OUTBREAK INVESTIGATION REPORT WRITING GUIDELINE

A.           Introduction

[A brief summary of the outbreak/setting the scene for the reader. In this section preferably signpost the reader so they are clear about what to expect from the report that they are about to read]

B.           Background

[Briefly describe- when the outbreak occurred; how the outbreak was discovered; where or what sources (e.g. foods) were implicated.]

C.           Investigation of the outbreak (this is the section where critical appraisal will be assessed) [Highlight some epidemiological, environmental and microbiological aspects]

1.    Confirm that this is really an outbreak

·         First critically discuss the definition of outbreak using different sources of literature.

·         Critically discuss whether the case discussed in the report was an outbreak or not.

·         How was the outbreak discovered, and when?

·         Was there a surveillance system in place in the setting where the outbreak was discovered?

2.    Critically discuss what a case definition is and put together a case definition that may include the person, place, and time and also the symptoms. Discuss if this is the definitive case definition or not.

3.    Critically describe cases; what sort of outbreak is this? Write about any informationabout the incubation period, age and gender of cases?

5.    Test hypothesis usually case/control study including Odds ratio. How the controls are were recruited? (If needed or given)

6.    What other information might be used to confirm the hypothesis? E.g. sampling of environment and/or food.
