Correct answer: E — Create a line list with key variables

Create a line list with key variables is the single best answer because a line list organises cases by demographics, onset date, location, exposure and outcome. Publish anecdotal reports is plausible in a related presentation, but it is less appropriate because it does not fit the key discriminator in this vignette. The teaching point is that it is central to epidemic curves, mapping and response prioritisation.
