A random effect meta-analysis was performed to estimate the worldwide pooled bovine viral diarrhoea virus (BVDV) prevalences of persistently infected (PI), viraemic (VI) and antibody-positive (AB) animals and herds. The meta-analysis covered 325 studies in 73 countries that determined the presence or absence of BVDV infections in cattle from 1961 to 2016. In total, 6.5 million animals and 310,548 herds were tested for BVDV infections in the global cattle population. The worldwide pooled PI prevalences at animal level ranged from low (≤0.8% Europe, North America, Australia), medium (>0.8% to 1.6% East Asia) to high (>1.6% West Asia). The PI and AB prevalences in Europe decreased over time, while BVDV prevalence increased in North America. The highest mean pooled PI prevalences at animal level were identified in countries that had failed to implement any BVDV control and/or eradication programmes (including vaccination). Our analysis emphasizes the need for more standardised epidemiological studies to support decision-makers implementing animal health policies for non-globally-regulated animal diseases.
采用随机效应荟萃分析估计了全世界牛病毒性腹泻病毒（BVDV）持续性感染（PI）、病毒血症（VI）和抗体阳性（AB）动物和畜群的流行率。荟萃分析涵盖了 1961 年至 2016 年期间来自 73 个国家的 325 项研究，这些研究确定了牛群中是否存在 BVDV 感染。在全球牛群中，共有 650 万头动物和 310548 个畜群接受了 BVDV 感染检测。动物水平的全球汇总 PI 流行率范围从低（≤0.8%，欧洲、北美、澳大利亚）到中（>0.8%至 1.6%，东亚）到高（>1.6%，西亚）。欧洲的 PI 和 AB 流行率随时间下降，而北美的 BVDV 流行率增加。在未实施任何 BVDV 控制和/或根除计划（包括疫苗接种）的国家，动物水平的平均汇总 PI 流行率最高。我们的分析强调需要进行更多标准化的流行病学研究，以支持决策者实施针对非全球监管动物疾病的动物健康政策。
