孟加拉国被认为是高致病性甲型H5N1禽流感（HPAI H5N1）流行的五个国家之一。南亚国家的活禽市场 (LBM) 由于其作为家禽交易中心的中心位置，被认为在 HPAI H5N1 和其他病毒的传播中发挥着重要作用。联合国粮食及农业组织（FAO）一直在促进改善孟加拉国的LBM生物安全。 2012年，我们招募了32个大型LBM（其中10个有粮农组织干预，22个没有援助），通过采用标准程序调查市场楼层、家禽摊位地板、家禽饲养病例和屠宰区以及基于问卷调查的整体生物安全情况，评估了所选LBM中的病毒传播情况。检查相对风险 (RR)，以比较干预和非干预 LBM 中 HPAI H5N1 的患病率。粮农组织干预的活体动物管理中采取的措施明显增多，其中包括将屠宰残留物保存在密闭容器中；对市场内的家禽运输工具进行消毒；防止乌鸦进入LBM，由市场委员会清洁市场/地板；湿法清洁；清洁后对地板/家禽栏进行消毒；市场上有充足的清洁水供应（P
Bangladesh has been considered as one of the five countries endemic with highly pathogenic avian influenza A subtype H5N1 (HPAI H5N1). Live-bird markets (LBMs) in south Asian countries are believed to play important roles in the transmission of HPAI H5N1 and others due to its central location as a hub of the poultry trading. Food and Agriculture Organization (FAO) of the United Nations has been promoting improved biosecurity in LBMs in Bangladesh. In 2012, by enrolling 32 large LBMs: 10 with FAO interventions and 22 without assistance, we assessed the virus circulation in the selected LBMs by applying standard procedures to investigate market floors, poultry stall floors, poultry-holding cases and slaughter areas and the overall biosecurity using a questionnaire-based survey. Relative risk (RR) was examined to compare the prevalence of HPAI H5N1 in the intervened and non-intervened LBMs. The measures practised in significantly more of the FAO-intervened LBMs included keeping of slaughter remnants in a closed container; decontamination of poultry vehicles at market place; prevention of crows' access to LBM, market/floor cleaning by market committee; wet cleaning; disinfection of floor/poultry stall after cleaning; and good supply of clean water at market (P
