Avian influenza

You know, the influenza goes around every year in winter. Have you already been inoculated against it? If you already have done so, you are right. However, maybe you are not always safe. Because, unfortunately, new kinds of influenza viruses is becoming a social problem. I want to tell about one of them "Avian influenza".

What's "Avian influenza"? It is viruses mainly to be infected with birds and increase in their intestinal tracts. Infected waterfowls with it don't appear the symptoms. On the other hand, infected fowls with it often appear the symptoms because the viruses have strong poisons when they infect fowls. For example as their symptoms, subcutaneous hemorrhages of legs, bleeding of cockscombs or crib death.

As the route of infection, the viruses mostly mediate excrements and infect other birds. It is thought that Avian influenza doesn't infect easily from the bird to a person since birds and human beings species are different.

Then, why Avian influenza is so dangerous for human beings? The reason is that viruses often vary in RNA. In other words, there is a possibility that they infect human being. The problem is very serious. In fact, some people have been infected with them. However, fortunately, they can't infect a person to another person as yet.

If the spread of an infection happen, it is expected that many people will die from it. I hope that such bad situations don't happen.
