djdtc - the CDC has listed that only 148 people have died from west nile in the whole USA. The current number of cases for IL is 654 with 38 deaths.
WNV is NOT transmitted from person-to-person, animal-to animal, or animal-to-person. Only an infected mosquito can transmit the virus.
So far from what I have seen is that there are no reports of WNV in deer so far.
