This is the key observation that somehow has not really made it outside of hospital circles. Still waiting for the first detailed report from a large health system of in-hospital transmissions in the universal masking era. Per hospital epis I’ve spoken with close to 0
This Lancet report gets highly referenced suggesting healthcare workers higher risk but 1) much of it pre-universal masking 2) don’t report whether community acquired (much of it is per other publications from healthcare) 3) no contact tracing

This paper of 226 patient contacts of healthcare workers w CoV2 (both pre and post universal masking) is probably the best 1 on the subject — they found one possible transmission, during a 30 minute encounter w both patient and healthcare worker unmasked

This paper is another important piece to this, but would still like to see how this change in high risk exposures translates to numbers of linked transmissions
And now: published yesterday in @JAMANetworkOpen, out of 9000+ patients admitted during Boston surge in universal masking era, TWO hospital acquired cases in patients, both w explanations

Obviously there are additional precautions for patients so some caveats to generalization — why I would like to see this amount of detail about healthcare worker infections
