Step 6: Develop Hypotheses
•Consider what is known about the disease:
•
–What is the agent’s usual reservoir?
–
–How is it usually transmitted?
–
–What are the known risk factors?
–
–“Round up the usual suspects”
Speaking Points

Prior to developing hypotheses, consider what is known about the disease:

•What is the agent’s usual reservoir?

•How is it usually transmitted?

•What are the known risk factors?

•Based on what you know you can “Round up the usual suspects” – for example, if the agent is typically transmitted via an oral-fecal route, you may suspect an infected food handler at a  particular restaurant may be the source
