Abstract		Frequency measures are quantities that express frequency of health phenomena. Prevalence and incidence are two main groups of frequency measures. The most distinctive difference between these two groups is that by prevalence measures we are observing the transversal section through the situation of phenomenon under observation at designated time (e.g. in a point of time) while by incidence measures we are observing its dynamics (by performing regular observation of breaking out of new cases of phenomenon under observation during every of specified equal time periods) in a specified population.
