- 34) 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 diseaseCalculating 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.

- 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 incidence rate from October 1, 2004, to September 30, 2005, using the midpoint population (population alive on April 1, 2005) as the denominator. Express the rate per 100 population.Note there are no cells on this panel that have a double dose (homozygous) of the K antigen. Which of the following statements is true regarding the K+k- phenotype? Question 6 options: A) The phenotype is rare due to the high prevalence of the k antigen in the population. B) The phenotype is uncommon but does occur in about 10% of the population. C) The phenotype occurs in about 50% of the population. D) Although the phenotype is not represented on this antibody panel, it is fairly common in the population.The frequency of a rare disorder expressed as an autosomalrecessive trait is 0.0064. Using the Hardy-Weinberg equation,determine the frequency of carriers for the disease in thispopulation.
