WASHINGTON/VANCOUVER (dpa-AFX) – Deux Vogelgrippe-Fälle bei Kind et un Teenager in Nordamerika geben Wissenschaftlern Anlass zur Sorge. In the United States, there was a first infection with a type of Vogelgrippe H5N1 virus. Zum anderen entdeckten Fachleute die Vogelgrippe in einem canadischen Teenager. The virus in the heranwachsenden is mutiert and has been sich an den menschlichen Wirt angepasst, erklärten Virologen.

The Canadian teenager lived two women in a critical situation in a unique country house, like the Canadian government office. The media take care of it before the Jugendliche zuletzt weiter in Behandlung. Trotz der Anpassung du Virus gebe es keine Hinweise darauf, dass sich andere Menschen bei the Teenager Angesteckt hätten, berichtete mehrere mehrere Medien übereinstimmend.

Risk for all activities linked to the exploitation of natural resources

The US-American Kind, in its Kindertageseinrichtung in Kalifornien ging, zeigte nur leichte Symptom. All negative family tests are performed by the United States CDC. Mensch-zu-Mensch-Übertragungen wurden bislang weder in the USA noch in Kanada nachgewiesen. The authorities of the different Länder are faced with risks linked to all activities linked to the environment.

In any case where the official account is not yet available, the Ansteckung will pass through your request. The Vogelgrippe H5N1 is last in the Wildfires of the ganzen Welt weit verbreitet, also zahlreiche wildlebende Säugetiere infizierten sich. Außerdem führte das Virus jüngst zu Ausbrüchen in Geflügelbetrieben in Canada sowie in Milchbetrieben in the USA.

Mal bei Kühen infiziert, mal bei Vögeln

In the United States, there are 55 cases of H5N1 infection. If the Ausmaß is bigger, it will be left out. The most infected men are infected with dairy products, due to the virus in the United States under the kitchen herb. Die verläufe waren mild; However, if the Krankheit lasts for a Bindehautentzündung, weil the Virus wohl über die Augen in den Körper eintrat.

In Canada we have a specific virus in official offices that want the Jugendliche bei einem Vogelangesteckt hat. Auf Geflügelfarmen und bei Wildvögeln in der Region seien ähnliche Viren gefunden worden. As the Fachjournal “Nature” reported, specific mutations of the virus are possible, this H5N1 variant can be better infected with menstrual infections. The virus has been spread further among adolescents.

Virologist Jesse Bloom of the Fred Hutchinson Cancer Center, known as the American broadcaster CNN, who is one of the first to be informed by the Wissenschaft of this art of human mutations in the case of H5N1 . The three mutations discovered by Stellen are the virus which is the lightest, so that a menschliche Zellen attacks itself.

“Es gibt Grund zur Besorgnis”

The fact that there is no doubt, however, that a new pandemic is unavoidable, cited “Nature” by immunologist Scott Hensley of the University of Pennsylvania in Philadelphia. “Es gibt Grund zur Besorgnis,” he said. “Aber kein Grund, völlig auszuflippen.”

The whole world is at the beginning of the H5N1-Ausbruchs dem “Nature”-Bericht zufolge etwa 900 Infektionen in Menschen nachgewiesen wordsen. In the case of allergy sufferers, the men will contact you directly. Bloom told CNN: “Gluviruses have a high mutation rate. » When the virus is also a virus that was created by humans, it can pass to them later. “Es ist nicht sicher, aber möglich.”/scb/DP/he
