Winter dysentery is a highly contagious disease of cattle seen most often during the winter months. In the course of an epidemiological study, the management, production, hygiene and previous diseases in 15 herds were characterized by 32 variables. Each herd was then visited twice a week for 8 weeks and 8 to 10 cows were clinically examined during each visit. Winter dysentery occurred in half of the herds during the survey. All data were analysed by classical statistical methods and by multivariate analysis. Mild or severe disease provoked nasal discharge and was associated with significant economic loss. Winter dysentery outbreaks appeared to be associated with small farms in which the area available per cow is either too small or too large, the presence of coronavirus in the faeces and variations in the temperature of the stable and of the drinking water.
冬季痢疾是一种牛的高度传染性疾病，最常出现在冬季。在一项流行病学研究过程中，15个牛群的管理、生产、卫生状况及既往疾病由32个变量进行描述。随后，每周对每个牛群进行两次访查，持续8周，每次访查对8至10头奶牛进行临床检查。在调查期间，一半的牛群发生了冬季痢疾。所有数据均采用经典统计方法和多变量分析进行分析。轻度或重度疾病会引发鼻涕，并伴有重大经济损失。冬季痢疾疫情似乎与小型农场有关，在这些农场中，每头奶牛的可用面积过小或过大、粪便中存在冠状病毒以及牛舍温度和饮用水温度的变化。
