A high incidence of a disease will result in a high prevalence, but it does not necessarily follow that high prevalence.1.Prevalence is a measure of the number of cases of a disease in a certain population for a specific period of time while incidence is a measure of the number of new cases of the disease.Please note: comment moderation is enabled and may delay your comment.

The first assumption we make is that the population is,If each of the assumptions are met, then we can derive the following relationship between prevalence.This states that the prevalence is approximately equal to the incidence multiplied by the average duration!It’s important for you to understand that this relationship is conceptual, not deterministic. /ExtGState << 10 0 obj endobj /LW 1 The Rothman and Greenland book is always a place to start.

They are used to determine the rate at which the disease is spreading and the number of people who are at risk.Both prevalence and incidence are measures of distribution of a disease in a population. <<

Incidence in epidemiology is a measure of the probability of occurrence of a given medical condition in a population within a specified period of time. 8 0 obj << %PDF-1.2 However, to say that the prevalence of pancreatic cancer, say, must be 2,204 cases in our population because the incidence in 4,408 cases per person-year and the average duration of pancreatic cancer is 0.5 years is wrong. << 2 0 obj /BM /Normal /ca 1 << /G12 9 0 R /Length 4601 /ProcSet [/PDF /Text /ImageB /ImageC /ImageI] /ColorSpace /DeviceRGB /BitsPerComponent 8
