multi-state outbreaks

Multi-state outbreaks occur when a contagious disease spreads across multiple states, often linked by common sources like contaminated food, water, or products. These outbreaks involve cases reported in different regions, highlighting how the disease can travel beyond local areas through travel, trade, or shared supplies. Detecting and investigating multi-state outbreaks help public health agencies identify sources, control the spread, and prevent further infections on a broader scale.
