(epidemiology) Measure of the frequency at which new events occur in a population. Note: This is the value obtained by dividing the number of new events that occur in a defined period by the populatio [..]

The number of persons contracting a disease per 1,000 population at risk, for a given period of time.

Indicates the number of workplace injuries/illnesses and the number of lost work days per 100 employees.

Represents the number of injuries and/or illnesses per 100 full-time workers, calculated as follows: (N/EH) X 200,000, where: N = number of injuries and/or illnesses, EH = total hours worked by all em [..]

The ratio of the number of new cancers of a specific site/type occurring in a specified population during a year to the number of individuals who were at risk for the given cancer, generally expressed [..]

In epidemiology, an incidence rate is the number of new cases in a defined population in a given time period. The incidence rate should not be confused with the prevalence rate, which is a measure of the total number of cases (for example, of problem gambling) in a given population at a designated time and includes new and existing cases.

Frequency of occurrence per unit of potential occurrence

(DOL) - The number of occupational injuries and/or illnesses, or lost workdays, experienced by 100 full-time workers during a given year. This may be expressed as: Incidence Rate=(N x 200,000)/EH, whe [..]

The rate at which new events occur in a population. The numerator is the number of new events that occur in a defined period; the denominator is the population at risk of experiencing the event during [..]

The proportion of a population that has a particular condition that began during a given time period. An incidence rate is measured in one of three ways: attack rate, incidence density rate, or cumulative incidence risk.

A measure of the frequency with which an event, such as a new case of illness, occurs in a population over a period of time. The denominator is the population at risk; the numerator is the number of n [..]

is the number of new cases (i.e. people newly acquiring a disease or an attribute) developing during a specific period of time divided by the total disease free person-time of observation seen in the population at risk.

the total number of new cases of a disease (or condition) divided by person-time at risk.                                                                                                                                                                                             [..]

  the number of instances of illness commencing, or of persons falling ill, during a given period in a specified population divided by the population at risk

1) The number of new cases (that is, incidences) of a disease that develop in a defined population over a period of time. The numerator is the number of new cases of a given disease occurring during t [..]
