What is the influenza virus so dangerous?

What is the influenza virus is so dangerous that, like all influenza viruses, it is subjected to the process of antigenic drift. This is the site where mutations in the genetic material that causes small changes occur in the physical structure of the virus.

These small changes are what scientists frustrated attempts to create the final vaccine against influenza. Due to continuous changes in the protein particles in the outer layers of virus (the immune system, and specifically forVaccination) of new vaccines will always be needed to combat new versions of the virus.

Swine influenza is an example of such change. But what these changes and what parts of the virus that causes the damage, destroying normal healthy cells?

The name of the H1N1 swine influenza virus gives us a clue to the internal life of the virus. It represents the main functional proteins on their surface.

The 'H' stands for hemagglutinin, a protein that binds toswine influenza virus in the cell and injected the contents into it.

The "N" stands for neuraminidase, a number of specialized enzymes, the infected cells causes the formation of new virus released.

these aspects of the swine flu make all potentially very dangerous. Although the form that is currently in distribution could be relatively mild, it is still a change in the virulent strain in the months before winter. The fact that there is also a newDisease means that there is no vaccine for the virus present. So if there is more lethal, we have provided no protection against it than the generic antiviral drugs like Tamiflu and Relenza are available.

know the devastation that influenza viruses can cause the Spanish flu infected more than a third of the world and killed more than 50 million people.

We have no choice, but the influence of alarm over the spread of swine fever. It isdangerous because it is so changeable and that is why we must take very seriously.
