From the text:
It seemed pretty clear that the Marburg virus did not naturally circulate in monkeys, because it killed them so fast it could not successfully establish itself in them as a useful host. Therefore, Marburg lived in some other kind of host— an insect? a rat? a spider? a reptile? Where, exactly, had the monkeys been trapped? That place would be the hiding place of the virus.
