Pediculus Humanus Capitis
Are you itching yet?
Head lice is the most prevalent human parasitic infestation
Estimated 6 to 12 million cases in the US each year in children 3-11 years of age
That is about 1 in 100 elementary school students or approximately 25% of an elementary school
Head Lice infest people of all ages but most occur among school age children, their household members and care takers
Lice are wingless insects that live close to the human scalp
They feed on human blood
They move by crawling and are most often spread by direct head to head contact
How do I look?
The eggs, also called nits are tiny, teardrop shaped eggs that attach to the hairshaft
Nits appear yellowish or white and can be mistaken for dandruff
Sign and Symptoms of Head Lice Infestation
Tickling feeling on the scalp or in hair
Itching (caused by bites of louse)
Irritability & difficulty sleeping (yep those buggers are nocturnal)
Sores on the head
skin excoriated from scratching can lead to a secondary bacterial infections
First, take a deep breath, lice is not a life threatening situation!!
What do I do??
If you suspect a child has lice encourage the parent to call their pediatrician for proper care
There are OTC head lice treatments as well as prescription treatments
Nits will need to be manually combed out of the hair
Separate hair into small sections
Use a "nit comb"- fine tooth metal or plastic comb to remove nits from hair shaft
Repeat this process at least every two days for 12 to 14 days
Guidelines from the CDC
All persons who receive treatment should be treated simultaneously
Lice products should be used with care and only as directed. Patients should be cautioned not to use extra amounts of lice medication and not to use different lice medications at the same time unless told to do so by health care professional
If live lice are visible after treatment has been completed, patient should contact their health care provider.
