Ebola’s Fast Evolution Questioned

(Nature) – The Ebola virus is evolving more slowly than was previously thought, contends a controversial new study of viral genomes from the current West African epidemic. The findings, published in Science on 26 March, allay concerns that the pathogen could become more difficult to control and thwart therapies and vaccines in development. But other experts say the paper’s focus on the pace at which Ebola virus is changing is misplaced; the more important issue is whether the virus has gained mutations that make it more transmissible or dangerous to humans.
