Even though lice are not a major threat to health, they are a frustrating nuisance and easily spread. There are many ways to treat head lice, but no one way works all the time.
Some lice are resistant to commonly used pediculicides.
In order to prevent outbreaks in the school setting, the following procedure must be established at each site. When a student is initially identified as having head lice, the student will be excluded from school immediately for treatment. At the time of treatment parents are provided with information regarding treatment of the infestation. It is the position of the National Association of School Nurses that nit-free policies disrupt the education process and should not be viewed as an essential strategy in the management of head lice. The student cannot be re-admitted if live lice are still present.
