why do we get sick in the winter? - part 2

Back in March 2008 I did a post when some new research came out on this topic. The news then was that there is a reason why the flu virus survives and transmits better in cold weather. It had been all about the temperature then.

Well, today's news suggests there may be more to the story...

The new twist is that there is a strong correlation between the absolute humidity of the air and the transmission and survivability of the flu virus. Absolute humidity is the measure of the total amount of water (vapor) in the air, and this is significantly more in summer's warmer air than in winter's cold air.

This finding is just one of correlation. There doesn't seem to be any theory or explanation for why this is so. In that sense, we may have to take this with a pinch of salt.
