I work with a guy who is in remission from Mantle Cell Lymphoma he takes immunosuppressants slept in the same bed as his wife who had the ronna he didn’t get it for nearly a year.   It’s very odd who gets it and who doesn’t.  I was around someone who had a bad case of it I never caught it until 2 years later and we have no clue where we got it. When I tested positive I tossed the test in the trash and went out and bought my Freightliner.
