Since 1967, cases of Marburg disease have been sporadic, primarily in remote regions, with recent outbreaks in Equatorial Guinea and Tanzania. Thus, it is not a new disease.
MVD spreads through direct contact with contaminated fluids or surfaces, primarily from infected bats or primates, enabling human-to-human transmission.
MVD symptoms emerge 2 to 21 days after exposure, resembling malaria with fever, fatigue, and joint pain. The virus progress to severe complications and multi-organ dysfunction.
MVD's average case fatality rate is 50%, with Rwanda's effective care achieving 23%. Symptoms vary, complicating diagnosis and leading to fatalities eight to nine days later.
Healthy individuals can face poor outcomes with MVD. But, supportive care improves survival, significantly lowering fatality rates in Rwanda.
