What is the swine flu so dangerous?

What is the swine flu is so dangerous that, like all influenza viruses through the process of antigenic drift. This is when genetic mutations of the materials that occur slight changes in the composition of natural causes viruses.

These changes are light, attempts to tackle what scientists create the flu vaccine final. Due to constant changes in the protein particles of the outer layers of viruses (the immune system to the targeted during theVaccination), new vaccines are still needed to get new versions of the fight against the virus.

The swine flu is an example of such a change. But what these changes and what parts of the virus causing the damage, destroying normal cells healthy?

The name of H1N1 swine influenza gives us an indication of the inner workings of the virus. It represents the most important functional proteins on their surface.

The 'H' stands for hemagglutinin, which is a protein that bindsswine influenza virus in cell and injected its contents into it.

The "N" stands for neuraminidase, a number of specialized enzymes, which causes infected cells, the virus has recently released.

these aspects of swine flu makes all potentially very dangerous. Although the form that is currently distributed relatively mild, it could still change into a virulent strain in the months before the winter arrives. The fact that there is also a newDisease means that there is no vaccine against the virus present. So if it is more lethal, we do not protect against them, except those made under the general anti-viral drugs like Tamiflu and Relenza are available.

We know that influenza viruses to cause damage, Spanish flu has infected more than one third of world population and killed more than 50 million people.

We have no choice, pigs, vigilant as to the spread of the fever that is.dangerous because it is so changeable and that is why we must treat it very seriously.
