Head Lice   

arrow Previous bar Next arrow

To prevent the spread of head lice infestations, school employees shall report all suspected cases of head lice to the appropriate staff designee. The nurse or staff designee shall examine the student and any siblings of affected students, members of the same household, and any additional students with which the affected student has come in very close contact. For students who have not been treated, if any live lice or nits (eggs) are found in the hair or on the scalp, the student shall be sent home by the end of the day from school and parents/guardians informed about recommended treatment procedures and sources of further information. These sources may include: "Recommendations for Treatment and Control," (Exhibit 1)

The Superintendent or staff designee shall send home notification or make contact by telephone to notify the parents/guardians of the student's exclusion until treatment is completed. (Education Code 48213 - informs parents of the reason for student's exclusion.)

Items at the school site, such as clothing, furniture, or carpeting, that may have been in contact with the head of the infected student, should be considered for treatment. Furniture and carpets need to be vacuumed and items that cannot be washed can be bagged in plastic for two weeks.

If there is one or more students affected in any class, the staff designee shall send an exposure notice, along with information about head lice, to all parents/guardians of all students in that class preschool or elementary, or at the appropriate grade level for middle school students. Staff may consider sub-groups of students who may have been exposed at other school-sponsored events (e.g. before/after school SMARTE programs, school sports, theatre, etc.) (Exhibit 2)

Students identified as having live lice or nits may return to school when:

1. They bring the completed and signed RECOMMENDATIONS FOR TREATMENT AND CONTROL OF HEAD LICE AND RELEASE FORM (Exhibit 1) from the parent/guardian verifying an FDA approved medicated treatment was used to treat the child.

2. Reexamination by the nurse or staff designee shows that all live lice have been removed after treatment.

A reexamination of the affected student should also occur 7-9 days after the child returns to school to ensure that no nits have hatched into live lice. If a student continues to have lice after treatment, he or she must be excluded from school until no evidence of live lice are noted.

To the best of their ability, staff shall at all times maintain the privacy of students that have been identified as having head lice and have been excluded from attendance.
