Hi!
'Need some clarification here. Are you asking for the definition of each of these words or are you linking them to "incidence" or the incident rate?

For example, a fatality is a death or dead body.
A fatality rate is the noted death rate in a series of people effected by the same incident like a disaster, war or famine.

Incidence - the frequency with which something occurs. In medical terms, it usually refers to the statistical occurance of (e.g.) a disease within the general population, measured by how many cases there are per x thousand of the population generally.

Mortality - The ratio of the total number of deaths to the total population. Can also refer to the rate of death from a particular disease. e.g. SARS has almost 100% mortality.

Morbidity - diseased condition or state or the incidence of a disease or of all diseases in a population.

Fatality - condition, disease, or disaster ending in death.

difference between morbidity and mortality.
Mortality - deaths in a population. The mortality rate is normally the ratio of deaths to the sum of births in a given period.

Hi Guest,

Morbidity relates to illness

Morbidity - diseased condition or state, or the incidence of a disease or of all diseases in a population.

Mortality relates to death

Mortality - The ratio of the total number of deaths to the total population. Can also refer to the rate of death from a particular disease. e.g. SARS has almost 100% mortality.

Hi Abbie,
The ratio of the total number of deaths to the total population. Can also refer to the rate of death from a particular disease. e.g. SARS has almost 100% mortality.


If I'm not mistaken, mortality rate (as in infant mortality rate, maternal mortality rate) is calculated as the ratio of deaths to births (or births + deaths) in a given period (not always, but very often)
Mortality itself isn't a rate.

From Oxford Phrasal Verbs Dictionary for learners of English:
1 the state of being human and not living for ever: After her mother's death, she became acutely aware of her own mortality.
2 the number of deaths in a particular situation or period of time: the infant mortality rate (= the number of babies that die at or just after birth) Mortality from lung cancer is still increasing.
3 [C ] (technical) a death: hospital mortalities (= deaths in hospital)

I could very well be wrong though.
Thanks!
Yes, sorry Julie - I left "rate" out.
I really don't know how incidence and fatality appeared.I was wondering only about the meanings of mortality and morbidity because they seem rather the same.

Thanks
