free chlorine level – pool and spa
CDC勧告の遊離塩素レベル「プール 1-3 ppm (= mg/L) および 温泉 2–5 ppm」は鳥インフルエンザ avian influenza A (H5N1)ウイルスの消毒に十分であることが最近の研究で実証された。新型インフルエンザ2009 H1N1など他のインフルエンザウイルスにも同様の殺菌効果のようです。
・・・, recent studies have demonstrated that free chlorine levels recommended by CDC (1–3 parts per million [ppm or mg/L] for pools and 2–5 ppm for spas) are adequate to disinfect avian influenza A (H5N1) virus. It is likely that other influenza viruses such as 2009 H1N1 virus would also be similarly disinfected by chlorine.
