I understand there are some students at my child's school who have head lice, but they weren't sent home to be treated. Shouldn't they be treated before returning to class?
School nurses often answer questions about head lice, and help parents understand the common myths about how they are spread. Classroom transmission is extremely rare, so notes are not sent home with students unless a large number of students in the same class have head lice. Sending a note home with all students in a classroom can cause unnecessary panic among parents, even leading to treating unaffected children with potentially harmful substances when no lice are present. Our school nurses will work with individual families to identify close contacts of the affected students. Research shows that head lice can only be spread by head-to-head contact, which is not common in school.
