The Pennsylvania Sate Game Commission is monitoring a viral disease that has killed over 1,000 deer in South Western Pennsylvania. Epizootic Hemorrhagic Disease or EHD is spread by small flies to deer, but not to humans or other animals. EHD has been found in most southern Counties and as far north as Butler, Armstrong and Lawrence Counties. Signs of the illness in deer start about seven days after exposure and deer will lose their appetite and fear of humans. Deer that die from EHD are frequently found near water. This past weekend 23 deer were found dead in Armstrong County.
