Viruses in Winter
Why do people get the flu in winter when the climate is
cold, and viruses don't survive well in the cold?
Viruses don't survive well outside the body. In winter, we are inside
together more and are in closer quarters and therefore they have less
distance to travel. Different viruses have different methods of moving
between hosts. Some ride on air droplets and or dust, some are transmitted
by your hands. In fact, research shows that this is the most common means of
transmission. So washing your hands often is a good preventive measure.
