Rabies Tops Global List as Most Lethal Virus by Fatality Rate
A visualization ranks ten viruses by case fatality rate, led by rabies (nearly 100% fatal once symptoms appear) and including Lujo (80%), Nipah (40–75%), Hendra (57%), Ebola and Marburg (~50%), H5N1 (50%), Crimean-Congo hemorrhagic fever (10–40%), and MERS-CoV (36%). The list highlights that most deadly viruses originate in animals, with some causing highly lethal outbreaks even if infections are relatively rare.
