This paper reports the investigation of risk factors for bovine herpesvirus-1-seropositivity, based on a cluster-sample survey of the Belgian cattle population. This serosurvey was carried out in 1998 in 309 randomly selected unvaccinated herds of all types (dairy, mixed and beef) were all bovids (N = 11,284) were sampled. Older and male cattle had higher seroprevalence. Origin (homebred or purchased) and herd size interacted; for smaller herds (< or = 50 cattle on the premises), purchase status and larger herd size were risk factors, whereas these effects were not observed for larger herds.
本文报告了基于对比利时牛群的整群抽样调查，对牛疱疹病毒1型血清阳性危险因素的调查。这项血清学调查于1998年在309个随机选择的未接种疫苗的各类牛群（奶牛、混养和肉牛）中进行，所有牛科动物（N = 11284）均被采样。年龄较大的牛和公牛血清阳性率较高。来源（本地饲养或购买）和牛群规模存在相互作用；对于较小的牛群（场内牛数量≤50头），购买状态和较大的牛群规模是危险因素，而在较大的牛群中未观察到这些影响。
