Head lice are minute parasitic insects that inhabit the human head, especially hairs, and feed on minute amounts of blood drawn from the scalp. Head lice are wingless insects that append to the scalp and spread from one child infested with them to another by means of direct contact. Often known to be a bane for parents, invasion of head lice, medically known as ‘pediculosis', is not related to the hygiene of an individual, but is concerned with proximity. For instance, two children having their heads touching one another's while working on a project, sharing a book, wrestling or playing a video game, lice can be transmitted from the head of the infested child to the other, who is free from this parasitic insect. It may be noted that even if a single child in a class is infested with lice, it is possible that all the children in the class may also be infested by the insect sooner or later. In addition, any child attending a summer camp is especially vulnerable to infestation by head lice provided any of the cabin mates also has head lice. Apart from direct contact, lice have the aptitude to spread very simply by means of sharing combs, clothing, hats, pillows, sheets and hair brushes.
In case your child has been complaining of a uncomfortable head or if you observe them scraping their head relentlessly, it is advisable that you examine their scalp closely. If you fail to notice anything on her scalp under the normal light, use a flashlight to enable you to see better. Head lice have the appearance of minute encircling greying protuberances on the scalp. If you examine closely you may possibly see eggs, called nits, on the length of the hair shaft. Examine the lymph nodes (diminutive oval-shaped appendage of the immune system) in the neck of your child as well as at the backside of her head. The lymph nodes may become enlarged if the child scratches them resulting in a secondary infection.
It has been found that the female lice lay as many as four to five eggs daily and keep on doing it unless the process is stopped by applying some aggressive treatment. In the event of your child being infested by head lice, you ought to inform the authorities at her school, camp and all other public or community areas from where she might have contacted the infestation or, alternately, transmitted the parasite to other children. In order to help your child from being infested with head lice once she has been treated of the menace, it is important to undertake a quick and meticulous cleaning of the community.
Precisely speaking, head lice are really very uncomfortable and may result in relentless irritation. Owing to persistent scratching, the scalp of your child may become raw and result in an infection, such as impetigo, making matters worse. Therefore, when you are combing or washing your child's hair, look for warnings or symptoms of any localized infection.
Although head lice are extremely minute, it is possible to see the parasite even with naked eyes. What you or your healthcare provider is able to see on close examination of the child's scalp is discussed in brief below.
Lice eggs (also known as nits): The eggs of lice are minute and have the appearance of yellow, tan or brown specks prior to being hatched. Generally, lice lay their eggs on the hair shaft near to the scalp - the temperature at this place is ideal to keep the eggs warm till they are hatched. Nits have an appearance that is somewhat akin to dandruff, the only difference being that one cannot get rid of them by brushing or shaking them of the head.
Except for a heavy infestation of head lice, one can generally see the nits in the hair of a child instead of seeing the live lice creeping on the child's scalp. Normally, the hatching period for lice eggs is one to two weeks from the time they are laid. When the eggs are hatched and the lice come out of their shell, the shell has a white or clear appearance and still remains firmly stuck to the hair shaft. In fact, when the shells stick to the hair shaft after the eggs are hatched, it is easiest to notice them. This is primarily owing to the fact that as the hair grows in length, the shells stuck on the hair shaft move more further from the scalp.
Adult lice and nymphs (baby lice): Generally, an adult louse (singular for lice) is approximately of the size of a sesame seed and has a greyish-white or tan color. The nymphs or baby lice are normally much smaller in size and turn into adult lice after around one or two weeks following the time they are hatched. Majority of the lice survive on small amounts of blood drawn from the scalp several times every day. However, it has been found that lice are also able to live for as many as two days remaining off the scalp.
Scratching: When a child is infested with head lice, it becomes very uncomforting and she begins to scratch to get relief from the itching on the scalp. The itching actually occurs owing to an effect of the saliva released by lice. Nevertheless, the itching may not begin right from the first day of having head lice, but largely depends on the extent of whether the child's skin is sensitive or susceptible to lice. At times, it may take a number of weeks for a child having head lice to begin scratching her scalp. Normally, children having head lice complain of things crawling about on their scalp resulting in an irritating sensation on the scalp.
Tiny, red lumps or sores due to scratching: In case of some children infested with head lice, the irritation is gentle, while many others may experience appearance of a more annoying rash on the scalp. In addition, too much scratching may also result in bacterial infection and in such cases, the skin on the scalp would turn red and sore and may also have flaking and seeping accompanied by distended lymph glands. In the event of your doctor diagnosing the case as a bacterial infection, he may prescribe oral antibiotics to treat the condition.
In addition, when you closely check the scalp of your child you may also be able to observe the lice or the tiny nits by splitting the hair of your child into little sections. In addition, you may also part her hair and look for lice and nits using a fine-toothed comb on her scalp, at the back of the ears and also in the region of the nape. It is, however, very unlikely to find lice or nits on the eyelashes or eyebrows of children infested with head lice. If you are unable to see properly under normal light, use a microscope and a bright light to examine in a better manner. However, it may be quite tricky to detect an adult louse or a nymph because they usually have the ability to move very fast and you generally would not find many of them around.
You may try different home remedies to treat head lice, but there may be occasions when you might require calling your doctor. For instance, you ought to call your doctor if you notice that your child is relentlessly scratching his/ her hear or whine about a tickly/ scratchy scalp that is somewhat obdurate. Once the doctor examines the scalp of your child, he would be in a position to confirm whether your child has been infested with head lice and requires some kind of treatment. However, every child does not have the typical symptoms of having head lice and many of them may even be completely free from any type of symptom.

In fact, these horrible minute parasitic bugs can cause problems for children of all ages, societies and economic levels around the world, irrespective of how frequently they clean their hair or take a bath.

In addition, also inform your children that they should not lie down on pillows, beddings and carpets that have been used by any individual having lice.
