Abstract

Evolution in the Ebola virus outbreak Has rapid mutation produced alarming new virus characteristics in the 2013–2015 Ebola virus outbreak in West Africa? Hoenen et al. sequenced isolates obtained 9 months into the epidemic from cases in Mali. The nucleotide substitution rate was consistent with rates estimated from past Central African outbreaks. In contrast, analysis of sequence data from early in the outbreak indicated rapid mutation. This more recent finding offers confidence that diagnostic methods, vaccines, and other treatment interventions will remain effective. Nevertheless, vigilance must be maintained: A few mutations can radically change the biological properties of other RNA viruses. Science , this issue p. 117
