H1 N1

Recently, a study of 574 deaths by the National Institute of Health Surveillance, published August 20 suggests that parents whose age exceeds 50 years are relatively protected theH1 N1 influenza. On the other hand, these same people if they are less often affected are more likely to progress to a severe form.

Influenza A H1N1 is a disease (disease) transmitted infection after penetration of a new virus in the body. This virus is a mutant, ie the viral genome (viruses of all chromosomes) is composed of pieces of chromosomes from pigs, birds and humans. Another characteristic of this virus, which is different from the virus of seasonal influenza usually say is that it is mainly young and not the person concerned in case of immunodeficiency (who said that the deficit immune) to be infected by this disease.

What is the severity of influenza N1 H1? Influenza A H1N1 infected pigs is usually the first cousin of the human flu (influenza type H1 N1).
Typically, influenza virus, only with animals does not affect humans.
The virus is currently engaged Meanwhile, a mixture of pieces of chromosomes (called the genome) of other viruses not only swine, but also human beings and some birds, particularly the virus of bird flu. Until now it was thought that people with influenza A H1N1 swine professional. The main characteristic of this virus is swine flu can spread easily between humans.
It is important to note that pregnant women and obese people more H1 influenza N1 others.

The transmission from human to human is not known with precision, so the time is studied by a variety of laboratory infections in several countries around the world, particularly the United States, Canada (Laboratory Microbiology in Winnipeg), and Europe.
We know with near certainty that once the virus became human, he is more than pigs and the new virus must be known virus swine influenza viruses, but influenza A H1N1.
The virus has changed its name, is sometimes called the flu virus.
