What is the swine flu?
What is influenza H1N1?

More recently came a new influenza or flu which brought new dangers to our health. It is very important that we know about what swine influenza or swine flu so we can recognize its causes, symptoms, how it spreads and we can act quickly and avoid contracting it.

What is influenza H1N1?

• The H1N1 flu is a new influenza virus that is sickening people. This has two genes of influenza viruses that usually circulate among pigs in Europe and Asia, and avian genes, and human genes. Scientists call this virus “quadruple rearranged.

The vaccine protects effectively and, is safe, inactivated virus is similar to others with whom we have long experience. So now we can recommend its administration, but only some children, not all.

The decision whether to apply a medicine must be based on risk-benefit principle, or what is the same, that the protective effect outweighs the risk or side effects of the drug, in this case of the vaccine. Although this vaccine is safe and well tolerated, influenza A is too, because previously healthy children outweigh the illness usually within days and with few symptoms that are usually well tolerated well as fever, cough, runny nose, depression, some have headache , muscle pain, abdominal or throat.

The vaccine may also cause fever, muscle pain (more on the point of injection) and symptoms similar to influenza. Therefore, the irrigation-benefit ratio does not justify the application of the vaccine to healthy children, but those at risk for complicated influenza.

One of the mysteries to be solved since the emergence of new H1N1 virus was whether those who had already suffered a flu throughout their lives were immunized against this pathogen.

After much debate, a team of researchers at the La Jolla Institute for Allergy and Immunology (USA) has found the answer. Their research indicates H1N1 has similarities with some of the influenza viruses that have circulated over the past 20 years, so that those who have spent any flu are partly protected.

Previous infections of bird probably provide some immunity from the current pandemic of H1N1 influenza virus, according to a study by the Institute of Allergy and Immunology, La Jolla United States published in the journal Proceedings of the National Academy of the Sciences’ (PNAS).

These findings may help alleviate some concerns that the H1N1 virus is so different varieties of seasonal flu that no prior population immunity.

The scientists, led by Bjoern Peters, used the database to compare what Epitope immunity markers of H1N1 influenza virus could be similar to the surface markers of previous seasonal flu strains.
