Morbidity rate
Morbidity Rate
Morbidity rate (pronunciation: /mɔːˈbɪdɪti reɪt/) is a term used in epidemiology to denote the frequency or proportion of individuals in a population who become ill or are affected by a particular disease during a specific time period.
Etymology
The term 'morbidity' is derived from the Latin word 'morbidus', meaning 'diseased' or 'unhealthy'. The suffix '-ity' is used to denote a state or condition, while 'rate' comes from the Latin 'rata', meaning 'fixed, settled'.
Definition
Morbidity rate is a measure of the incidence of disease in a population over a specific period, typically expressed per 1,000 or 100,000 individuals. It is a key indicator of population health and is used in public health research and planning.
Calculation
The morbidity rate is calculated by dividing the number of new cases of a disease during a specified time period by the total population at risk during the same time period, and then multiplying the result by a standard number (usually 1,000 or 100,000).
