Bethesda, Maryland–(ENEWSPF)–March 27, 2015. The Ebola virus circulating in humans in West Africa is undergoing relatively few mutations, none of which suggest that it is becoming more severe or transmissible, according to a National Institutes of Health study in Science. The study compares virus sequencing data from samples taken from patients in Guinea (March 2014), Sierra Leone (June 2014) and Mali (November 2014).
