Abstract

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.

2020-2022 年柬埔寨猪价值链中甲型猪流感病毒的传播情况
我们分析了来自柬埔寨屠宰场的 4,000 份猪样本,发现来自商业农场的猪的甲型流感血清阳性率(40.0%)和流行率(1.5%)均高于小农农场(血清阳性率为 8.9%;流行率为 0.6%)。多变量分析显示,有证据表明猪只离开农场后会传播流感。研究结果对新兴畜牧系统的流感风险和监测具有重要意义。

期刊介绍: Emerging Infectious Diseases is a monthly open access journal published by the Centers for Disease Control and Prevention. The primary goal of this peer-reviewed journal is to advance the global recognition of both new and reemerging infectious diseases, while also enhancing our understanding of the underlying factors that contribute to disease emergence, prevention, and elimination. Targeted towards professionals in the field of infectious diseases and related sciences, the journal encourages diverse contributions from experts in academic research, industry, clinical practice, public health, as well as specialists in economics, social sciences, and other relevant disciplines. By fostering a collaborative approach, Emerging Infectious Diseases aims to facilitate interdisciplinary dialogue and address the multifaceted challenges posed by infectious diseases.
