The porcine flu is an infectious, respiratory illness, which affects the gluttons. The most well-known viruses are those of the type H1N1, the most frequent, although also they circulate other subtypes inside the genre “Influenzavirus A”, as H1N2, H3N1 and H3N2.

This illness, which takes place fundamentally in winter and in autumn, has a morbidity that is usually high in the pigs, and a mortality till now low between human beings, of the 1 to 4 per cent.

The biggest infection risk is suffered by the persons who are exhibited in a more intense way to this type of animals, - poultry and pigs - in case these carry some viral vine that is capable of infecting the human beings. Also, the viruses of the porcine flu can mutar in the state for him that they can be infected from person to person.

Therefore, this porcine flu joins the list of illnesses of animal origin that can be infected to the human beings, like the well-known avian flu or the Illness Espongiforme Bovina, called “mad cow disease”, without forgetting other illnesses that have forced to take sanitary measures as the foot-and-mouth disease and the blue language.

SPROUT OF PORCINE FLU IN HUMAN BEINGS

In the human beings punctual infections have been detected till now. In Europe, from 1958, 17 cases have been notified. In the United States, in 1976, it detected an infection sprout for virus of the porcine flu in recruits of a military field of New Jersey, by what it were supposed, although it was never discovered, that had contacted pigs. From this case, there was a wide transmission of the virus with more than 200 infections and 12 hospitalizations. En Estados Unidos, en 1976, detectó un brote de infección por virus de la gripe porcina en reclutas de un campo militar de Nueva Jersey, por lo que se supuso, aunque nunca se descubrió, que habían entrado en contacto con cerdos. A partir de este caso, hubo una amplia transmisión del virus con más de 200 infecciones y 12 hospitalizaciones.

This sprout of porcine flu began in the Oaxaca southern state, last April 1, but it did not come untied until Thursday night, when the Mexican Executive reported in a surprising way, the closing school and of the capital universities, before the fear of an epidemic of this animal flu.

It was this Friday when the World Organization of the Health (WHO) showed its worry for 60 deaths in Mexico, related supposedly to this infection, to which 7 more persons add them affect in the United States, of which, none had had contact with pigs. On Sunday the epidemic jumped from America to Europe, with Spain like main importer.

With regard to the possibility of pandemic, which also was contemplated it does not so much with the case of the avian flu, one does not discard that it could take place because the danger of contagion of this flu is in the air that is breathed, only it is necessary to have the sneeze or cough of an infected person so that it is contagious. Nevertheless, it depends on the virulence of the virus and of the immunity of the persons, so much how of the efficacy of the medicines of the common flu to eradicate this animal flu.

This way, although this flu needs the direct contact between the glutton and the human being to be contagious, the same does not happen from person to person, where the contagion takes place for air, or for example, if a person touches something that has the virus of the flu and then it takes the hands to the mouth or to the nose.

Nevertheless, the illness is not transmitted for consuming either pork or products derived from the pig, since this virus dies to temperatures superior to 70 degrees centigrade.

SYMPTOMS OF THE CONTAGION

The symptoms of the porcine flu he is persons they are similar to those of the common seasonal flu, the fever superior to 39 grades, which appears in a sudden way; the respiratory symptoms, like the cough, the sneezes and the rinorrea; the muscular pains and of you will articulate; the intense headache; the annoyance of the eyes; and general discomfort, between others. los dolores musculares y de las articulares; el dolor de cabeza intenso; la irritación de los ojos; y malestar general, entre otros.

To avoid the contagion of this animal flu, it is necessary to evade the direct contact with persons who have a respiratory infection, the high contact between persons, to sharing food and to carrying to extremes the care of the personal hygiene, as well as to avoid the places where there are many people, between other precautions. It is always necessary to visit the doctor of an immediate way if there appear some of the said symptoms.

To diagnose that the contagion exists, an obtained sample of the respiratory system is gathered, between the first 4 ó 5 days of infection, which is when it has more probabilities of infecting the virus. The children, and some persons, can spread the virus for 10 days or more.

The treatment will consist of the same measurements of support and of medicine as the common flu, as there are the antiviral oseltamivir and zanamivir, that were used to contain the avian flu, always under medical prescription.

THE AVIAN FLU AND THE CRAZY COWS

The illness of major gravity is the acquaintance like “the mad cow disease” that was diagnosed for the first time in 1985, in the United Kingdom. This is a degenerative illness of the central nervous system of the bovine ones, characterized by a series of alterations in the behavior that end with the death.

In November, of the year 2000, the first cases of networks were detected in Spain with this illness, specifically in Gallicia. Then, the borders closed to the import of cattle of reproduction of France and Ireland, together with which it was already maintaining with regard to the United Kingdom, Portugal and Switzerland.

The first person who died in Spain to cause not of the “crazy cows”, but of a variant of the illness of Creutzfeldt Jacob, was in June, 2005. The cases of the “crazy cows” have promoted since then until April, 2009 752. Chronologically, the two first ones were at the end of the year 2000; to length of 2001 other 82 were confirmed; in 2002, 127; in 2003, 167; 137 in 2004; in 2005, other 98; in 2006, 68; 39 in 2007; 25 in 2008; and 7 in 2009. Cronológicamente, los dos primeros fueron a finales del año 2000; a largo de 2001 se confirmaron otros 82; en 2002, 127; en 2003, 167; 137 en 2004; en 2005, otros 98; en 2006, 68; 39 en 2007; 25 en 2008; y 7 en 2009.

For his part, the avian flu is an infectious illness of the birds, of which there are not known fifteen subtypes of viruses of this flu that infect these animals.

According to the WHO, it is more worrying than these it is the vine H5N1, which affects also the persons. The contagion takes place for narrow contact with the sick animal, generally birds, although also it has been detected in pigs and felines.

In case of the avian flu, the first cases in human beings were detected in 1997 in Hong Kong, where the WHO confirmed this year 18 cases of the avian flu in persons, of whom 6 died.

The illness reappeared at the end of 2003 in South Korea and Vietnam and since then he has received from himself the life of at least 257 persons as the WHO, none of them in Spain, as a consequence of this illness.

Nevertheless, one year later, on July 7, 2006 dead opposing wild duck confirmed to itself the first case of avian flu (of the vine H5N1) in a somormujo in the Park of Salburua (Vitoria). Next, the National Committee of Veterinary Sanitary Alert reinforced the alertness opposite to the avian flu in the wetlands of the north and of the vale of the Ebro.
