If they are such a reservoir, there is a strong likelihood they will carry the virus with them in subsequent migrations.
如果野鸟是这类寄主，它们将很有可能在随后的迁移行动中携带病毒。
Monkeys are susceptible to infection but are not considered viable reservoir hosts as virtually all infected animals die too rapidly to sustain survival of the virus.
猴子易受感染，但未被认为是可生存的有效储主，因为几乎所有受感染动物太快死亡以至于不能维持该病毒的生存。
Natural reservoir of the virus. Unknown.
病毒的自然宿主：未知。
Monkeys are susceptible to infection but are not considered plausible reservoir hosts as virtually all infected animals die too rapidly to sustain survival of the virus.
猴易感染这两种病毒，但不认为猴是可能的宿主，因为实际上所有感染这两种病毒的动物都迅速死亡，很难维持病毒的生存。
Unlike the case in domestic and wild birds, there is no evidence that domestic cats are a reservoir of the virus.
与家禽和野鸟的情况不同，没有证据表明家猫是病毒宿主。
The natural reservoir of the Ebola virus seems to reside in the rain forests of the African continent and in areas of the Western Pacific.

These animals act as the reservoir for the rabies virus and for its continued spread.
这些动物担当狂犬病毒的蓄水池并使他们继续传播。
This means that the virus does not copy itself, a capability key to forming what's called a reservoir.
这就表明病毒不能自身复制，而是具备了能够开启形成所谓存储池的能力。
Certain species of mosquitos are the reservoir of yellow fever virus; thus eradication of yellow fever is not feasible. This viral presence sometimes amplifies into regular epidemics.
