Abstract

Background: Bovine tuberculosis (bTB) is the most important animal health concern in Wales. Annual testing across all cattle herds in Wales commenced in 2010. In 2017, a new geographic division of Wales was conceived, with bespoke cattle controls and eradication milestones reflecting the geographical heterogeneity of bTB distribution.

Methods: This observational study uses descriptive analysis and Poisson regression modelling to analyse bTB surveillance data from all herds in Wales.

Results: Since 2010, there has been a significant decrease (p < 0.0001) in bTB incidence (8.6%‒6.3%) and plateauing prevalence across Wales. Conversely, there has been an increase in bTB incidence and prevalence in discrete areas. Recurrence and persistence remain important drivers of bTB infection. One of the sharpest declines in bTB incidence was observed in an intensive action area where enhanced cattle control and wildlife vaccination were implemented in an area of high bTB prevalence. Increased herd size, dairy herd type and herd location are important risk factors affecting the rate of bTB incidents in Wales.

Limitations: This study includes data from Wales only.

Conclusions: Improvements in trends of bTB occurred from 2010 to 2021, but the spatial variations described in this paper support the continued need for regionally adapted surveillance and control measures.

2010 年至 2021 年威尔士的牛结核病趋势。

背景：牛结核病 (bTB) 是威尔士最重要的动物健康问题。威尔士从 2010 年开始对所有牛群进行年度检测。2017 年，威尔士酝酿了新的地域划分，制定了专门的牛群控制和根除里程碑，以反映牛结核分布的地域异质性：这项观察性研究采用描述性分析和泊松回归模型分析威尔士所有牛群的牛结核监测数据：自 2010 年以来，威尔士的 bTB 发病率（8.6%-6.3%）显著下降（p < 0.0001），流行率趋于平稳。相反，在一些离散地区，牛结核发病率和流行率却有所上升。复发和持续存在仍然是导致牛结核感染的重要因素。黑死病发病率下降最快的地区之一是在一个强化行动区，该地区在黑死病高发区加强了牛群控制和野生动物疫苗接种。牛群规模扩大、牛群类型和牛群位置是影响威尔士牛结核病发病率的重要风险因素：本研究仅包括威尔士的数据：从 2010 年到 2021 年，牛结核病的趋势有所改善，但本文所述的空间差异表明，仍有必要采取适合地区特点的监测和控制措施。
