Head Lice: How To Check
You can see head lice easily although they are pretty small. An adult louse is sort of brown and is about the size of a sesame seed. Once they hatch, louse nymphs reach adulthood in about a week. Lice need to feed about every four or six hours and can live independent of the scalp for as much as three days.
After lice bite, you get the urge to itch or scratch, although the itchiness won't necessarily begin right away. This is dependent upon how sensitive your skin is to head lice. You can see lice by parting the hair a little bit at a time. When you are looking for lice, you should check the scalp, the area behind the ears, and near the nape of the subject's neck.
It is helpful to search for lice using a magnifying glass, lice comb and bright light. It is, however, tough to find a nymph or adult louse. A lot of times, there aren't loads of of them but they're able to move fast so it becomes difficult to find them.
Head lice can jump from person to person extremely quickly. The little bugs are extremely contagious in groups that have close contact. Even though the small lice can't fly and have difficulty jumping, they have developed special claws that allow them to cling firmly in hair. Sharing personal items; such as cloths, linens, combs, and brushes; encourage the spread of the bugs.
The lice and nits can be killed using medicated lice treatments. Itching will take some days to stop. It is suggested to repeat the treatment in 8 to 10 days to make sure all the nits have been killed, to avoid any possibility of getting them again.
The numbers of body lice are growing around the world. These small disease transmitters can carry typhus, fever, and trench fever. However, body lice are more embarrassing and itchy than life threatening. During the winter season, the lice become more common as people dress in thicker layers of clothes. These layers are warm, moist areas that promote lice growth. Usually, body lice are limited to countries with bad sanitation and overcrowding.
Head lice mature in a week, feeding on blood at least four times a day, but able to fast up to 3 days. Locate behind ears, back of the neck, and top of the head, using bright light and a magnifying glass. Part the hair in tiny sections, using a lice comb. Casual contact and sharing personal grooming transmits the head louse. Bites cause irritation quickly in sensitive skin. Medicated lice treatments are effective if repeated in 8 to ten days to break the insect breeding cycle. Warm moist conditions, overcrowding and lack of sanitation promotes the spread of body lice, spreading fevers such as typhus in developing countries.
