That doesn't include Davis county. The first place CWD was found in IA, on a deer farm in 2012.
Which is only one county away from this case in the wild. Maybe their only mapping wild cases.
Loosing battle. The deer farms claim wild deer gave it to their herd, the DNR's claim the opposite. I don't think anyone really knows. Double fencing is the least they could do to keep either from happening IMO.
