In both Drosophila and mosquitoes, protection lasts for generations following a single maternal exposure to positive-sense single-stranded RNA viruses.
In tissue samples from rhesus macaques, researchers find the virus in the same immune-privileged sites where Ebola has been found to persist in humans.
