    If this isn't a smoking gun, then I don't know what is. Successful isolation (cytopathic effect) of SARS-CoV-2 in aerosols collected 2-5 m from patients, genome identical to NP swab, TCID50:genome copies close to 1:1! /1https://twitter.com/Lucas_Bolivian/status/1291428908735188992 …

        Good negative controls. Kudos to CY Wu's group and collaborators for developing the condensation collection technique, which gently collects virus from air to preserve infectivity. /2

        Viable SARS-COV-2 virus was collected from the air 6 to 15 feet from the infected. This is AMAZING news! Because now the @WHO and @CDCDirector will have to acknowledge aerosols formally. Which changes guidance for every single medical organization out there. For you?

        so this means 6 ft + ordinary masks + filtration ≠ safety, in an indoor context?

        Linsey could you simplify what this means for the average person?

        When I read this it’s like when I watch formula 1 engineers build a car. I’m totally interested. Like super interested. I’ll nod and stuff like I know what’s going on, but really, I’m a dog watching people on a trampoline.
