The rate at which new cases of disease occur in a population. The numerator is the number of new cases of disease occurring in a given period; the denominator is the population at risk of acquiring the disease.
The number of cases of a specific illness diagnosed or reported during a stated period of time, divided by the number of people at risk for the disease. Example: Five children develop measles in a community of 5,000 people during one year: The incidence rate of measles in that community is 5/5000 or 1 per 1,000 people per year.
The number of new cases of an illness occurring in a population over a period of time. The numerator is the number of new cases occurring in a given time period and the denominator is the population at risk during the same time period.
Rate of job-related injuries and illnesses.
Indicates the number of workplace injuries/illnesses and the number of lost work days per 100 employees.
The number of persons becoming ill in a defined population within a period of time.
The number of new cases of a given type of cancer per person in the general population(usually expressed as a rate per 100,000).
The number of new WMD occurring during a year per 100 full-time equivalent workers. Incidence rates are calculated as follows: (Number of new WMD in problem jobs) X (200,000 hours or 100 full-time equivalent workers) / (Work hours per year or number of full-time equivalent workers in problem jobs).
Number of new events in a given population during a given time frame in a given geographic area per 100,000 people.
the rate at which people without a health problem develop the problem during a specific time, (i.e., the number of new cases developing in a population over a period of time).
The occurrence of new cases of a disease or condition within a specified time frame.
The incidence rate is the number of lost time injuries and diseases for each one hundred workers employed. The formula used is: number of LTI/Ds x 100 number of workers The number of workers is defined as the average number of workers covered by the compensation system who worked during the relevant period. As a result of treating casual, seasonal and part and full-time workers equally, incidence rates can give misleading indications of relative risk. This is relevant to industries with high levels of part-time employment where the number of workers employed may be comparatively high but the actual exposure to hazards (reflected in actual hours worked) may be less.
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 new cases occurring during a given time period.
The number of new cases of a disease occurring in a period of time divided by the size of the population at risk of becoming a case during that period of time. The result is often multiplied by a base number, such as 1,000 or 100,000.
is the number of new cases during a specific time period/size of the population at risk. In terms of incidence rate, "crude" is the total members at or during a given time; "specific" is the incidence rate divided by categories (age-specific, disease-specific, mortality); "adjusted rate" is the rate adjusted to a standard population based on characteristics which may influence the outcome, e.g. age-adjusted mortality.
The number of new cases of a disease (or injury or other health-related condition) over a given period in a defined population, divided by the population at risk of contracting the disease. The population at risk is usually taken as the mid-period population. Theoretically, persons who have already got the disease should be excluded from the at risk population, but that is often not possible. Incidence data are valuable in investigations of disease aetiology (causes).
The number of new cancer cases per 100,000 people, per year.
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.
The number of new cases in the population during a specified period of time.
the number of newly diagnosed cases of disease in a specific population during a specific time period per "x" number of people; usually the time period is one year and "x" number of people is 100,000.
as defined by OSHA, is the number of occupational injuries and/or illnesses or lost workdays per 100 full-time employees.
The rate at which new injuries and illnesses occur for a given job, production line, work area, department or the company.
Occurrence of a disease per 1,000 people as used in statistics.
the number of new cases of a disease in a defined population over a specified period of time.
The ratio of new cases within a population to the total population at risk given a specified period of time.
the number of new cases of a certain disease appearing during a certain period of time expressed relative to the size of the population, e.g., 60 new cases of breast cancer per 100,000 women per year.
The number of persons contracting a disease per 1,000 population at risk, for a given period of time. Source: PRB
the number of new events occurring in a given time period in a population.
