Understanding the distinction is critical for tracking outbreaks and guiding public health action. R0 (Basic Reproduction Number): The Potential R0 is the average number of secondary infections one infected person would cause in a fully susceptible population, with no immunity and no interventions in place. It's a theoretical baseline — a measure of a pathogen's inherent transmissibility under ideal conditions for spread.
