I'm sure your students aren't at all upset that you haven't graded thier labs yet! I know what you mean about the beasties, but I've learned the hard way that those are better than the infection. There's always that pill you take once...can't remember the name of it, but it's good stuff. I had face surgery last spring and had to have major antibiotic therapy. That antifungal pill was amazing.
Hope you're on the mend soon, Caryl! xoxo
