Studies reveal four genetic lineages in outbreak

Ebola is evolving, but not becoming deadlier.
Researchers analyzed the genetic blueprints of Ebola viruses in hundreds of blood samples from infected patients, comparing these data with each other and previously published Ebola genomes. This work revealed how the virus traveled and changed biologically in the first long-term Ebola epidemic on record. The findings may help inform future vaccine development and public health responses.
As the epidemic progressed, Ebola split into at least four genetic lineages. Mapping these lineages over time, the researchers confirmed that Ebola initially spread from
