A parasite cannot live by itself. Parasites include fleas, <a href="https://akhpub.aboutkidshealth.ca/article?contentid=795&language=English">lice</a> and worms. Parasitic diseases include infections by protozoa (single-cell organisms such as malaria), helminthes (worms) and arthropods (such as <a href="/Article?contentid=797&language=English">scabies</a>).</p><h2>Key points</h2> <ul><li>An intestinal parasite will live in the intestine or other parts of the body and often reproduce. </li> <li>Poor sanitation and unsafe water increase the risk of catching intestinal parasites. </li> <li>For children who do get sick, symptoms may include watery diarrhea, tiredness, and nausea. </li> <li>Treatment may include oral medication. </li> <li>The best defence against parasites is good hygiene.</li></ul><h2>Giardiasis</h2><p>Giardiasis is a waterborne disease. Your child can catch the infection if they drink from a contaminated water source. Children are more likely to catch giardiasis in areas with inadequate water and sanitation facilities or places where many people are in close contact, such as child care centres.</p><p>Giardiasis is also known as beaver fever because it may be acquired from drinking untreated lake water. </p><h3>Signs and symptoms of giardiasis</h3><p>While some children may never develop signs or symptoms, they can still carry the parasite and spread it through their stool.</p><h3>For children who do get sick, symptoms may include:</h3><ul><li>watery <a href="/Article?contentid=7&language=English">diarrhea</a></li><li>soft, greasy stools </li><li>tiredness </li><li>stomach cramps</li><li>bloating</li><li>nausea</li><li>severe weight loss</li></ul><p>Blood and mucus in stool does not occur in giardiasis. Symptoms usually show about two weeks after infection. With treatment, the symptoms can improve in six weeks. Most children will never require treatment.</p><h3>Causes of giardiasis</h3><p>Its parasites can be found in rivers, streams, and lakes or municipal water supplies, swimming pools and spas. The infection can also be passed on through infected food or person-to-person contact. The parasites can also be found in animal feces.</p><h3>Potential complications of giardiasis</h3><p>Severe <a href="/Article?contentid=7&language=English">diarrhea</a>, which is quite rare, can lead to <a href="/Article?contentid=776&language=English">dehydration</a>.</p><h3>How giardiasis is diagnosed</h3><p>To find out if your child has giardiasis, your doctor will likely test your child's stool. Your child may have to repeat this test over a few days to ensure accuracy. </p><h3>Treating giardiasis</h3><p>There are some medicines used to treat the parasite. Your child's doctor will determine which treatments best suit your child's needs. </p><h2>Pinworm</h2><p>Pinworms are tiny, white, thread-like worms that live in the rectum. At night, the worm crawls out of the anus and lays eggs in nearby skin. This can cause a terrible itch. Pinworm can be unpleasant but it does not cause disease.</p><p>Pinworm eggs are very persistent. Pinworm eggs can live for up to two weeks outside the body, on clothing, bedding or other objects. </p><h3>Signs and symptoms of pinworm</h3><p>In general, children with pinworm do not usually have symptoms. They may get very itchy around the anus, especially at night. They may lose sleep. They may also be cranky from the irritation. </p><p>You may or may not see the adult worm around your child's anus, in underwear or diapers, or in the toilet after going to the bathroom.</p><h3>Causes of pinworm</h3><p>Pinworm can spread easily between children. When a child scratches an infected area, they get eggs on their fingers or under the fingernails. Transmission of the infection happens when the infected child passes the eggs to another child, and the child unknowingly swallows the eggs. </p><p>Pinworm can also be transmitted indirectly. Eggs from an infected person can stick to toys, toilet seats, clothes or bedding. A child will catch the infection when they touch the eggs and then put them in their mouth. Children are more likely to catch pinworms in milder climates and in child care centres.