What an Epi Curve Can Tell You
An epi curve is a visual display of the onset of illness among cases associated with an outbreak.
You can learn a lot about an outbreak from an epi curve, such as
- Time trend of the outbreak, that is, the distribution of cases over time
- “Outliers,” or cases that stand apart from the overall pattern
- General sense of the outbreak's magnitude
- Inferences about the outbreak's pattern of spread
- Most likely time of exposure
