      Reupping. Yes, we knew about asymptomatic and presymptomatic infectivity with a high degree of certainty from the diamond princess cruise ship. That outbreak began February 3, 2020.https://twitter.com/DFisman/status/1286004357239123970 …

      It’s easy to forget how much pushback there was on testing widely, how much resistance there was to the idea that asymptomatic workers could be infecting residents, and how slow Ontario officials were to “uncouple” facilities by restricting movement of staff.

      The identification of asymptomatic infection was so striking and important that Hiroshi Nishiura used it as a basis to estimate fraction of infections that are truly asymptomatic (around 1/5), validated by subsequent meta analyseshttps://pubmed.ncbi.nlm.nih.gov/32179137/

      Gabriel Leung and others had sounded the alarm on the importance of presymptomatic infection and it’s contribution to many (50% or so) transmissions. This data was *published* in by mid-April 2020.https://www.nature.com/articles/s41591-020-0869-5 …

      In Nature. Nature. Not a preprint. Peer reviewed and published in Nature.

      Gabriel’s observations formed the basis for his strong recommendation on masking for source control, which was amplified against tremendous resistance in Ontario by @jkwan_md

      Replying to @DFisman @jkwan_md

      Chinese scientists were telling us this at end of January, and yeah, Diamond Princess data sealed it. I had no problem ~"getting transmission without symptoms is happening" (hence need universal source-control) past fact-checkers by March because there were *so many* sources...
