What is the first step in outbreak investigation?
Define the outbreak clearly. Identify the disease, affected population, and potential sources.
Why is establishing a case definition important?
It helps to confirm cases consistently and ensures accurate data collection.
True or False: Initial data collection happens after defining the outbreak.

Fill in the blank: The __________ step involves identifying the population at risk.
epidemiological assessment.
Cause → Effect: Identify a cause of outbreaks.
Contamination of food can lead to foodborne illness outbreaks.
What role does hypothesis generation play?
It guides further investigation and helps focus on potential sources.
How do you confirm a hypothesis in outbreak investigation?
Conduct additional studies, such as case-control studies, to examine associations.
