Deer Mortalities due to Epizootic Hemorrhagic Disease confirmed in South Dakota and New York

September 3, 2020: New York DEC Confirms Epizootic Hemorrhagic Disease (EHD) in Putnam and Orange County Deer

The EHD virus was first confirmed in New York in 2007 in Albany, Rensselaer, and Niagara counties, and in Rockland County in 2011.

EHD outbreaks occur sporadically in the northeast and deer in New York have no immunity to this virus. Consequently, most EHD-infected deer in New York are expected to die. In the north, the first hard frost kills the biting midge vectors that transmit the disease, ending the EHD outbreak. EHD is not spread from deer to deer.

“EHD has been confirmed by laboratory analysis in deer from Butte, Davison, Hughes, Meade and Sully counties. Additional reports of dead deer are coming in from other areas as well, many of which likely succumbed to EHD.

Minor deer losses to EHD can occur in any given year in South Dakota, but weather and habitat conditions will dictate the severity of the disease.”
