Public Health Moment

State health officials report that the flu is now widespread in Minnesota. While not all of the cases are the swine flu, or H1N1, officials believe it's playing a big role in the upsurge.

So, what are the symptoms? We asked John Finnegan, dean of the University of Minnesota School of Public Health.

He says the symptoms are similar to those of seasonal influenza - they include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills and fatigue. Some people have reported diarrhea and vomiting.

Finnegan also explains when someone should seek medical care.
