk. There is no known effective treatment for, or control of, EHD in wild populations. The disease has been seen for decades in many areas of the United States.

  • Deadly Deer Disease Hits Kentucky, Lex18.com,July 31, 2017A deadly deer disease is hitting the population of wildlife in eastern Kentucky. Epizootic hemorrhagic disease, also known as EHD or “Blue Tongue” is spreading in multiple counties. Reports of dead deer are being called in to fish and wildlife officials across the state.
  • More than 2,000 deer reported dead in S.D. disease outbreak , Capital Journal, Nov 29, 2016Epizootic Hemorrhagic Disease, a viral disease that killed more than 3,700 deer in 2012, has impacted the population this year, with more than 2,000 deer found dead in 23 counties, The Mitchell Daily Republic reported.
  • After 2-year break, DNR finds a deer dead of EHD virus, Detroit Free Press, Sept 29, 2016 A deer in southwestern Michigan has died from a disease that killed more than 12,000 in the state in 2012.
  • Single deer in Berrien County tests positive for EHD, MI DNR News, Sept 29, 2016The Michigan Department of Natural Resources Wildlife Disease Lab and the Michigan State University Diagnostic Center for Population and Animal Health today announced they have confirmed that a deer in Berrien County has died from epizootic hemorrhagic disease (EHD), a sometimes-fatal viral disease found in wild ruminants. Deer deaths from EHD in Michigan have occurred sporadically since 2006. Prior to 2006, EHD outbreaks in Michigan occurred in 1955 and 1974. The estimated mortality has varied from 50 to 1,000 deer per year in the affected isolated areas. In 2012 the largest die-off occurred, with an estimated loss of over 12,000 deer. No cases of EHD were confirmed in the state in either 2014 or 2015.
  • Warm, dry weather can trigger wildlife diseases, MI DNR Bulletin, Sept 2016Given this summer’s hot and dry weather in many parts of the state, staff at the Michigan Department of Natural Resources Wildlife Disease Laboratory in Lansing has been looking at wildlife diseases affecting deer and waterfowl. “Due to the prolonged, dry, hot weather this year, we would not be surprised to see EHD emerge,” said Tom Cooley, DNR wildlife biologist and pathologist. “Mortality numbers depend on the strain of the virus, and how widespread the disease is – die-offs usually occur within one watershed area. If multiple watersheds are involved, the total mortality is higher.”
  • Viral disease killing hundreds of deer in the region, Spokesman-Review, Oct 2, 2015A drought-stoked outbreak of viral disease first detected in August is killing hundreds of deer from the Colville area south to the Lewiston region, wildlife biologists from Washington and Idaho say. At least 68 whitetails dead from bluetongue have been collected in the town of Colville, Terry LeCaire, manager of the city’s streets department, said Friday.

    Bluetongue has killed mostly white-tailed deer, but in recent weeks the disease also has been confirmed in some dead mule deer.
  • Scattered EHD Outbreaks Reported in 2015, QDMA, Sept 21, 2015Hemorrhagic disease (the collective name for EHD and bluetongue) pops up every year in late summer and early fall, usually during hot, dry weather when conditions are good for the tiny flying insects that spread the virus from deer to deer. Deer congregate to drink at the few available water sources, where the biting midges also reproduce and swarm. Symptoms include high fever and thirst, so sick and dead deer are often found in or near bodies of water.
  • Deer disease keeps worsening in Wisconsin, as predicted, WisconsinWatch.org, March 21, 2015More alarming still, the disease rate among adult male deer has reached 40 percent in north-central Iowa County and around 25 percent in two other sectors. And CWD is no longer found only in southern Wisconsin.
  • Down firearm deer hunting season expected for Southwest Michigan as herd recovers from EHD, MLive, Nov. 10, 2014Hunters in Southwest Michigan may see more deer during the Nov. 15-30 firearm season than last year, but the deer herd is still down significantly from previous years as it recovers from disease outbreaks that ravaged the population in 2012.
  • Insect-spread deer disease found in Muskegon Co., Michigan Radio, Sept 9, 2013The DNR says infected deer can suffer extensive internal bleeding, lose their appetite and fear of humans, grow weaker, salivate excessively and lose consciousness. It says sick or dying deer often are found along or in bodies of water.

  • ‘Don’t Veer for Deer’ – Though It May Be a Disease that Puts the Animals in Jeopardy, Rochester-Rochester Hills Patch, October 24, 2012The Michigan DNR is reporting that the deer disease EHD is back in the state this year, and it’s hit Oakland County.
  • Connections found between wetland cover, transmission rates of hemorrhagic disease in white-tailed deer, University of Georgia, Odum School of Ecology, July 2013They found in counties where wetland acreage increased from 1992 to 2001, reports of illness also increased. Where wetlands decreased, reports of illness decreased as well. Park explained this might be due in part to the habitat needs of biting midges that transmit hemorrhagic disease viruses. “They like to lay their eggs in wet mud habitats, areas like pond edges and bogs,” he said.
    But when it came to deaths from hemorrhagic disease, it was a different story. The researchers found no relationship between increasing rates of death and increasing wetlands, or any other land cover type, for that matter.
