5/ Why? Because we have a universal masking policy for surgical masks + eye protection. And we only wear N95 masks if the patient is on enhanced respiratory precautions. The index case, after two neg tests, despite ongoing symptoms, was removed from these precautions.

6/ We have had subsequent outbreaks even after this, albeit smaller; it was one of the main reasons why I chose to wear N95s in almost all patient rooms for a time- and had the rest of our medicine team also do that back in December. It’s easy to do- low hanging fruit here.

8/ So here we now have a case of
#covid19 transmission between patient & staff despite both wearing surgical masks; and the staff also wearing eye protection. And as the authors point out, it is exceedingly difficult to isolate this bc usually have many confounding contactspic.twitter.com/kjhXmrfmkH

Replying to @AbraarKaran @RanuDhillon and
Isn't that the cluster with nebulizer use by the index case, though? Let me check.

Yes there was nebulizer use at points during the admission, but the transmission described in the tweet I tagged you in is not during nebulizer use- it’s during a CT scan.
