If this is real -- does anyone know what substance they may be spraying and/or what the purpose is?

70% ethanol is effective on viruses with a lipid membrane (coronaviruses, influenza viruses, paramyxoviruses {measles, mumps, parainfluenza viruses, etc.}, & even Ebola viruses. When alcohol evaporates, it dehydrates the viral particles & destroys the viral membrane.

Replying to @VirusWhisperer @hbdchick and
That is completely incorrect. Evaporation has absolutely nothing to do with antimicrobial activity of alcohols. It's EXPOSURE of biological membranes and proteins to high concentration alcohols that destroys their structure. Oh, and membranes are NOT "dehydrated" by alcohols!

Replying to @dklndt @VirusWhisperer and
isn't a concentrated alcohol solution hygroscopic, in addition to alcohol being able to denature proteins, etc. ? should pull water away. agree that "evaporation" is not the precise mechanism, but if it pulls water out and the solution evaporates, that is dehydration. semantics.

ps: sorry about “semantics.” ran out of characters in tweet.
