Infant lice infestation: Understanding lice biology, research findings, and more
Head Lice: A Common Concern Among Young Children
Head lice are a common issue affecting children, particularly those in elementary school, preschool, and childcare settings, as well as family members living in the same household as an infected child. This small parasitic insect, about the size of a sesame seed, can be a source of discomfort and anxiety for both children and their parents.
Understanding the Life Cycle of Head Lice
The life cycle of a head louse comprises three stages: nit, nymph, and adult. Female lice lay their eggs, known as nits, one to two days after mating. Nits are oval and about 0.8 by 0.3 millimeters in size, often white or dull yellow, but they may also appear to be the same color as a person's hair. Nymphs hatch from nits and are about the same size as a pinhead, resembling adult lice but smaller.
Symptoms and Preventive Measures
Symptoms of lice in infants and toddlers primarily include persistent scalp itchiness and scratching, especially behind the ears and at the nape of the neck. The itchiness may not appear immediately after infestation, sometimes taking 4 to 6 weeks to develop. Other signs include finding live lice or their eggs (nits) attached close to the scalp.
Preventive measures for lice in infants and toddlers focus on avoiding direct head-to-head contact with others who may have lice and not sharing personal items that touch the hair. These items include hats, scarves, combs, brushes, hair accessories, headphones, pillows, towels, stuffed animals, and fabric furniture coverings. Regularly checking the child's hair, especially after overnight stays or playdates, can help early detection. Educating children about avoiding sharing head-related items also helps reduce transmission.
| Symptoms | Preventive Measures | |--------------------------------------|---------------------------------------------------------------------------| | Persistent scalp itching and scratching (behind ears, nape of neck) | Avoid head-to-head contact | | Presence of live lice or nits (eggs) near the scalp | Do not share hats, combs, brushes, hair accessories, or pillows | | Itching may take several weeks to start | Inspect child’s hair weekly and after close contact with others | | Possible irritability or sleeplessness due to itching | Educate children to avoid sharing personal hair items |
Dealing with an Infestation
If an infestation is confirmed, it is recommended to wash all clothes, bedsheets, and other washable items a person with lice has used in the 2 days before lice treatment on a hot laundry and dryer cycle. Alternatively, tightly sealing these items in a plastic bag for 2 weeks can also prevent lice. Drycleaning pillows, stuffed toys, and other nonwashable items a person with lice has used in the 2 days before lice treatment is another prevention method. Vacuuming beds, carpets, mats, and furniture where someone with lice has sat or laid down can help prevent lice. A healthcare professional can help identify lice and advise which lice treatment may work best for an individual.
Early and accurate identification combined with preventive hygiene and behavior measures are essential to control lice in young children.
