From Dr. Richard Loyd. Rotavirus is a genus of double-stranded RNA viruses in the family Reoviridae. Rotaviruses are the most common cause of diarrhoeal disease among infants and young children. Nearly every child in the world is infected with a rotavirus at least once by the age of five.Encyclopedia Entry for Rotavirus :Rotavirus infections - Rotavirus (reovirus)Encyclopedia Entry for Rotavirus :Rotavirus antigen test. There are many ways to collect stool samples. You can catch the stool on plastic wrap that is loosely placed over the toilet bowl and held in place by the toilet seat. Then you put the sample into a clean container. One type of test kit supplies a special toilet tissue to collect the sample, which is then placed in a container. For infants and young children wearing diapers, line the diaper with plastic wrap. Position the plastic wrap to prevent urine and stool from mixing in order to get a better sample. The sample should be collected while the diarrhea is occurring. Take the sample to the lab to be checked.No special preparation is necessary for this test.The test involves normal defecation.Rotavirus is the leading cause of gastroenteritis ('stomach flu') in children. This test is done to diagnose a rotavirus infection.Normally, rotavirus is not found in the stool. Note: Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your health care provider about the meaning of your specific test results.Rotavirus in the stool indicates a rotavirus infection is present.There are no risks associated with this test.Because rotavirus is easily passed from person to person, take these steps to prevent the germ from spreading: Wash your hands well after contact with a child who could be infected. Disinfect any surface that has been in contact with stool. Ask your provider about a vaccine to help prevent severe rotavirus infection in children under 8 months old. Watch infants and children who have this infection closely for signs of dehydration.Gastroenteritis - rotavirus antigen.Fecal sample Fecal sample.Bass DM.

Rotavirus is a virus that causes diarrhea, mostly in babies and young children. The diarrhea can be severe, and lead to dehydration. Vomiting and fever are also common in babies with rotavirus. Before rotavirus vaccine, rotavirus disease was a common and serious health problem for children in the United States. Almost all children in the United States had at least one rotavirus infection before their fifth birthday. Every year before the vaccine was available: More than 400,000 young children had to see a doctor for illness caused by rotavirus More than 200,000 had to go to the emergency room 55,000 to 70,000 had to be hospitalized 20 to 60 died Since the introduction of the rotavirus vaccine, hospitalizations and emergency visits for rotavirus have dropped dramatically. ROTAVIRUS VACCINE Two brands of rotavirus vaccine are available. Your baby will get either 2 or 3 doses, depending on which vaccine is used. Doses are recommended at these ages: First dose: age 2 months Second dose: age 4 months Third dose: age 6 months (if needed) Your child must get the first dose of rotavirus vaccine before age 15 weeks, and the last dose by age 8 months. Rotavirus vaccine may safely be given at the same time as other vaccines. Almost all babies who get rotavirus vaccine will be protected from severe rotavirus diarrhea. And most of these babies will not get rotavirus diarrhea at all. The vaccine will not prevent diarrhea or vomiting caused by other germs. Another virus called porcine circovirus (or parts of it) can be found in both rotavirus vaccines. This is not a virus that infects people, and there is no known safety risk. SOME BABIES SHOULD NOT GET THIS VACCINE A baby who has had a life-threatening allergic reaction to a dose of rotavirus vaccine should not get another dose. A baby who has a severe allergy to any part of rotavirus vaccine should not get the vaccine. Tell your doctor if your baby has any severe allergies that you know of, including a severe allergy to latex. Babies with 'severe combined immunodeficiency' (SCID) should not get rotavirus vaccine. Babies who have had a type of bowel blockage called 'intussusception' should not get rotavirus vaccine. Babies who are mildly ill can get the vaccine. Babies who are moderately or severely ill should wait until they recover. This includes babies with moderate or severe diarrhea or vomiting. Check with your doctor if your baby's immune system is weakened because of: HIV/AIDS, or any other disease that affects the immune system Treatment with drugs such as steroids Cancer, or cancer treatment with x-rays or drugs RISKS OF A VACCINE REACTION Like any medicine, when getting a vaccine, there is a chance of side effects. These are usually mild and go away on their own. Serious side effects are also possible, but are rare. Most babies who get rotavirus vaccine do not have any problems with it. But some problems have been associated with rotavirus vaccine. Mild problems following rotavirus vaccine: Babies might become irritable, or have mild, temporary diarrhea or vomiting after getting a dose of rotavirus vaccine. Serious problems following rotavirus vaccine: Intussusception is a type of bowel blockage that is treated in a hospital, and could require surgery. It happens 'naturally' in some babies every year in the United States, and usually there is no known reason for it. www.cdc.gov/vaccines/hcp/vis/vis-statements/rotavirus.pdf Problems that could happen after any vaccine: Any medication can cause a severe allergic reaction. Such reactions from a vaccine are very rare, estimated at fewer than 1 in a million doses, and usually happen within a few minutes to a few hours after the vaccination. As with any medicine, there is a very remote chance of a vaccine causing a serious injury or death. The safety of vaccines is always being monitored. For more information, visit: www.cdc.gov/vaccinesafety. WHAT IF THERE IS A SERIOUS PROBLEM? What should I look for? For intussusception, look for signs of stomach pain along with severe crying. Early on, these episodes could last just a few minutes and come and go several times in an hour. Babies might pull their legs up to their chest. Your baby might also vomit several times or have blood in the stool, or could appear weak or very irritable. These signs would usually happen during the first week after the first or second dose of rotavirus vaccine, but look for them any time after vaccination. Look for anything else that concerns you, such as signs of a severe allergic reaction, very high fever, or unusual behavior. Signs of a severe allergic reaction can include hives, swelling of the face and throat, difficulty breathing, or unusual sleepiness. These would usually start a few minutes to a few hours after the vaccination. What should I do? If you think it is intussusception, call a doctor right away. If you can't reach your doctor, take your baby to a hospital. Tell them when your baby got the rotavirus vaccine. If you think it is a severe allergic reaction or other emergency that can't wait, call 9-1-1 or take your baby to the nearest hospital. Otherwise, call your doctor. Afterward, the reaction should be reported to the Vaccine Adverse Event Reporting System (VAERS). Your doctor might file this report, or you can do it yourself through the VAERS web site at www.vaers.hhs.gov , or by calling 1-800-822-7967. VAERS does not give medical advice. THE NATIONAL VACCINE INJURY COMPENSATION PROGRAM The National Vaccine Injury Compensation Program (VICP) is a federal program that was created to compensate people who may have been injured by certain vaccines. Persons who believe they may have been injured by a vaccine can learn about the program and about filing a claim by calling 1-800-338-2382 or visiting the VICP website at www.hrsa.gov/vaccine-compensation/index.html. There is a time limit to file a claim for compensation. HOW CAN I LEARN MORE? Ask your doctor. Your health care provider can give you the vaccine package insert or suggest other sources of information. Call your local or state health department.
