Ugh Norovirus. I work in a daycare, one day during nap (and after lunch) one of my students woke up and started vomiting everywhere, so I took her to the bathroom to clean her up and while I was gone ANOTHER child vomited, so they brought that child to the bathroom for me to clean. Eventually 10 of my students ended up vomiting all at the same time, it was a nightmare. We had to pull teachers from other classrooms to come help in my classroom because all of the teachers from my classroom were busy cleaning children who had been sick. The next day I had it, and only two of my students showed up on a classroom of 15. Worst day of my professional life so far.
