Two values often used by infectious disease epidemiologists to gauge the infectiousness of a disease are R-nought, and the level of herd immunity needed to stop a disease from spreading. In this interactable application, you will explore what these numbers mean, how they are used and what they can tell us about the size and timing of a disease outbreak.
