At least six cases of influenza have been confirmed in the Pittsburgh region.
The flu is proving fatal, and putting people in the hospital. Not so much children and the elderly, but rather, middle-aged adults.
Pittsburgh hospital officials say an older woman with an underlying medical condition has died and eight others have been so seriously sickened by the H1N1 flu strain that they require machine assistance.
Flu activity is widespread across much of the country. And in the state of Pennsylvania, Allegheny County has the most cases.
