A new, preliminary genetic examination implies that the recent Ebola outbreak in Guinea may well have originated with a survivor of the 2014-2016 West African Ebola outbreak, alternatively than from an animal-to-human transmission.

According to the pre-print report, the outbreak probable started off with the survivor infecting a sexual spouse with the deadly virus as a result of semen — just after the virus lay dormant in the man for at minimum 5 years.
