内罗毕羊病病毒是由尾粘蜱（R. appendiculatus）在不同龄期（阶段）摄食免疫、易感或非易感宿主后跨地传播的。垂直感染系列的蜱虫在成年期以免疫羊为食的幼虫和若虫能够传播病毒。病毒的跨卵巢传播似乎依赖于成虫期的传染性饲料。在产卵第4天之前，卵未发生明显感染。
Nairobi sheep disease virus was transmitted trans-stadially by the Ixodid tick, R. appendiculatus, after feeding of different instars (stages) upon immune, susceptible or non-susceptible hosts. Ticks in a vertically infected series were able to transmit the virus at the adult stage after feeding as larvae and nymphs upon immune sheep. Transovarian transmission of the virus appeared to be dependent upon an infective feed at the adult stage. Patent infection in eggs could not be demonstrated before the 4th day of oviposition.
