Q: If you walk into a room where someone with #COVID has been previously, how long can infectious virus 
still be present?
A: Potentially, nearly 5 hours!
These researchers found that genetically identical #SarsCoV2 infected a patient who was admitted 4 hrs, 45 min post D/C of an asympto infected pt. Have to wonder if it’d be even longer if they’d been symptomatic…

Corsi-Rosenthal boxes (or far UV-C) lights would sure be useful in hospital settings - - and so many others!
@cbarbermd and people still solidly stare at me when I wear a mask indoors ffs
@cbarbermd There’s no reason any building, much less a hospital, should be allowed to operate with that bad of a ventilation system. It’s not just an infectious disease risk. What do you do with a building like that when there’s wildfire smoke in the area or some kind of toxic leak within the building? Unfortunately indoor air quality is virtually unregulated and any given building we enter could be exposing us to totally unnecessary risks.
@cbarbermd That is crazy. Unfortunately the article is paywalled. Just curious, how did they exclude that the virus was transmitted via smear infection? Did neither patient touch anything? (Not to imply they didn't do their due diligence, really just curious.)
