Until now, the swine flu appeared to be the result of an infection from a virus exchange virus between pigs and humans. Influenza A H1N1 that started in early 2009, leading the global pandemic (for now include all countries of the earth) of influenza A H1N1, is an infection by a new virus that is a combination of several viruses currently circulating, Parents flu (in connection with birds), swine (in connection with the pig) and human.

Patients suffering from swine influenza have exactly the same symptoms as ordinary flu (seasonal).

What are the symptoms of swine flu?

There, after an incubation period (period between infection with influenza A H1N1 and the onset of symptoms) from 24 to 48 hours:

• A rise in temperature up to 41°C.
• Pain above type muscle throughout the body and, as usual for the flu, mostly in the back.
• Pain in the throat associated with headache .
• A prostration (with extreme weakness) sometimes with severe fatigue but variable among individuals.
• Difficulty breathing, sometimes very important.
• A rather dry cough had also the characteristic of being profound.
• A very important nasal discharge.
• Diarrhea (rarely).
• Vomiting (rarely).
• A loss of appetite occur suddenly.

The evolution of influenza A H1N1 is variable among individuals. With the new virus, it is impossible to predict changes with certainty. Usually, influenza A H1N1 evolves favorably toward recovery in a week (sometimes more).

It is possible to attempt to identify the pathogen, that is to say, the causative agent or if you prefer the microbe, using a reaction of hemagglutination or indirect immunofluorescence.

Moreover, the demonstration of antibodies can be obtained by performing a hemagglutination inhibition and radial hemolysis.

All these techniques require a relatively long period to highlight the causative agent, namely the virus. The laboratories are working hard to try to finalize a new test quicker and used daily.
