Bill is absolutely right - EHD is why transplanted deer from northern states don't make it here in La.- they just don't have the natural resistance. Typically, wet ormoist areas have higher cases of EHD. Some infections are worse than others, with some deer showing no symptoms at all, and others dying a horrible death. Even so, we have hadsevereoutbreaks of EHD here, and have even identified a new strain on one of our southernmost WMA's.
