New research estimates that Sars-CoV-2 droplets encased in mucus can remain moist for up to 30 minutes and travel up to about 200 feet.
“Here we show that mucus shells increase the drying time by orders of magnitude so that enveloped virions may remain well hydrated and, thus, fully infective at substantial distances. This provides a mechanism by which infective enveloped virus particles can transmit as aerosols within buildings and between buildings over extended distances.”
