No-nit policies in schools: time for change.
No-nit policies that exist in many schools throughout the United States were established years ago based on fear and misinformation, rather than scientific evidence. Children who are found to have live lice are no more infectious on the day of diagnosis than they had been prior to the discovery. Transmission of head lice requires close personal contact, which is not common in the school setting. To date, no scientific literature exists to support the exclusion of children from school due to head lice infestation. Therefore, there is a need to develop updated school policies using research-based evidence to determine the best method of treating infestations while allowing children to remain in school.
