H1N1 is not new virus?

H1N1 swine influenza gives great threats to human races nowadays. Its don’t have any cure yet. Believe me or not the H1N1 is not a new virus. How come?

Let have closer look on its structure. Its surface protein, hemagglutinin (HA) — which spikes cells and starts an infection— closely matches the HA in the H1N1 virus responsible for the 1918 pandemic. Separated by 91 years, the two strains of the highly mutable virus ought to be vastly different. This newfound similarity answers many mysteries about the 2009 pandemic, including why it largely spared the elderly.

The 1918’s virus evolved quickly in order to survive to different form of virus and lastly to be H1N1 virus that cause human pandemic.

Figure 1:  Descendants of the 1918 virus dodged antibodies by mutating (red) the tips of the HA to change shape and hold glycans, but the 2009 pandemic strain (far right) turned back the clock

This finding give scientist new way in curbing the next pandemic, so to make sure this not happen again, research on how the possibility of the virus mutate, and how they cause disease and how to cure it must be done. But I have bad feeling about these researches,   which will be underground research to build lethal bio-weapon, if human understanding the behavoiur of virus and how to create a new disease.
