New York State Department of Environmental Conservation has confirmed epizootic hemorrhagic disease (EHD) in two white-tailed deer from Putnam county and four white-tailed deer in Orange county. Please contact the DEC to report sick or dead deer, particularly if there is more than one deer in an area or the deer is near water.
September 27, 2017 - more states reporting EHD
PA, OH, MD, MI, CT, WV, KY, TN, and Ontario are all reporting EHD. PA has confirmed both EHD subtypes 2 and 6 in the state. PA and DE are asking the public to be alert for the disease. Results are pending from North Carolina and Virginia; testing was conducted at the Southeast Cooperative Wildlife Disease Study.
August 18, 2017 - Requests for public to be on alert for the disease in PA and DE
This is the first case in domestic livestock so far this year. Jefferson Co. borders the little piece of WV that sticks up between OH and PA. PA has reported EHD in a white-tailed deer in Beaver Co., which is very close to Jefferson Co. OH.
EHD is a viral disease of white-tailed deer that is transmitted by the biting midge in the family Culicoides. EHD outbreaks are most common in the late summer and early fall when the midges are abundant. In the past week, Pennsylvania has confirmed a case of Epizootic Hemorrhagic Disease (EHD) in Beaver County and is investigating increased deer mortality in several additional areas. Ohio has also confirmed a case of EHD in wild deer this week in Lorain County and is investigating increased deer mortality in additional areas. EHD outbreaks occurred in New York in 2007 (Albany and Niagara Counties) and in 2011 in (Rockland County).
Cornell’s Animal Health Diagnostic Lab has PCR testing available for EHD confirmation. Contact the Cornell Wildlife Health Lab (email@example.com) for more information.
In deer, the symptoms of EHD include fever; small hemorrhages or bruises in the mouth and nose; and swelling of the head, neck, tongue, and lips. A deer infected with EHD may appear lame or dehydrated. An infected deer may die within 1-3 days after being bitten by the midge or the disease may progress more slowly over weeks or months. Frequently, infected deer will seek out water sources and carcasses are often found near water. Often, a large number of dead or sick deer are found in a limited area. There is no treatment and no means of prevention for EHD. The dead deer do not serve as a source of infection for other animals because the virus is not long lived in dead animals.
EHD does not infect humans, and generally causes mild or inapparent infections in domestic cattle and small ruminants. Another similar virus called Blue Tongue can also infect deer, which is very difficult to tell apart from EHD without laboratory testing.
