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

The potential role of aerosol transmission for seasonal respiratory viruses has been dramatically highlighted during the ongoing COVID-19 pandemic.

This article highlights and discusses various studies that form the basis for this hypothesis.
