This is a list of human disease case fatality rates (CFRs). A CFR is the proportion of people diagnosed with a disease who die during the course of the disease (Cf. mortality rate). Data are based on optimally treated patients and exclude isolated cases or minor outbreaks, unless otherwise indicated.

Disease Treatment CFR Notes Reference(s)
Prion diseases, or transmissible spongiform encephalopathies (TSE) 100% Includes Creutzfeldt-Jakob disease and all its variants, Kuru, and Gerstmann-Staussler-Scheinker Syndrome. [1]

Plague — specifically the septicemic or pneumonic type Untreated ~ 100% [3]
Primary amoebic meningoencephalitis, Naegleria fowleri ~ 100% [1]
Rabies Untreated ~ 100% Preventable with vaccines but, once the symptoms manifest, the CFR is near 100%. [4]
