Hypothesis: All respiratory viruses (including SARS-CoV-2) are aerosol-transmitted

Abstract

The potential role of aerosol transmission for seasonal respiratory viruses has been dramatically highlighted during the ongoing COVID-19 pandemic. It is now evident that short-range (conversational) and long-range aerosol transmission plays at least some part in how all these respiratory viruses are transmitted between people. This article highlights and discusses various studies that form the basis for this hypothesis.
