- Your screening facility can process 1,000 people per week. Assume you are attempting the early detection of a disease with a prevalence of 2%, and your test has a sensitivity of 95% and a specificity of 90%. D- what is the positive predictive value of the screening test? E- what is the negative predictive value of the screening test? F- what would happen to the negative predictive value of the screening test if the prevalence was 5%?69. An epidemic curve is constructed mainly by:I. Plotting the time on the x axisII. Plotting the time on the y axisIII. Plotting the number of new cases on the x axisIV. Plotting the number of new cases on the y axis A. I AND IV B. I, AND III C. II AND III D. II AND IVB. One of the most memorable epidemiologic incidents in the Philippines was the sudden food poisoning of school children in Bohol which killed 15 children while 240 others being crippled. As an epidemiologist, you are tasked to go the place and conduct an independent epidemiologic analysis using retrospective cohort study design. Design a method following this design. Your method must answer the following specific questions: a. What will be your cohort groups? Define your cohorts. b. What questions/exposures will your survey instrument contain? c. How will you gather your data? d. How will you interpret your data? e. Provide a plausible causal narrative to your “theoretical data”
- 71. Which of the following pertains to a POINT SOURCE epidemic curve? I. Ongoing source of contaminationII. Relatively brief exposure periodIII. Same incubation periodIV. Infection spreads from person to person A. I, and II B. II and III C. II and IV D. III and IVGive several examples of disease keys, diagrams, and scales that are widely used for disease assessment. Are any of these methods for quantifying amount of disease superior to other methods? Explain your answer1. First, describe your chosen public health issues topic. a. Then, explain why you chose the topic. b. Finally, explain the topic’s relevance to public health. (We suggest citing reading and lecture material to demonstrate your understanding of public health.] [Minimum of 150 words] 2. Who is impacted by this issue, and why? a. Include epidemiological evidence, such as incidence or prevalence or population-based data, if it exists. b. Are certain populations more affected than others? c.Do health disparities exist? Explain. [Minimum of 150 words.] 3. How might different stakeholders (an individual or group with an invested interest in the topic ) understand the issue? [Minimum of 150 words.] a. Consider different parties like industry, government, healthcare, technology, various cultural groups, etc. You don’t have to describe each of these, but rather appreciate how any issue will include various perspectives. i.
