Now a bit of my story as a "front line healthcare worker" (medical imaging in a busy hospital) in the USA:
I have performed computed tomography exams on numerous patients who have been confirmed with and/or are being tested for COVID.
Couple of examples of my typical work week:
Patient came into the ER last week c/o abdominal pain. I did a CT abdomen/pelvis on him wearing nothing more than my usual surgical mask & gloves. Same patient came back two days later c/o shortness of breath. COVID test ordered, and a CT Chest. I garbed up (N95 mask, plastic gown, face shield, gloves, etc.), did his scan, test results come back positive for COVID. So, I was exposed to COVID a few days earlier without wearing the full protective suit.
Monday of this week, a patient came into the ER c/o abdominal pain. I did a CT abdomen/pelvis on her wearing nothing more than my usual surgical mask & gloves. Noticed while I was doing the scan that she seemed confused. Couple hours later, the provider ordered a COVID test and a CT Head. I garb up in full protective gear, go get her again and scan her head. Didn't even bother to see if her COVID test came back positive or not.
I have been exposed so many times now that it no longer matters. I have never felt ill, or had any symptoms. Would like to have the test to see if I have the antibodies.
