So I went to the clinic today to get checked out. Saw a PA as no MDs were available. Was swabbed for influenza... negative. The PA said it could still be flu; apparently the sensitivity of the test is somewhat less than 100%.
But I'm spending the day at home, and tomorrow is my non-teaching day, so I'll probably stay home tomorrow too. Colleagues are taking my classes (how I hate asking them!) The PA said I should stay home until 48 hours without fever. Hmmm... students are told to wait 24 hours. I wonder why the difference?
