I help organize a contra dance that requires N95s at half of our dances. Are there ways we could have a hall as safe as this but without the ways N95s make it harder to dance? I'm excited about supplementing ventilation and surgical masks with glycol vapor and 222-nm UVC: https://www.jefftk.com/p/alternatives-to-masks-for-infectious-aerosols

@jefftk nose spray containing iota-carrageenan is likely protective against Covid and other respiratory viruses. https://pubmed.ncbi.nlm.nih.gov/34629893/ and a survey for common cold https://pmc.ncbi.nlm.nih.gov/articles/PMC7880062/

However, unlikely you'll be sharing nose-spray among all the participants.

@dr2chase I do think some kind of nasal spray can make sense for respiratory protection, though I haven't looked into specifics. In this case, though, I'm looking at what are things organizers of events can do on top of whatever individuals are doing for their own protection.

(So this includes the source control benefits of masks, but not their respiratory protection benefits)
