Ebola virus hasn't become deadlier since outbreak

A new analysis has shown that Ebola virus has not evolved to become deadlier, despite mutating, since its outbreak 40 years ago.

The surprising results of the University of Manchester research, demonstrates that the much higher death toll during the current outbreak, with the figure at nearly 10,500, wasn't due to mutations/evolution making the virus more deadly or more virulent.

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.
