Stomach upset and vomiting are more common in kids compared to adults.

Most patients recover from flu easily sans any severe complications, though family time, missing work, as well as other affected activities are reported. However, for some patients, flu may result in hospitalization cases and even death, based on the CDC reports.

You stay safe and keep others safe by taking a flu shot this season.
