[Mod. PC氏解説: Since 2005,] Note by the OIE Animal Health Information Department 国際獣疫事務局 動物健康[衛生]情報部 : H5 and H7 avian influenza in its low pathogenic form in poultry is a notifiable disease as per Chapter 10.4. on avian influenza of the Terrestrial Animal Health Code (2010) 陸生動物衛生規約(2010年).
家禽の低病原性鳥インフルエンザ H5 および H7 も届出/公式報告 必要 [2005年から]。
[Mod. PC氏解説:
The reason these subtypes are reportable is that the H5 and H7 subtypes have the ability to modify their genetics and become highly pathogenic after continued transmission with the avian population. This additional OIE mandated reporting precaution gives us a more robust surveillance system for tracking the various subtypes of the influenza virus as they manifest in different ways. In 2008, Taiwan had a similar subclinical event and contained it without further spread and, more importantly, without evolution of the virus into its highly pathogenic form. ]
