2008年までに鳥インフルエンザH5N1に世界で393人感染し248人が亡くなられている

１月６日のエントリーで、中国・北京で鳥インフルエンザA/H5N1亜型の人への感染が確認されたことを書いたのだけど、そのことがWHOがらも報じられました。併せて、ベトナムでも感染があったことを報じています。

2008年の報告がまだWHOからあるのかもしれないけれど、2003年から2008年までにH5N1に393人が感染し、248人が亡くなられました。致死率は、国によって相当バラツキがありますが、全体では63％と非常に高率です。

とりあえず、2006年をピークに感染者数も死亡者数も減少していますが、今年はどんな状況になるのだろう。
