You are an epidemiologist interested in food poisoning caused by salmonella.
Using the South University Online Library or the Internet, conduct a research to gain additional insight into the causes of food poisoning.
Based on your research, answer the following questions:
- What are the different types of screening or diagnostic tests available to study salmonella? What the advantages and drawbacks of each of the tests?
- If you were asked to employ the use of screening or diagnostic tests to study the transmission of salmonella, which screening or diagnostic tests would you recommend? Why?
- For each test, which of the following principles would influence the study outcome and results:
- Bias
- Confounding
- Values of sensitivity on epidemiological study validity
- Values of specificity on epidemiological study validity
- How will each principle influence the results of your epidemiological study based upon the type of screening or diagnostic tool?
- Which screening or diagnostic tool would you recommend as the most effective in the epidemiological study of salmonella transmission? Why?
