Head Lice - A Lousy Problem
Head Lice - A Lousy Problem
2. The head louse and the body louse are physically indistinguishable, but are easily distinguished from the crab louse. Head lice (also known as "head louse") are small insects that live in people's hair and feed on their blood.
3. Lice glue their eggs (also known as "nits") to hair so they cannot be brushed or shaken off easily. Lice eggs take about six to nine days to hatch. After they have hatched they take about seven or more days to become egg-laying adults.
4. Lice die very quickly (usually about two days) without feeding and cannot live for very long away from a person's head.
5. They need blood to survive and can live up to 30 days on the head but will die within 1-2 days if they fall off the head.
6. Head lice is also called pediculosis.
8. Head lice can be a bother because of the discomfort they can cause and how easily they are spread from person to person.
99. Head lice are not caused by being dirty. Anyone who has hair can get head lice.
10. Head lice can move quickly on dry hair making them hard to see.
11. Head lice do not jump or fly or swim.
12. Head lice bites can make the scalp itchy but they do not cause disease.
13. Adult head lice lay about 10 eggs (called nits) every day. These nits are stuck to the hair near the scalp. After the head lice hatch, the empty shell of the nit stays stuck to the hair.
15. You can find lice anywhere on the head. Look behind the ears and the back of the neck.
16. Lice can vary in colour from tan, brown or gray.
17. You cannot get rid of lice with a hair brush or with a hair dryer.
18. You can get head lice by touching heads with someone who has head lice, or by sharing combs, brushes, hats, headsets or helmets.
19. Head lice are common where children play or work closely together.
20. The best way to find head lice is by using a fine toothed lice comb on hair that is dry, wet or wet with conditioner.
21. Only treat when you find a live louse on the head.
22. Pets cannot get head lice and people cannot get head lice from pets.
23. Head to head contact with someone who has head lice.
24. Sharing things that are in direct contact with a person’s hair such as combs, brushes, barrettes, ribbons, caps, hats, scarves, helmets, towels, pillows and coats.
25. Children age 5 to 12 get lice more easily because their heads often touch when they play together.
26. Combing with a nit comb-A nit comb can sometimes be effective in removing viable nits and lice. Nits that are more than ¼ inch from the scalp are not likely to be viable and need not be removed. Comb daily until no live lice are discovered for 2 weeks. Recheck in 2-3 weeks after you think all lice are gone.
27. Over-the-counter lice shampoo-As with all drugs, directions must be followed exactly. These products should be rinsed from the hair over a sink rather than shower or bath to limit exposure to the body. A second treatment may be required in about 10 days.
288. Prescription lice shampoo medications-These products contain other insecticides that require greater care for treatments and should be used only under a physician’s care and only if live lice persist following treatment with the over-the-counter products. Parents should be advised to discuss with their health care provider specific instructions for use of these products, potential risks and benefits, and other possible treatment recommendations.
29. A number of household products such as mayonnaise, petroleum jelly, olive oil, tea tree oil, hair gel and vinegar or wet combing have been suggested as a treatment. These products show little proof of killing head lice and are not as effective as head lice shampoo.
30.Wash clothing and bedding used in the last 3 days by the affected person in hot water and dry in a hot dryer.
31. Place items that cannot be washed in a sealed bag for two weeks.
32. Put all combs, brushes and hair accessories in hot, soapy water.
