Vogelgrippe

Zitat:Erich posteteder Virus war inzwischen über Jahrzehnte unbemerkt in der Umwelt, nur jetzt wo jeder Vogelkadaver untersucht wird (hat man früher nicht gemacht), findet man einige Opfer, übrigends auch bei mir um die Ecke
Vielleicht solltest du dann nicht mehr hier posten - wegen der Ansteckungsgefahr :hand:

Der nun folgende Artikel hat in seinem Hauptfokus nicht direkt mit dem Thema Vogelgrippe zu tun, aber zeigt gewisse Risiken, Querverweise und mögliche genetische Entwicklungen bei Grippeviren auf, die uns in naher oder mittlerer Zukunft extrem gefährlich werden können.

Zitat:Flu Found Resistant to Main Antiviral Drug

Virtually all the flu in the United States this season is resistant to the leading antiviral drug Tamiflu, and scientists and health officials are trying to figure out why.

The problem is not yet a public health crisis because this is a below-average flu season so far and the chief strain circulating is still susceptible to other drugs — but infectious disease specialists are nonetheless worried.
(...)
Dr. Niman said he worried about two aspects of the new resistance to Tamiflu. Preliminary data out of Norway, he said, suggested that the new strain was more likely to cause pneumonia.

Flu typically kills about 36,000 Americans a year, the C.D.C. estimates, most of them elderly, very young or with problems like asthma or heart disease, and pneumonia is usually the fatal complication.

And while seasonal flu is relatively mild, the Tamiflu resistance could transfer onto H5N1 bird flu circulating in Asia and Egypt, which has killed millions of birds and about 250 people since 2003. Although H5N1 has not turned into a pandemic strain, as many experts recently feared it would, it still could — and Tamiflu resistance in that case would be a disaster.

Ich weiß, das unterstellt eine gewisse negative, pessimistische Sicht der Dinge. Die Mutation muss nicht überspringen. Aber bei dem Ausmaß an potenzieller genetischer Evolution, die Millionen an Generationen von Viren in wenigen Jahren hervorbringen können, scheint unser glimpfliches Davonkommen wirklich nur dem Zufall und unserem bisherigen Glück geschuldet zu sein.

Im übrigen: In China gab es wieder einen Todesfall durch Vogelgrippe.
