ABSTRACT
As SARS-CoV-2 has swept the planet, intermittent lockdowns have become a regular feature to control transmission. References to so-called recurring waves of infections remain pervasive among news headlines, political messaging, and public health sources. We explore the power of analogies to facilitate understanding of biological models and processes by reviewing strengths and limitations of analogies used throughout the COVID-19 pandemic. We consider how, when analogies fall short, their ability to persuade can mislead public perception, even if unintentionally. Although waves can convey patterns of disease outbreak, we suggest process-based analogies might be more effective communication tools, given that they can be easily mapped to underlying epidemiological concepts and extended to include complex dynamics. Although no single analogy perfectly captures disease dynamics, fire is particularly suitable for visualizing epidemiological models, underscoring the importance and reasoning behind control strategies and potentially conveying a sense of urgency that can galvanize individual and collective action.
