Study Links Ethiopian Marburg Outbreak to Animal-to-Human Spillover

Researchers from McMaster University, publishing in Nature Microbiology, have traced a recent fatal Marburg virus outbreak in Ethiopia to a single animal-to-human spillover event. The study found minimal genetic variation in virus samples, indicating rapid human-to-human transmission followed the initial jump. Marburg virus is highly dangerous, often exceeding Ebola's mortality rates, highlighting the importance of understanding zoonotic origins for public health.
