===================================Which of the following sentences is not true:
a.Incidence rates describe the occurrence of new cases of a disease or condition in a community over a period of time relative to the size of the population at risk at the same time period.
b.Mortality rates, or rates of illness, in public health are incidence and prevalence rates.
c.A prevalence rate is the number of all cases of a specific disease or condition in a population at a given point in time relative to the population at the same point in time.
