Let's start with the citation you provided. It is an AI summary of a single case study not yet published. That is hardly a basis for saying the doctors "should have known" about the issue.

Did you know that in many practices, docs and their staffs often use flow charts or questionnaires to narrow down diagnoses and figure out how to proceed? These take time to update after new information comes out, gets vetted for accuracy and become establishesd protocol. Not everyone doc can read every bit of information that comes out in addition to seeing patients, managing the documentation and dealing with insurance companies.

I would say the message here is "stay tuned for further developments"
