Head lice are tiny insects that live on the scalp, where they lay eggs (nits). Head lice do not spread disease. It is not your fault if you or your child has head lice. Having head lice does not mean you are not clean. Head lice spread easily, especially where people are in close contact. They are very common among school-aged children or children in childcare.

Should one go to childcare, school, or work if they have head lice? |
|
Those with head lice should be treated and then attend school, childcare, or work as usual. Consult with your school, childcare, or work policy. No-nit policies are discouraged by both the Canadian Pediatric Society and the American Academy of Pediatrics. Teach your child to avoid head-to-head contact. Children should not share combs, hairbrushes, tuques, hats, or hair accessories. Note: The Health Unit does not provide clearance to return to school, childcare, or work. The Health Unit does not perform head checks for lice. |
