A comparison of the current swine flu outbreak to the annual seasonal flu shows many similarities and a few important differences. The many strains of the influenza virus produce the same symptoms and the same effects, as a general rule, but certain strains such as Swine Flu do behave slightly differently.
Seasonal influenza and the Swine Flu share a great many symptoms. They produce fever, lung congestion and cough, a stuffy or runny nose, body aches and extreme fatigue. Influenza is a “whole body” illness, unlike the common cold which affects the upper respiratory system alone.
