The association between highly pathogenic avian influenza (HPAI) subtype H5N1 outbreak risk in poultry in 161 Romanian villages (October 2005 to June 2006) and environmental and anthropogenic factors was investigated. Village outbreak risk was associated with a village being <5 km from a major road (odds ratio [OR] 5.27, 95% confidence interval [CI] 1.21-22.9) or a river/stream (OR 1.97, 95% CI 1.06-3.72). Outbreak risk in the first part of the epidemic was associated with a village being <5 km from a major road (OR 3.31, 95% CI 1.10-9.98) or a regularly flooded land area (OR 5.08, 95% CI 1.08-23.9); whereas outbreak risk in the second part of the epidemic was associated with a village being <5 km from a river/stream (OR 5.5, 95% CI 1.69-18.9). Results suggest that both environmental and anthropogenic factors influence the risk of HPAI subtype H5N1 outbreaks in village poultry populations.
对罗马尼亚161个村庄(2005年10月至2006年6月)家禽中高致病性禽流感(HPAI)H5N1亚型疫情爆发风险与环境及人为因素之间的关联进行了调查。村庄疫情爆发风险与距离主要道路小于5公里的村庄(优势比[OR]5.27,95%置信区间[CI]1.21 - 22.9)或河流/溪流(OR 1.97,95% CI 1.06 - 3.72)有关。疫情第一阶段的爆发风险与距离主要道路小于5公里的村庄(OR 3.31,95% CI 1.10 - 9.98)或经常被洪水淹没的陆地区域(OR 5.08,95% CI 1.08 - 23.9)有关;而疫情第二阶段的爆发风险与距离河流/溪流小于5公里的村庄(OR 5.5,95% CI 1.69 - 18.9)有关。结果表明,环境和人为因素均会影响村庄家禽群体中HPAI H5N1亚型疫情的爆发风险。
