- case fatality ratio
- the number of fatalities from a specified disease in a given period per 100 episodes of the disease arising in the same period. Unless all such deaths occur rapidly after the onset of the disease (e.g. cholera) they are likely to be the outcome of episodes that started in an earlier period (hence the term 'ratio' rather than 'rate'. Comparison of the annual number of admissions and fatalities in a given hospital in respect of a specific disease is known as the hospital fatality ratio.
