I'm doing an LTS job at a school that apparently had a lice outbreak a few months before I got there. I'm not sure what constitutes "outbreak," but I have an aide who thinks every time a kid scratches his/her head it's lice. She was even convinced she had it but it turned out to be nothing. Since I've been there, they found one bug in one kid's hair, which led to having to check all of them. Several weeks later a parent claimed to have found it in another kid's hair, but the nurse said it was just dead nits. The parent's claim, however, led to another check of my whole class. This check led to one more child found with nits. The parent said it was just dry skin and that the nurse was wrong. So...I'm wondering...is this panic overblown? Is it possible there really is no problem at all? Could the nurse be wrong? Has anyone else gone through this whole yes, it's lice/no, it isn't lice? How hard is it to really tell?