</p><h3>How pinworms are diagnosed</h3><p>To diagnose pinworms, the doctor may recommend a tape test to look for pinworm eggs. A tape test can be performed by you or your child's doctor. Cellophane tape is pressed against the skin around the anus. The tape is then examined under a microscope for pinworm eggs. If doing the test at home, it is best to do it in the morning before your child bathes or goes to the bathroom. Take the tape sample to your child's doctor.</p><p>Another way to test for pinworm is if you see the adult worm around your child's anus, in underwear or diapers, or in the toilet after going to the bathroom. Remember, they are white and only about a centimetre long. </p><h3>Treating pinworms</h3><p>If diagnosed, your child's doctor may prescribe an oral medication. The medicine usually takes about two weeks to work. The itching may continue for one week. </p><p>If one family member is diagnosed with pinworm, other family members should be examined and treated. </p><h2>Other common parasites in children</h2><h3>Blastocystis hominis</h3><p>Blastocystis hominis is a tiny parasite that is found in the stools of healthy or children with diarrhea or stomach pain. This infection usually clears up on its own. </p><h3>Dientamoeba</h3><p>Dientamoeba lives in the intestines. It is spread through infected food or water. Dientamoeba does not cause disease. </p><h3>Ascariasis</h3><p>Ascariasis (say: as-kuh-RI-uh-sis) is a type of roundworm infection. The worms can grow as long as 41 centimetres. This parasite is only serious when the body becomes infested with hundreds of worms. Your child will develop symptoms. </p><h3>Amebiasis</h3><p>Amebiasis occurs when amoeba get into your child's system and multiply. This infection may not show symptoms. Severe infection, which is rare, will lead to symptoms like fever, diarrhea, jaundice or weight loss. </p><h3>Tapeworm</h3><p>A tapeworm infection is caused by contaminated food or water. The swallowed tapeworm eggs move from your child's intestines to form cysts in body tissues and organs. Eaten tapeworm larvae can grow into adult tapeworms, which live in the intestine. </p><h2>When to seek medical assistance</h2> <h3>See your child's regular doctor if: </h3> <ul> <li>your child's diarrhea or nausea lasts longer than two weeks</li> <li>your child becomes dehydrated</li> </ul> <p>Be sure to tell the doctor if your child is in child care, has recently travelled to another country, or may have drunk contaminated water.</p>

Les moustiques, les puces et les vers sont des parasites. On peut citer à titre d'exemple de parasites les infections aux protozoaires (organismes unicellulaires comme la malaria), aux helminthes (vers), et aux arthropodes (comme <a href="https://akhpub.aboutkidshealth.ca/article?contentid=797&language=French">la gale</a>).</p><h2>À retenir</h2><ul><li>Un parasite intestinal vivra dans l’intestin ou d’autres parties du corps et, souvent, se reproduira. </li><li>Une mauvaise hygiène et de l’eau non potableaugmentent le risque d’attraper des parasites intestinaux. </li><li>Les enfants qui deviennent malades peuvent avoir des symptômes comme une diarrhéevraimentliquide, de la fatigue et des nausées. </li><li>Les médicaments orauxcomptent parmi les traitements. </li><li>De bonnes mesures d’hygiène sont le meilleur moyen de défense contre les parasites.</li></ul><h2>Giardiase</h2> <p>La giardiase est une maladie d’origine hydrique. Votre enfant peut attraper l’infection s’il boit de l’eau puisée d’une source contaminée. Les enfants sont plus susceptibles d'attraper la giardiase dans des endroits où les installations de traitement de l'eauet l'hygiène sont inadéquates, ou à des endroits où de nombreuses personnes sont en contact étroit, comme les garderies. </p> <p>La giardiase peut aussi être contractée en buvant l’eau non traitée d’un lac. </p> <h3>Signes et symptômes de la giardia​se</h3> <p>Si certains enfants peuvent ne jamais développer designes ou symptômes, ils peuvent tout de même être porteurs du parasite et le propager par les matières fécales.</p> <h3>Pour les enfants qui sont malades, voici les signes et sy​mptômes :</h3> <ul> <li><a href="https://akhpub.aboutkidshealth.ca/article?contentid=7&language=French">diarrhée</a> liquide;</li> <li>selles molles et graisseuses;</li> <li>fatigue; </li> <li>crampes à l’estomac;</li> <li>ballonnements;</li> <li>nausée;</li> <li>importante perte de poids.