Marburg virus disease, also known as Marburg hemorrhagic fever, is most commonly found in sub-Saharan Africa.
The disease, first discovered in 1967 after outbreaks in Germany and Serbia, is caused by the Marburg or Ravn virus, which are classified as orthomarburgviruses.
Orthomarburgviruses occur naturally in the Egyptian rosette bat. Cave-dwelling fruit bats, which make their home throughout Africa and the Middle East, can spread the disease to humans through their droppings.
Symptoms, which include fever, rash and heavy bleeding, can appear suddenly and worsen rapidly. There is no treatment for Marburg, and the infection often leads to serious illness or death.
How it spreads
