- Calculating Incidence versus Prevalence The picture represents 10 new cases of illness over about 15 months in a population of 20 persons. Each horizontal line represents one person. The down arrow indicates the date of onset of illness. The solid line represents the duration of illness. The up arrow and the cross represent the date of recovery and date of death, respectively. The picture New: Cases of Illness from October 1, 2004–September 30, 2005 Question: Calculate the period prevalence from October 1, 2004, to September 30, 2005. The numerator of period prevalence includes anyone who was ill any time during the period. In Figure 3.1, the first 10 persons were all ill at some time during the period.Calculating Incidence versus Prevalence The picture represents 10 new cases of illness over about 15 months in a population of 20 persons.

- Rates of disease and death are elevated for historically marginalized racial groups, blacks (or African Americans), Native Americans (or American Indians and Alaska Natives), and Native Hawaiians and Other Pacific Islanders, who tend to have an earlier onset of illness, more aggressive progression of disease, and poorer survival. True OR False34) During a cohort study of 5000 children, the occurrence of Disease X is measured over a 5-year period. On average 20 children have signs and symptoms of Disease X each day. Over the 5-year period, the diagnosis of Disease X is rendered 30,000 times. Which of the following relationships of incidence and prevalence best describes the characteristics of Disease X? a. High incidence and high prevalence, indicative of a short-duration curable disease b. High incidence but low prevalence, indicative of a chronic incurable disease c. High incidence but low prevalence, indicative of a short-duration curable disease d. Low incidence and low prevalence, not predictive of specific disease behavior e. Low incidence but high prevalence, indicative of a chronic incurable diseaseVisit the website of the National Center for Health Statistics.
