Case-fatality Ratio (Giesecke, pp.11-12)

The term is used almost exclusively in infectious disease epidemiology, while people outside our field tend to use the term 'lethality' (or inversely the 'rate of survival', which has a more positive ring to it). They both mean the same thing, namely the proportion of people who will die of a certain disease out of those who contract it.
