The fatality rate is 24.1 per cent, below the average 50 per cent for Marburg cases. In most previous Marburg virus outbreaks, the death toll reached up to 88 per cent.

The ministry said that genomic sequencing of the Marburg virus indicated that the index case was linked to a zoonotic origin, meaning that the virus came from animal to human, without passing through multiple hosts.

The Marburg virus has affected mainly healthcare workers, who make up about 80 per cent of the cases.
