Dr. Mike: Flu season gets an early start

Flu activity started early this year, with cases first concentrated in Western states, including California and Washington. Dr. Mike Cirigliano says the circulating strain is H1N1 and urges people to get vaccinated to help protect themselves and those at higher risk. He also explains that mild, short-lived side effects can be mistaken for flu symptoms; the CDC says flu vaccines do not cause flu illness.
