Actually we have learned a great deal more since WI's initial detection. We know now that fawn infection cannot be detected until mid to late January (based on normal fawn drop). Initially it was thought that the prions were detectable in the central nervous system and certain organs only...now it can also be detected in muscle tissue. They have data on transmission rate, and distance traveled including far flung sparks. We now understand much more about defense (actively reducing population) in a densely (deer) populated area for the first time. These are just a few examples, but I am certain the Iowa DNR is up to speed on the most current knowledge data base. Yes there is a lot yet to learn, and help and cooperation is really going to be needed from hunters and landowners.
