Ebola can remain in nervous system of recovered patients and relapse years later, study warns

The deadly Ebola virus can remain unnoticed in recovered patients’ nervous system, and relapse months or even years later to start a new outbreak, scientists warn in a new study.

Ebola is one of the deadliest viruses in history, capable of killing 90 per cent of infected people, and recurring outbreaks have so far claimed a total of over 28,000 lives.
