Unusual ebola virus chain of transmission, Conakry, Guinea, 2014–2015

Abstract

In October 2015, a new case of Ebola virus disease in Guin­ea was detected. Case investigation, serology, and whole-genome sequencing indicated possible transmission of the virus from an Ebola virus disease survivor to another person and then to the case-patient reported here. This transmission chain over 11 months suggests slow Ebola virus evolution.
