Head Lice

Last revised: November 25, 2022 

Head lice crawl from person to person by direct head to head contact. They do not spread disease. Anyone can get them. They are more common in children as their heads frequently touch when they play together. Itching is the main complaint. 

Let parents know if a child is suspected of having head lice or if someone in the class has head lice.

When a child is found to have head lice, he or she may remain at school. There is no medical reason for excluding a child with nits or live lice from school or child care. It is essential to handle the situation sensitively and to minimize any embarrassment to the child. The principal can send the Notice to Parents About Head Lice and the Head Lice Fact Sheet to parents of children in the classroom or daycare group where lice has been identified. A full course of treatment and avoiding close head-to-head activities are recommended.
