Abstract

Six disinfectant chemicals were tested individually for effectiveness against low pathogenic avian influenza virus (LPAIV) A/H7N2/Chick/MinhMa/04. The tested agents included acetic acid (C2H4O2), citric acid (C6H8O7), calcium hypochlorite (Ca(ClO)2), sodium hypochlorite (NaOCl), a powdered laundry detergent with peroxygen (bleach), and a commercially available iodine/acid disinfectant. Four of the six chemicals, including acetic acid (5%), citric acid (1% and 3%), calcium hypochlorite (750 ppm), and sodium hypochlorite (750 ppm) effectively inactivated LPAIV on hard and nonporous surfaces. The conventional laundry detergent was tested at multiple concentrations and found to be suitable for inactivating LPAIV on hard and nonporous surfaces at 6 g/L. Only citric acid and commercially available iodine/acid disinfectant were found to be effective at inactivating LPAIV on both porous and nonporous surfaces.

摘要

对六种消毒化学品分别进行了测试，以检测其对低致病性禽流感病毒（LPAIV）A/H7N2/Chick/MinhMa/04的有效性。测试的药剂包括乙酸（C2H4O2）、柠檬酸（C6H8O7）、次氯酸钙（Ca(ClO)2）、次氯酸钠（NaOCl）、一种含过氧物的粉状洗衣粉（漂白剂）和一种市售碘/酸消毒剂。六种化学品中的四种，包括乙酸（5%）、柠檬酸（1%和3%）、次氯酸钙（750 ppm）和次氯酸钠（750 ppm），能有效灭活硬质无孔表面上的LPAIV。对传统洗衣粉进行了多种浓度测试，发现其在6 g/L时适用于灭活硬质无孔表面上的LPAIV。仅发现柠檬酸和市售碘/酸消毒剂在多孔表面和无孔表面上均能有效灭活LPAIV。
