Hi Dave,
The conditions in Canada in the winter are actually probably more conducive to flu virus survival outside the body. The virus lasts longer at lower temperatures (and indefinitely below freezing) and lower levels of sunlight (less UV to damage it) and humidity. On a dry non-porous surface such as plastic or metal the virus may survive for several days. I believe studies have shown that on a dry piece of paper it remains viable for 15 minutes. If it is in mucous then it can survive much longer.
So even though it is relatively humid in BC during the winter it is still cold and we get little sunlight.