</li></ul> <p>Dans les cas de giardiase, on ne relève pas la présence de sang et de mucus. Les symptômes se manifestent habituellement environ 2 semaines après l'infection. Avec un traitement, les symptômes peuvent s'améliorer en 6 semaines. La plupart des enfants n'ont jamais besoin detraitement. </p> <h3>Causes de la ​giardiase</h3> <p>Ses parasites se trouvent dans les rivières, les ruisseaux et les lacs, ou encore l'eau de la municipalité, les piscines et les spas. L’infection se transmet aussi par des aliments contaminés ou un contact avec une personne infectée. Les parasites se trouvent aussi dans les déjections d'animaux. </p> <h3>Complications possiblesde la giardiase</h3> <p>Des <a href="/Article?contentid=7&language=French">diar​rhées</a> sévères, bien qu’assez rares, peuvent causer une <a href="/Article?contentid=776&language=French">déshydratation​</a>. </p><h3>Comment diagnostiquer la giardiase</h3> <p>Pour savoir si votre enfant a la giardiase, votre médecin analysera probablement les selles de votre enfant. Il pourrait avoir à repasser le test sur plusieurs jours par souci deprécision. </p> <h3>Traiter la giardia​se</h3> <p>Certains médicaments peuvent combattre le parasite. Le médecin de votre enfant déterminera les traitements qui conviennent le mieux à votre enfant. </p> <h2>Oxyures</h2> <p>Les oxyures sont des vers minces et blancs qui vivent dans le rectum. La nuit, le ver rampe hors de l’anus et pond ses œufs dans de la peau à proximité. Cela peut causer de graves démangeaisons. Les oxyures sont déplaisants, mais ne causent pas de maladie. </p> <p>Par contre, les oeufs sont très persistants. Les œufs peuvent en effet vivre jusqu’à 2 semaines à l’extérieur de l’organisme, sur les vêtements, dans la literie ou sur d’autres objets. </p> <h3>Signes et sym​ptômes de la présence d’oxyures</h3> <p>En général, les enfants qui portent ce ver n’ont pas de symptômes. Ils pourraient avoir d'importantes démangeaisons autour de l'anus, surtout la nuit. L'enfant pourrait perdre du sommeil et être irrité facilement à cause des démangeaisons. </p> <p>Vous pourriez ou non apercevoir le ver adulte autour de l'anus de votre enfant, dans ses sous-vêtements ou ses couches, ou dans la cuvette destoilettes après utilisation.</p> <h3>Causes des ox​yures</h3> <p>Les oxyures se transmettent très facilement chez les enfants. Quand l'enfant gratte le site infecté, les oeufs s'accumulent sous les ongles. Les oeufs sont transmis quand l'enfant infecté transfère les oeufs à un autre enfant, et que l'enfant avale les oeufs par inadvertance. </p> <p>Les oxyures peuvent aussi être transmis indirectement. Les œufs provenant d’une personne infectée peuvent se déposer sur des jouets, des sièges de toilette, les vêtements ou la literie. Un enfant attrapera l'infection s'il touche aux oeufs et les met dans sa bouche. Les enfants sont plus enclins à attraper des oxyures s'ils vivent dans des climats chauds et dans des centres de garde. </p> <h3>Comment établi​t-on le diagnostic</h3> <p>Pour diagnostiquer les oxyures, le médecin pourrait recommander de faire une analyse d'un échantillon. Le médecin de votre enfant ou vous-même pouvez prélever l'échantillon en collant du ruban transparent autour de l'anus. On examine ensuite le ruban sousun microscope. Si vous faites le test à la maison, mieux vaut prélever l'échantillon le matin avant que votre enfant ne se lave ou aille à la salle de bains. Apportez l'échantillon chez le médecin. </p> <p>Si vous voyez le ver adulte autour de l’anus de votre enfant ou dans sa couche, ou encore dans la cuvette des toilettes, le diagnostic peut être posé à ce moment. N'oubliez pas, les vers sont blancs et mesurent à peine environ un centimètre. </p> <h3>Traitement​</h3> <p>Si le médecin confirme le diagnostic, il prescrira un médicament oral. Il fautenviron2semaines aumédicament pourfaire effet. Les démangeaisons, elles pourraient continuer pendant une semaine.