In the Northern hemisphere, winter is the time for flu, but the exact timing and duration of flu seasons vary.
While seasonal flu outbreaks can happen as early as October, most of the time flu activity peaks between December and February, although activity can last as late as May.
February is the peak month of flu activity with the highest percentage of respiratory specimens testing positive for influenza virus infection. During a 32-year period, flu activity most often peaked in February, followed by December, January and then March.
Public health officials suggest we consider getting a flu shot and bowing, instead of shaking hands during this highly congestion flu period. Finally, remember to wash your hands as often as possible.
