The Broward School District says it is following recommendations from the American Association of Pediatrics, The National Association of School Nurses, and the Centers for Disease Control and Prevention.

There is no disease associated with head lice and in-school transmission is considered to be rare.

However, the Miami-Dade School Board policy has not been revised and states: “Any student found having head lice should be excluded from school until they are free of lice and have no nits.”

Head lice are not dangerous but they do require attention because they spread rapidly and are difficult to control.

About 10 million Americans get head lice each year.

Head lice live only in the hair and scalp and lay their eggs (nits) on the shafts of the hair near the scalp. Lice themselves are often difficult to see but the nits are small, whitish, teardrop shaped eggs, which can easily be seen with the naked eye.

Head lice are transmitted by:

  • Direct contact with an affected person’s head/hair. Lice cannot jump, leap, or fly!
  • Indirectly, by placing clothing of an affected child in contact with the clothing of an unaffected child.
  • Indirectly, by sharing such items as combs, brushes, hats, caps, scarves, wigs, pillows and bedding.

The signs and symptoms of head lice are: persistent itching behind the ears and at the nape of the

neck, restlessness or poor attention span and in severe cases, swollen lymph glands in the neck and

under the arms. As many as 50% of the students with head lice can be without symptoms; that is why