</p> <p>Si un membre de la famille reçoit le diagnostic, les autres membres de la famille devraient passer le test de dépistage et prendre le traitement. </p> <h2>Autres parasites courants chez les enfants</h2> <h3>Blastocystis hominis</h3> <p>Le Blastocystis hominis est un petit parasite que l’on trouve dans les selles d'enfants sains ou d’enfants atteints de diarrhée ou de douleurs à l’estomac. Cette infection disparaît habituellement toute seule. </p> <p>Dientamoeba vit dans les intestins. Elle se propage par lesaliments ou l’eau infectés. Elle ne cause pas de maladie. </p> <h3>Ascaridiose </h3> <p>L’ascaridioseest un type d’infection par un ver rond (nématode). Les vers peuvent mesurer jusqu’à 41 centimètres de longueur. Ce parasite n’est dangereux que si le corps est infecté par des centaines de vers. Votre enfant aura des symptômes. </p> <h3>Amibiase</h3> <p>L’amibiase survient quand des amibes pénètrent dans le système de votre enfant et se multiplient. Cette infection pourrait engendrer ou non des symptômes. Une grave infection, qui demeure rare, entraînera des symptômes comme de la fièvre, une diarrhée, la jaunisse ou la perte de poids. </p> <h3>Ver solitaire (Ténia)</h3> <p>Une infection au ver solitaire est causée par des aliments ou de l’eau contaminés. Les oeufs avalésse déplacent des intestins de l'enfant pour former des kystes dans des tissus et des organes. Les larves ingérées peuvent se développer en vers solitaires adultes, qui vivent dans les intestins. </p><h2>Quand consulter un médecin</h2> <h3>Consulter le médecin de l’e​nfant si : </h3> <ul> <li>la diarrhée ou la nausée durent plus de 2 semaines;</li> <li>votre enfant se déshydrate.</li></ul> <p>Assurez-vous de mentionner au médecin si votre enfant fréquente une garderie, s’il a récemment voyagé dans un autre pays ou s’il se peut qu'il ait bu de l'eau contaminée. </p>

Remember, they are white and only about a centimetre long. </p><h3>Treating pinworms</h3><p>If diagnosed, your child's doctor may prescribe an oral medication. The medicine usually takes about two weeks to work. The itching may continue for one week. </p><p>If one family member is diagnosed with pinworm, other family members should be examined and treated. </p><h2>Other common parasites in children</h2><h3>Blastocystis hominis</h3><p>Blastocystis hominis is a tiny parasite that is found in the stools of healthy or children with diarrhea or stomach pain. This infection usually clears up on its own. </p><h3>Dientamoeba</h3><p>Dientamoeba lives in the intestines. It is spread through infected food or water. Dientamoeba does not cause disease. </p><h3>Ascariasis</h3><p>Ascariasis (say: as-kuh-RI-uh-sis) is a type of roundworm infection. The worms can grow as long as 41 centimetres. This parasite is only serious when the body becomes infested with hundreds of worms. Your child will develop symptoms. </p><h3>Amebiasis</h3><p>Amebiasis occurs when amoeba get into your child's system and multiply. This infection may not show symptoms. Severe infection, which is rare, will lead to symptoms like fever, diarrhea, jaundice or weight loss. </p><h3>Tapeworm</h3><p>A tapeworm infection is caused by contaminated food or water. The swallowed tapeworm eggs move from your child's intestines to form cysts in body tissues and organs. Eaten tapeworm larvae can grow into adult tapeworms, which live in the intestine. </p><h2>Prevention</h2> <p>The best defence against parasites is good hygiene.</p> <h3>Your child, your family and your child's day care should adopt these healthy habits:</h3> <ul> <li>Wash hands frequently, especially after changing diapers, going to the bathroom and playing outside.</li> <li>Potentially contaminated water should be avoided, or boiled or filtered.</li> <li>Wash bedding regularly.</li> <li>Wash children's toys with disinfectant.</li> <li>Change underwear regularly.</li> <li>Try not to swallow water while swimming in pools, lakes or streams.</li> <li>Since pinworm eggs are sensitive to light, open blinds or curtains in bedrooms during the day.</li> </ul><h2>When to seek medical assistance</h2> <h3>See your child's regular doctor if: </h3> <ul> <li>your child's diarrhea or nausea lasts longer than two weeks</li> <li>your child becomes dehydrated</li> </ul> <p>Be sure to tell the doctor if your child is in child care, has recently travelled to another country, or may have drunk contaminated water.</p><img alt="" src="https://assets.aboutkidshealth.ca/AKHAssets/intestinal_parasites.jpg" style="BORDER:0px solid;" />https://assets.aboutkidshealth.ca/AKHAssets/intestinal_parasites.jpgIntestinal parasites
