This is good news as it means that the vaccines and treatments being developed has a high chance of being effective against future outbreaks.

Professor Simon Lovell from the Faculty of Life Sciences explained that using data from every outbreak since 1976, and found was that whilst Ebola was mutating, the function of the virus has remained the same over the past four decades which really surprised us. Unfortunately this meant that the Ebola virus that had emerged now since the 1970s would very probably do so again.
However, Professor David Robertson said the findings could be seen as good news as it also meant that vaccines and treatments developed during this current outbreak had a high chance of being effective against future outbreaks, and could hopefully stop the virus from spreading at a much earlier stage then.
The study is published in the journal Virology.
