在问卷调查的基础上进行了一项横断面研究，以确定疙瘩性皮肤病（LSD）和相关危险因素在埃塞俄比亚三个主要农业气候带的分布。从分布在15个地区的44个农会共收集330份问卷调查。在不同的农业气候带中，中部农业气候带的牧群水平LSD患病率显著高于高地和低地农业气候带（55.2%[95%可信区间（CI） 47.5-62.6]）。总体观察到的动物水平LSD患病率为8.1% (95% CI 7.3-8.9)，观察到的死亡率为2.12% （95% CI 1.73-2.6）。中部地区与高地地区、低地与高地地区发生LSD的比值比（OR）分别为3.86 （95% CI 2.61-5.11）和4.85 （95% CI 2.59-7.1）。LSD发生的高风险与公共放牧和浇水管理（OR 4.1, 95% CI 2.02-6.18）和引入新牛（OR 8.5, 95% CI 6.0-11.0）相关。我们的研究结果描述了LSD在埃塞俄比亚不同农业气候中的分布以及相关的风险因素，并有助于阐明LSD在其他非洲国家的流行病学。
A cross-sectional study based on a questionnaire survey was conducted to determine the distribution of lumpy skin disease (LSD) and associated risk factors in three main agro-climatic zones of Ethiopia. A total of 330 questionnaire surveys were collected from 44 peasant associations (PA) distributed in 15 districts. Across agro-climate zones, herd-level LSD prevalence in the midland agro-climate was significantly higher 55.2% [ 95% confidence interval (CI) 47.5-62.6] than in highland and lowland agro-climate zones. Overall observed LSD prevalence at animal-level was 8.1% (95% CI 7.3-8.9) and observed mortality was 2.12% (95% CI 1.73-2.6). The odds ratio (OR) of LSD occurrence in midland vs. highland and lowland vs. highland zones was 3.86 (95% CI 2.61-5.11) and 4.85 (95% CI 2.59-7.1), respectively. Significantly high risk of LSD occurrence was associated with communal grazing and watering management (OR 4.1, 95% CI 2.02-6.18) and introduction of new cattle (OR 8.5, 95% CI 6.0-11.0). Our findings describe the distribution of LSD in different agro-climates in Ethiopia along with associated risk factors, and can help shed light on the epidemiology of LSD in other African countries suffering from the disease.
