demographics, lab data, and risk factors or relevant exposures
should be included, but NOT open ended questions - ANSWER-
False - include open ended questions

simultaneously or be repeated as new information is received -
ANSWER-True
What are the first four steps of an outbreak investigation? -
ANSWER-1. Verify the diagnosis/confirm the outbreak

epidemiology
4. Develop a hypothesis

The ability to find true positives based on a single biologic sample
take at a point in time is defined as the ? - ANSWER-Sensitivity
The ability to find true negatives based on a single biologic
sample taken at a point in time is defined as the ? - ANSWER-
Specificity
What is the mathematical formula for sensitivity? - ANSWER-
(True positives) / (True Positives + False Negatives)

What is the mathematical formula for specificity? - ANSWER-
(True Negatives) / (True Negatives + False Positives)
Standard 2x2 table = D/(B+D)
