The deadly Ebola virus could be mutating to become even more contagious, a leading U.S scientist has warned.
The disease has killed nearly 4,000 people, infecting in excess of 8,000 – the majority in the West African nations of Guinea, Sierra Leone and Liberia.
Communities lie in ruins, thousands of children have been orphaned, millions face starvation but the virus continues its unprecedented pace, invading and destroying vast swathes of these countries.
Meanwhile three nurses, two in the U.S. and one in Spain have caught the infection while treating Ebola patients, despite wearing protective suits.
Now U.S. scientist Peter Jahrling of the National Institute of Allergy and Infectious Disease believes the current Ebola outbreak may be caused by an infection that spreads more easily than it did before.
