Swine Flu Mutation

In the article how a “Mild Flu May Turn Vicious” it explains how a flu similar to the swine flu could mutate. Possibly into a more virulent strain if it were to include two proteins known as PB1-F2 and NS-1. This action could greatly increase the virulence of the virus. The article goes on to explain how this is very unlikely to happen but it has occurred in the past. The example given was of when the Spanish influenza, which began as a mild, strain, and then mutated into a horrifically virulent strain, killing 20 million to 100 million people in 1918-19.
Our opinion of this possibility is it is a risk that health professionals should be cognascent of although the likely hood of it actually coming to fruition is low. The main problem as the article states is that these viruses are so unpredictable because it is how they react to old viruses in our cells that affect greatly how these flu’s can mutate.
