Learn the symptoms and treatment of viral gastroenteritis.</p> | <h2>What is viral gastroenteritis?</h2><p>Gastroenteritis is the inflammation of the stomach and small and large intestines. Viral gastroenteritis means the inflammation is caused by infection from a virus. It often causes <a href="/Article?contentid=746&language=English">vomiting</a> (throwing up), <a href="/Article?contentid=7&language=English">diarrhea</a> or both.</p><p>Viral gastroenteritis is often called "stomach flu," but it is not caused by the influenza virus. Viruses that cause viral gastroenteritis include rotaviruses, torovirus, adenoviruses, caliciviruses, astroviruses, and a group of Norwalk-like viruses.</p><h3>Viral gastroenteritis is NOT caused by any of the following, although the symptoms may be similar:</h3><ul><li>bacteria such as salmonella or E. coli </li><li>parasites such as Giardia </li><li>medications </li><li>other medical conditions </li></ul> | | <h2>Key points</h2><ul><li>Viral gastroenteritis is an infection of the stomach and intestines, caused by a virus.</li><li>The main symptoms include diarrhea and vomiting.</li><li>Diarrhea and vomiting can cause a loss of fluids, also called dehydration.</li><li>If dehydration is severe, patients may have to be given fluid intravenously (IV) at the hospital.</li><li>Viral gastroenteritis can spread by sharing food, water and utensils. Frequent hand washing can help prevent the spread of infection to others.</li><li>Viral gastroenteritis is usually not a serious illness. However, people who have weak immune systems are at risk for more serious infection.</li></ul> | | <h2>What are the symptoms of viral gastroenteritis?</h2><p>Diarrhea and vomiting are the main symptoms of viral gastroenteritis.</p><p>In addition to diarrhea and vomiting, a child with viral gastroenteritis may have the following symptoms. </p><ul><li>
<a href="/Article?contentid=30&language=English">Fever</a></li><li>Stomach cramps or a sore stomach</li><li>
<a href="/Article?contentid=29&language=English">Headache</a></li><li>Sore throat</li><li>Decreased activity level</li><li>Increased sleepiness</li><li>Decreased appetite </li></ul><p>In general, the symptoms begin one to two days after catching the virus. They can last for one to 10 days.</p> | <h2>Viral gastroenteritis can be spread</h2><h3>Viral gastroenteritis can spread through the following methods:</h3><ul><li>sharing food, water or eating utensils such as forks and knives with someone who has the virus</li><li>not washing hands after touching items that may have the virus on their surface</li><li>not washing hands after diaper changes or toileting</li></ul><p>It is important to clean and disinfect surfaces and items that your child touches, including toys, and wash laundry thoroughly to remove the virus from your home. </p><h2>Anyone can catch viral gastroenteritis</h2><p>People of all ages and backgrounds can get viral gastroenteritis. However, different groups often get different viruses:</p><ul><li>Babies and toddlers tend to get rotaviruses and torovirus more often. </li><li>Adenoviruses and astroviruses tend to cause diarrhea mostly in young children. </li><li>Norwalk-like viruses are more likely to cause diarrhea in older children and adults. </li></ul> | | | <h2>Treating viral gastroenteritis</h2><p>The best treatment for viral gastroenteritis in children and adults is to prevent <a href="/Article?contentid=776&language=English">dehydration</a>. Dehydration happens when more fluid leaves the body than enters it.</p><h3>Symptoms of dehydration include:</h3><ul><li>Dry, cracked lips and a dry or sticky mouth </li><li>Thirst </li><li>Low or no urine output; concentrated urine appears dark yellow </li><li>Not producing tears </li><li>Being fussy or cranky </li><li>Seeming bored or uninterested </li><li>Headache </li><li>Dizziness </li><li>Cramps </li><li>Chills </li><li>Fatigue </li></ul><h3>In severe cases, dehydration can cause:</h3><ul><li>Sunken eyes </li><li>Sunken fontanelle (soft spot) on the top of a baby's head </li><li>Nausea or vomiting </li><li>Irritability</li><li>Lethargy (little to no energy)</li></ul><p>If your child becomes severely dehydrated, they may need to be treated at the hospital. In the hospital, fluids can be replaced through an intravenous line (IV) if necessary. </p><h2>Viral gastroenteritis is rarely a serious illness</h2><p>For most people, viral gastroenteritis is not a serious illness. People who get viral gastroenteritis almost always recover completely without any long-term problems. How fast a child recovers from viral gastroenteritis partly depends on which virus is causing the illness.</p><p>Viral gastroenteritis can be a serious illness in people who are unable to drink enough fluids to replace what they lose through vomiting or diarrhea. Babies, young children, and people who are unable to care for themselves, such as the disabled or elderly, are at risk for dehydration from losing too much of the body's water.</p><p>People with immune system problems are at risk for dehydration because they may get more severe symptoms, including more vomiting and diarrhea. People with severe symptoms may need to stay in the hospital to treat or prevent dehydration.</p> | | | <h2>You can prevent viral gastroenteritis with good hand washing</h2>
<h3>To avoid catching or spreading viral gastroenteritis, you should do the following things:</h3>
<ul>
<li>Wash hands well and often. This is especially important at hospitals and other medical facilities. </li>
<li>Do not visit anyone in hospital when you are ill with symptoms of viral gastroenteritis. Ask other family members and friends to do the same. </li>
</ul> | <h2>If your child is in hospital, help stop viral gastroenteritis from spreading</h2><ul><li>Your child may be placed in a single room and will not be able to visit the playroom until they are feeling better. </li><li>Wash your hands often before and after touching your child and before leaving your child's room. Expect hand washing by hospital staff as well. </li><li>If you or anyone else who has visited becomes ill with symptoms of viral gastroenteritis, let your child's doctor or nurse know.</li><li>If your child has symptoms of viral gastroenteritis and they are in the hospital, all staff caring for your child should wear gloves and a gown. </li></ul> | | | | | | | | | | | | | | | | | | | <img alt="" src="https://assets.aboutkidshealth.ca/AKHAssets/viral_gastroenteritis_flu.jpg" style="BORDER:0px solid;" /> | https://assets.aboutkidshealth.ca/AKHAssets/viral_gastroenteritis_flu.jpg | stomachflu | | | | | | Viral gastroenteritis (stomach flu) | | False | | | | | |
