Tanzania has pushed back against a report from the World Health Organization warning of a new Marburg virus outbreak in the country.

Tanzania's government said no-one in the country had tested positive for the Marburg virus after the World Health Organization (WHO) said at least eight people in the northwest were believed to have died from it.

With the fatality rate of 8% it is the same virus family as Ebola. The main carrier is from fruit bats which spreads to humans then through the contact of bodily fluids of infected individuals, it spreads to others.
