Visual Timeline of Events
USER GUIDE & TEMPLATE
A Visual Chronology illustrates high-level activities that occurred during an investigation using an epidemic curve.
WHAT YOU WILL NEED
1.Chronology of Events
- Although events to be included in the timeline are specific to each investigation, consider including:
- Date when an event is first identified or when the lead agency is notified
- Date the outbreak is declared (start date) and date when it is declared over (end date)
- Dates of OICC activation and deactivation
- Date the investigation is expanded (e.g. a new province is added)
- Date that an epidemiological assessment is prepared for a health risk assessment
- Dates of important findings (e.g. traceback findings, laboratory positive food sample, epidemiologic study)
- Dates of public health action: communications: to public health professionals (e.g. public health alert) or the public (e.g. public health notice); recall of products.
2.Two Epidemic Curves
- Using the line list for the investigation, create two epidemic curves in Excel with identical axes.
- Number of Confirmed Cases by Date of Onset
- Number of Confirmed Cases by Date Reported to Public Health
- The event details should be condensed and written in present tense.
- The events need to be categorized into one of the following categories:
- Outbreak Identification & Source Implication
- Traceback and Regulatory Activities, and Results of Product Testing
PUTTING IT ALL TOGETHER
Using the template in this guide (Page 2), you can create a visual “Timeline of Events”.
1.In the “Design” menu, choose the orientation of the timeline (i.e. portrait or landscape) .
2.Copy over two epidemic curves (paste as “Picture format”) into the template – keep them the same size.
3.Using the box & lines provided in the template; create as many copies as needed.
4.Place the chronology content in the appropriate event box :
- In the Blue boxes, place the Outbreak Identification & Source Implication content
- In the Green Boxes, place the Traceback and Regulatory Activities (and results of product testing)
5.Using the connectors/lines, match the date in the event box to the date on the epidemic curves
6.Format/move/add/delete event boxes and lines as needed
- Ensure all Fonts are the same and arrange/format the visual timeline to your preference
- Tip: When the connector/line is selected, a yellow icon appears that can be used to readjust the orientation
- Tip: Group and ungroup the line and box objects as needed (right-click the objects >> select “group”)
