In a population of 5,000 people, 100 ate spinach contaminated with E. coli (O157:H7) and became ill. Of the ill, 15 died. What was the case fatality rate? (A) 20 per 1,000 (B) 3 per 1,000 (C) 150 per 1,000 (D) 15 deaths

In a population of 5,000 people, 100 ate spinach contaminated with E. coli (O157:H7) and became ill. Of the ill, 15 died. What was the case fatality rate? (C) 150 per 1,000 The numerator for case fatality is “number of individuals dying during a specified period of time from the disease of interest” and the denominator is “number of persons with the disease of interest.” In this question, the numerator is 15 and the denominator is 100. 15/100 = 0.15 X 1000 = 150/1000 persons.

Q: Case Fatality Rate (CFR)

A mathematical quantity that describes the severity of a disease; usually applied to acute diseases. It is the proportion of persons diagnosed with a disease who actually die from the disease during the period of observation. More test answers on https://studyhippo.com/hosa-epidemiology/

What is Case Fatality Rate?

Case Fatality Rate (CFR) is a measure of the severity of a disease that is used to assess how deadly it is. It is calculated by dividing the number of deaths caused by a particular disease or condition over a period of time, by the total number of cases reported during that same period. The result is expressed as a percentage.The Case Fatality Rate can be used to compare different diseases and conditions, and aid in decision-making regarding public health interventions. For example, if two diseases have similar incidence rates but one has a much higher CFR than the other, then it would make more sense to prioritize resources toward that disease in order to reduce mortality rates. Similarly, if two diseases have similar CFRs but one has a much higher incidence rate than the other, then it would indicate that more interventions are needed for prevention or control of this particular disease in order to reduce its burden on society.In addition to comparing different diseases and conditions, Case Fatality Rates can also provide insight into trends over time within an individual population or region. For example, if two years have nearly identical CFRs but one year saw an increase in reported cases while the other saw fewer cases reported, this could be taken as an indication that morbidity associated with this particular condition had decreased over time in that region suggesting successful public health interventions. Overall, Case Fatality Rates are important because they provide valuable insights into both specific diseases and populations which can help inform decisions regarding public health interventions and resource allocation.
