Rare Ebola Strain With No Vaccine Linked to 87 Congo Deaths

A rare strain of Ebola with no approved vaccine or treatment circulated undetected for weeks in conflict-hit northeastern Democratic Republic of Congo before killing at least 87 people.

The first case developed symptoms on April 24, creating a four-week detection delay that enabled extensive uncontrolled community transmission, Africa Centres for Disease Control and Prevention Director-General Jean Kaseya said in an online briefing Saturday.
