U.S. health officials say the strain of flu virus going around this year has been linked to more hospital admissions and deaths than in recent years. It's not to late to get a flu shot.

So what does a doctor do to avoid getting sick?

Dr. David Zich is with Northwestern Memorial Hospital.

(Zich) "I wash my hands well. Believe it or not, exercise increases your antibodies and your resistance to the flu. Make sure that you, you avoid people who are coughing and sneezing, as much as you can."

In most cases, flu can be treated at home with fever-reducing medication, rest and liquids. If you want the prescription drug Tamiflu to be an option, you have to start taking it within 48-hours of the first symptoms. It will cut about a day off of your recovery time.
