When investigating an outbreak of a food-borne illness what demographics from the population being studied may be useful?
If you are conducting a survey, what questions should you ask the lab-confirmed cases?
Which biases may be introduced as a result of asking these questions, and how can their presence/effects be mitigated?1) Age, sex, etc.
2) Assuming a food-borne illness, where they ate, when symptoms started, what they recall eating, etc.
3) Response bias, interviewer bias, and recall bias may occur. Their presence may be mitigated by making sure all questions are partially worded and do not lead the participant.

Re: Disease Detectives B/C
What is the difference between an experimental and observational study? When might an epidemiologist use each type?

An experimental study involves an active attempt to change a disease determinant (as in exposure, or behavior). Meanwhile, an observational study is a study that allows nature (i.e. the DISEASE) to take its natural course while the epidemiologist only observes changes and characteristics and doesn't intervene. An epidemiologist may use an experimental study to determine plausible intervention/prevention methods for the disease. An epidemiologist may use an observational study to establish characteristics of the disease.

A hyperendemic disease is a disease that is constantly and consistently at a high prevalence rate within a population. Arthritis is a hyperendemic disease.
