Innsláttartíðni

Innsláttartíðni is an Icelandic term that translates to "insertion frequency" or "incidence rate" in English. It refers to the rate at which new cases of a particular disease or condition occur within a defined population over a specific period of time. This metric is crucial in epidemiology for understanding the spread and burden of diseases.

Calculating innsláttartíðni involves identifying the number of new cases diagnosed during a given period and dividing it by the total population at risk during that same period. The result is typically expressed as a rate per a standard population size, such as per 1,000 or 100,000 people. For instance, if a country records 50 new cases of a certain illness in a year among a population of 1 million, the innsláttartíðni for that year would be 50 per 100,000.

This measure helps public health officials track disease trends, allocate resources, and evaluate the effectiveness of prevention and intervention strategies. A rising innsláttartíðni might indicate an outbreak or a growing problem, while a declining rate could suggest successful control measures. It is distinct from prevalence, which measures the total number of existing cases (both new and old) at a given point in time. Innsláttartíðni focuses specifically on the emergence of new instances.
