The following situations have happened to me over the years (I work in a high school):
I have had student A (along with friends student B, C and D) come in to my office and tell me they are positive student E has lice.
I have had student L's parent call me telling me that student L saw lice on student M and they just thought I would like to know so I can check student M. (Yep-for real)
Today I had a teacher email me about student Q, R, S, and T concerned about student X's head lice that they all saw crawling in her hair. Teacher does not have student X as a student, but thought I might like to know.
What do you do when you get a 3rd party report of head lice? Do you call the "affected" student down for a check? What do you tell the student? Sometimes it feels a bit like a witch hunt to me, but I am curious what other nurses do.
