Which of the following scenarios is the least likely to result in a decrease in disease prevalence in a specific population? (assume that there is no migration into or from the population)   a. Emergence of a new curative treatment, while incidence remains the same as before   b. A more relaxed case definition for the disease, while survival and cure rates remain the same as before   c. A worsening of disease reporting standards leading to underreporting of cases, while survival and cure rates remains the same as before   d. Higher mortality from the disease, while incidence remains the same as before

What is a notifiable disease? Group of answer choices A disease that is highly contagious. A disease that must be reported to the CDC. A disease that has a high mortality rate A disease that is suspected to be caused by terrorists.

There are multiple epidemiologic study designs.  Study designs can be categorized as an experimental or observational design.  What is the primary difference between the two? (Choose the one best answer)      1. In an experimental design, the outcome/disease is assigned 2. In an observational design, the outcome/disease is assigned 3. In an experimental design, the exposure/treatment is assigned 4. In an observational design, the exposure/treatment is assigned 5. They are both epidemiologic study designs without a distinct difference

For each of the studies below, put an “A” if it is an example of analytic epidemiology or a “B” if is an example of descriptive epidemiology. __________ Analysis of US mortality data to determine the rates of colorectal cancer deaths for white (non-Hispanic), black (non-Hispanic) and Hispanics in 2012. __________ Analysis of survey and laboratory data to determine if individuals with a high salt diet have higher systolic and diastolic blood pressure. ______ Case-control study to determine if patients with a current diagnosis of breast cancer had ever received hormone replacement therapy. ______ Analysis of medical records to determine if diagnosis of hypertension is more or less common among adults age 65 or older compared to those younger than age 65.
