Man who survived Ebola five years ago may be source of Guinea outbreak

Finding raises questions about virus's ability to lurk long term in outwardly healthy bodies

An Ebola survivor is likely to have triggered the current outbreak in Guinea, scientists have said, in a shock discovery that means the virus may remain dormant for five years.

The finding, which comes after 29 cases and 13 deaths, raises fresh questions about the ability of Ebola to lurk in the body long term even while the survivor remains outwardly healthy.
