Understanding Aerosol-Mediated Disease Transmission

This Outlook aims to update the longstanding treatment of airborne disease transmission through an interdisciplinary lens combining biology, surface chemistry, and aerosol physics, drawing parallels between environmental and human-generated infectious aerosols and examining their effects on human and ecosystem health. By recasting the lung surface as a dynamic interface akin to the ocean surface, this Outlook illustrates the importance of a multidisciplinary approach to elucidate the mechanisms of disease transmission at a depth that enables practical mitigation strategies. The urgency of this analysis is motivated by the evolving nature of airborne pathogens of concern, such as SARS-CoV-2 and influenza, and the global impact of dynamic environments on the poorly understood airborne microbiome.
