count cases in an outbreak, we like to put that tally to good use. We do this by creating an epidemic curve, or epi curve. While outbreak investigations can throw many unexpected curves, the epi curve is one that should be created in every potential outbreak situation. This issue of FOCUS explains how epi curves are used and describes meth-
Disease outbreak. In epidemiology, an outbreak is a sudden increase in occurrences of a disease when cases are in excess of normal expectancy for the location or season. It may affect a small and localized group or impact upon thousands of people across an entire continent. The number of cases varies according to the disease-causing agent, and ...
This Quick Learn lesson will take approximately 10 minutes to complete. When you are finished, you will be able to create an epidemic curve, or “epi curve.”. You can move through this lesson by using the NEXT and BACK icons below. An is a visual display of the onset of illness among cases associated with an outbreak.
Epidemiological curves or “epi curves” can shed light on whether. An outbreak is most likely due to a point source or person-to-person transmission; An outbreak is increasing or waning; The pathogen has a long or short incubation period; Create an epi curve. Create an epi curve using the Generate an Epi Curve [2 sheets] template.
In some common-source outbreaks, case-patients may have been exposed over a period of days, weeks, or longer. In a continuous common-source outbreak, the range of exposures and range of incubation periods tend to flatten and widen the peaks of the epidemic curve (Figure 1.22).The epidemic curve of an intermittent common-source outbreak often has a pattern reflecting the intermittent nature of ...

The data on the coronavirus pandemic is updated daily.
This exercise uses an outbreak line list to create PivotTables in Microsoft Excel and use them to extract information for descriptive epidemiological summaries and create epidemic curves. Toolkit epidemiological summary template. This Microsoft Word document provides a suggested template for the content and layout of an epidemiological summary.
