the striking of a light beam on a surface; "he measured the angle of incidence of the reflected light" the relative frequency of occurrence of something
probability that healthy hosts will develop a disease during a specified period of time; ie the number of new cases of a disease in a population over a period of time
The number of new cases of a disease or occurrences of an event in a particular time period, usually expressed as a rate, with the number of cases as the numerator and the population at risk as the denominator Incidence rates are often presented in standard terms, such as the number of new cases per 100,000 population
{i} frequency, rate of occurrence; occurrence, instance; falling of a ray of light (or anything else which moves in a straight line) on a surface (Optics, Physics)
the number of new cases of a diseases or condition in a specific population over a given period of time The incidence rate is determined by dividing the number of new cases by the total population
The incidence of something bad, such as a disease, is the frequency with which it occurs, or the occasions when it occurs. The incidence of breast cancer increases with age. the number of times something happens, especially crime, disease etc rate incidence of
the number of cases of a disease, abnormality, accident, etc , arising in a defined population during a stated period, expressed as a proportion, such as x cases per 1000 persons per year 1
The frequency of new occurrences of a condition within a defined time interval The incidence rate is the number of new cases of specific disease divided by the number of people in a population over a specified period of time, usually one year
