Flu-bug, Where are You?

Have you ever wondered why there is a flu season that coincides with our winter months?  National Institutes of Health researchers have discovered that the flu virus’s outer membrane hardens to a rubbery-like substance in colder temperatures.  This allows the virus to survive longer outside the body and be passed from person to person much more easily.

One scientist, Joshua Zimmerberg, PhD likened it to an M&M that melts in your mouth, but not in your hands.  If the temperature is too warm outside, the virus dies quickly, but in the cold it can transfer from one person to the next very easily.  Once inside the body, the coating melts, and it can infect the host’s cells, making him sick.
