Exercise 14

What is the primary distinction between a cluster and a sentinel health-related state or event?

Step 1 of 3

A disease cluster is the unusual aggregation (which can be either real or perceived), of health issues that are grouped altogether in space and time and is reported to a health institution. It occurs when a physical stress, psychosocial condition or a biological/chemical agent is suddenly introduced into the human environment.
