The Marburg virus, also known as the 'bleeding eye' virus, has killed 15 people in Rwanda.
The nickname "bleeding eye virus" comes from its symptoms, which in critical cases can cause bleeding from the eyes, nose, or mouth.
It is a highly infectious pathogen from the filovirus family, closely related to the Ebola virus.
It causes Marburg virus disease (MVD), a severe haemorrhagic fever with a high fatality rate, ranging from 24% to 88%.
This virus spreads through direct contact with the bodily fluids of infected individuals, contaminated surfaces, or materials like bedding and clothing.
