A disease that's often fatal to white-tailed deer has been found in deer in Millcreek Twp., the Pennsylvania Game Commission said.

It is called EHD, or Epizootic Hemorrhagic Disease. It is spread to deer when they are bitten by infected midges.

Infected deer typically develop symptoms about a week after infection and die soon after, the commission said.

Symptoms include swelling of the face and neck, weakness and respiratory distress. 

The disease typically emerges in late summer and continues until midges die in the first hard frost of the season.

It is one of two viruses spread by biting midges that cause hemorrhagic disease.

The public is encouraged to report sick or dead deer, especially if several are found dead in the same area, the commission said.

They can be contacted at 1-833-PGC-WILD (1-833-742-9453).
