CHICAGO (AP) -- The head of the Illinois Department of Public Health says the state has logged nine probable cases of swine flu, all in northern Illinois.
Dr. Damon Arnold says five probable cases are in Chicago, while two are in Kane County and single cases are in both Lake and DuPage counties. The youngest person diagnosed is age 6. Two other cases are children and the rest are adults.
Arnold says all the cases so far have been mild and nobody has been hospitalized.
Arnold appeared at a news conference Wednesday called after Chicago closed an elementary school after one student there was found to have a probable case of swine flu.
Arnold, Chicago Mayor Richard Daley, Gov. Pat Quinn and other officials all said the state is working to prevent further illnesses.
