Infection rate
Infection Rate
Infection rate (pronunciation: /ɪnˈfɛkʃən reɪt/) is a term used in epidemiology to describe the frequency of new instances of infection within a population during a specific time period.
Etymology
The term "infection rate" is derived from the Latin word 'infectio', meaning 'to taint or corrupt', and the Old French 'rate', which means 'ratio or proportion'.
Definition
Infection rate is a key measure in public health and epidemiology. It is calculated by dividing the number of new infections during a time period by the size of the population initially at risk.
