ehd happens just about everywhere theres deer during a drought year. this year it was goign to happen. some deer survive it. i have been told by my instructors when i was in college that you can look at the hoof of the deer and if there above average ridges in the hoof the deer has survived it.
as far as eating a sick deer or any other animal. NEVER. i have never shot a sick deer but i have shot waterfowl with rice breast and you couldnt pay me to eat it even tho some researcher deems it safe to eat. no thanks. ill pass. if a sick deer walks under me ill sit back down and let nature do its thing unless its showing signs of CWD then i will burn the tag and get the animal to the division or to USDA ASAP. usually by bow season you wont see EHD deer walking around due to the fall rains and the fresh supply of water they find. this disease hits deer quick. usually once they get sick the stay at water and bed down then die.
