Bovine viral diarrhea virus (BVDV) is an important pathogen belonging to the genus, family, which comprises viral species that causes an economic impact in animal production. Cattle are the natural host of BVDV and the main source of infection for pigs and other animal species. Due to its antigenic and genetic similarity with other important pestiviruses such as Classical Swine Fever Virus (CSFV), several studies have been conducted to elucidate the real role of this virus in piglets, sows, and boars, not only in the field but also in experimental infections, which will be discussed in this paper. Although BVDV does not pose a threat to pigs as it does to ruminants, the occurrence of clinical signs is variable and may depend on several factors. Therefore, this study presents a survey of data on BVDV infection in pigs, comparing information on prevalence in different countries and the results of experimental infections to understand this type of infection in pigs better.
牛病毒性腹泻病毒（BVDV）是一种重要的病原体，属于 科，该科包括引起动物生产经济影响的病毒种。牛是 BVDV 的天然宿主，也是猪和其他动物物种感染的主要来源。由于其与其他重要的瘟病毒如经典猪瘟病毒（CSFV）在抗原性和遗传上的相似性，已经进行了多项研究来阐明该病毒在仔猪、母猪和公猪中的真正作用，不仅在现场，而且在实验感染中，本文将对此进行讨论。尽管 BVDV 对猪没有像对反刍动物那样的威胁，但临床症状的发生是可变的，可能取决于几个因素。因此，本研究对猪 BVDV 感染的数据进行了调查，比较了不同国家的流行率和实验感染的结果，以更好地了解猪的这种感染。
