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 disease
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%?

Zika virus is chiefly spread using an insect vector, more specifically, mosquitoes. Given this, which of the following helps account for why all blood donations in J.S. are screened for Zika? O a. Zika can be easily transmitted from person to person even through incidental contact O b. Zika infections are now common and regularly reported in every U.S. State (except Alaska) O c. Screening of blood donations is the main way in which Zika infections are diagnosed in the U.S. O d. Climate change extends the habitat of mosquitoes that can carry the virus Next page
The City Department of Health has found out that a very infectious strain of influenza (transmission probability 0.3) is likely to hit soon for which the current vaccine is not effective. So far the DOH think about 100 people in the city have been infected. We know that influenza illness usually lasts for an average of 5 days and for every 1000 people who get influenza 1 person requires intensive care for 2 days. The population in the city is 80,000. The R0 (the basic reproductive rate) for this strain of influenza has initially been estimated to be 4. What is the likely contact rate for this epidemic of influenza?
An enzyme immunoassay for the detection of chlamydia trachomatis in cervical specimens has a sensitivity of 75% and a specificity of 98% when compared with culture. This test will be used by an HMO to screen women of reproductive age who are receiving their annual examination. A previous study, which used culture to screen 1000 women, determined that the prevalence of infection was 2%. In this population, which of the following is the predictive value of a positive screening test?

What do you think about the longitudinal NIH-funded Bogalusa Heart Study, created by cardiologist Gerald Bevenson in 1972? This study is following 16,000 who started in childhood and are now adults (40 years thus far). Researchers have looked at several things, on those living, as well as performing autopsies on 560 of these individuals who died since then (of accidental death or otherwise). 20% of autopsied children had plaques (fat deposits) in their coronary arteries, making this the first study of its kind to establish heart disease can exist in children, and those who were obese as children were likely to remain so in adulthood, as opposed to only 7% becoming obese who were not so in childhood.
In December 2020, a survey of 12,000 residents in Assisted Living Facilities (ALF) between 60 and 90 years old in Kentucky revealed that there were 600 cases of Covid-19 including 325 hospitalizations. Among those hospitalized were 200 women. The total population of Kentucky is 5,000,000. What is the prevalence of Covid-19 in ALF per 1,000 residents?
