Reduce the Risk of Head Lice Transmission
Reduce the Risk of Head Lice Transmission
Head lice commonly affects school-aged children, although may be
transmitted to any age group. Also known as pediculus humanus capitis,
this parasite survives on human blood and usually is found on the
scalp, behind the ears, or on the back of the neck. With the upcoming
school year approaching, this is a good time to review the signs of a head
lice infestation, as well as the ways to prevent transmission. Itchiness,
sores, and irritability may all be warning signs of lice infestation. If this is
suspected, look closely through the hair and scalp for crawling lice, which
will require treatment.
Transmission risk is greatest when close contact occurs with an infested
person. Head lice may also be acquired through contact with clothing
or other personal items of a person with an infestation. Items such as
brushes, stuffed animals, or hats are all potential vehicles for head lice
transmission. For school children, it is best to avoid sharing these personal
items to decrease the risk of acquiring head lice. Personal hygiene
and home or school cleanliness do not correlate with increased infestation
risk.
