The number of deer that have died in northern Cook County from a virus not typically found in the area has reached 100, while two new suspected cases have turned up in Kane County, forest preserve officials said Friday.

The 250 cases of epizootic hemorrhagic disease, or EHD, identified in 32 Illinois counties this summer are still a far cry from the nearly 2,000 infected animals reported statewide in 2007, the worst year on record, officials said. But it's relatively early in the season for EHD, which typically propagates from July through October.

The two deer believed to have died of EHD in Kane County were found separately in ponds on private property last week, one in a business park near the Jane Addams Memorial Tollway and Randall Road, the other in a wooded area near Illinois Highway 25 and Algonquin Road, according to the Illinois Department of Natural Resources.
