The Influenza A virus spreads rapidly, affecting
mass numbers of people in short periods of time,
causing epidemics and pandemics to occur. Though the
spread of Influenza is extremely quick and efficient in
Canadian populations, this is not the case in some parts
of the world. The environment has a very large affect
on the spread of the Influenza A virus.
The Influenza A virus spreads quickly in cold, wet
climates/conditions, such as winter, for a number of
reasons, including a lack of vitamin D from sunshine to
aid in the production of bacteria/virus fighting proteins,
a lack of UVB radiation coming from the sun to kill the
virus while airborne, as well as the virus’ ability to
spread and reproduce in aquatic environments.
In conclusion, the Influenza A virus spreads quickly
in environments, with colder temperatures with small
amounts of vitamin D and UVB radiation reaching the
Earth’s surface through sunlight. The spread of
Influenza A would be much more tame in a location close to the equator, where these factors are negligible,
rather than somewhere with an environment similar to
