A second western New York hospital is notifying patients that they may have been exposed to HIV, hepatitis B or hepatitis C through the improper sharing of insulin pens, hospital officials said Thursday. Olean General Hospital was mailing letters to 1,915 patients who received insulin at the hospital from November 2009 through last week, advising them to call to arrange for blood testing. The risk of infection is very low, hospital officials said, but they wanted patients to be aware of the possibility.
