We analyzed >4,000 pig samples from slaughterhouses in Cambodia and found higher influenza A seroprevalence (40.0%) and prevalence (1.5%) among pigs from commercial farms than smallholder farms (seroprevalence 8.9%; prevalence 0.6%). Multivariable analyses revealed evidence of transmission after leaving farms. Findings have implications for influenza risk and surveillance in emerging livestock systems.
我们分析了来自柬埔寨屠宰场的 >4000 个猪样本，发现商业农场的猪比小农农场的猪具有更高的流感 A 血清阳性率（40.0%）和阳性率（1.5%）（血清阳性率 8.9%；阳性率 0.6%）。多变量分析显示了离开农场后传播的证据。这些发现对新兴畜牧业系统中的流感风险和监测具有重要意义。
