What Methods are Used to Investigate Disease Clusters?

The investigation of disease clusters often follows a structured approach:
1. Preliminary Assessment: Gathering initial data and determining if a potential cluster exists.
2. Descriptive Epidemiology: Characterizing the cluster by time, place, and person.
3. Analytical Studies: Conducting case-control or cohort studies to identify potential risk factors.
4. Exposure Assessment: Evaluating potential sources of exposure (e.g., environmental contaminants).
5. Risk Communication: Communicating findings to the public and stakeholders effectively.
