Ever wonder why more people catch the flu in wintertime? Well you're not alone. The pesky flu virus is more stable in cold air that contains low levels of humidity, according to the study conducted at Mount Sinai School of Medicine in New York. And since the flu virus spreads through the air, unlike colds which are spread through direct contact, more people are likely to catch the flu bug during winter.

See the New York Times article for an interesting discussion of how modern researchers found clues to aid their study design in a paper published after the flu pandemic of 1918.
