For the first time, scientist have solid evidence suggesting exactly why the flu is so common in winter.

A new animal study suggests that the influenza virus' success hinges on low relative humidity and cold temperatures. Such conditions keep the virus more stable and in the air longer than warm, humid conditions, scientists said. And apparently, the frosty weather's role is more important than that of the human body in helping the virus thrive.
