Tick-borne viruses affecting sheep and goats can be be locally important diseases. Viruses of the tick-borne encephalitis complex occur across Europe to North-East Asia and are the cause of significant losses in small ruminant production. Thogoto virus which can be transmitted by Ixodid ticks has been associated with abortion storms in sheep, it may contribute to the large proportion of abortions which are due to unknown causes. Nairobi sheep disease is the most pathogenic virus disease known for sheep and goats in East Africa. Ganjam virus in India may ultimately be shown to be a significant cause of disease in small ruminants. Some unidentified Orbiviruses have been found both in ticks and sick sheep, and are thought to be a cause of some losses in African sheep and goats. Small ruminant populations in both Africa and Asia are vertebrate host for Congo-Crimean haemorrhagic fever, an important human pathogen, and for many Arboviruses some of which are of zoonotic importance.
影响绵羊和山羊的蜱传病毒可能是具有局部重要性的疾病。蜱传脑炎复合体病毒在欧洲至东北亚地区均有出现，是导致小反刍动物生产重大损失的原因。可通过硬蜱传播的托高托病毒与绵羊流产风暴有关，它可能是导致很大一部分不明原因流产的原因。内罗毕绵羊病是东非已知对绵羊和山羊致病性最强的病毒病。印度的甘贾姆病毒最终可能被证明是小反刍动物疾病的一个重要病因。在蜱和患病绵羊中均发现了一些未鉴定的环状病毒，它们被认为是非洲绵羊和山羊一些损失的原因。非洲和亚洲的小反刍动物种群都是刚果-克里米亚出血热（一种重要的人类病原体）以及许多虫媒病毒的脊椎动物宿主，其中一些虫媒病毒具有人畜共患病重要性。
