Noroviruses - Topic Overview
What are noroviruses?
Noroviruses belong to a family of viruses that cause the "stomach flu." Noroviruses are also called Norwalk-like viruses and caliciviruses. Stomach flu is also called gastroenteritis, food infection, food poisoning, and acute nonbacterial gastroenteritis.
What causes infection with noroviruses?
Noroviruses generally spread through contaminated water and foods, although they can also pass from person to person. You may become infected by:
Eating food or drinking liquids that are contaminated with norovirus. Shellfish and salad ingredients are most often infected with the viruses. Food other than shellfish may be contaminated by food handlers.
Touching surfaces or objects contaminated with norovirus, and then placing your hand in your mouth.
Having direct contact with someone who is infected. For example, if you are a caregiver or share foods or utensils with someone who is ill, you may become infected.
Persons working in day care centers or nursing homes should pay special attention to children or residents who have norovirus illnesses. This virus is very contagious and can spread rapidly throughout these environments.
What are the symptoms?
The symptoms of gastroenteritis caused by the noroviruses include nausea, vomiting, diarrhea, and abdominal pain. Diarrhea and vomiting can cause dehydration. You may have a headache and fever of less than 100 F. A mild and brief illness usually develops 24 to 48 hours after you eat or drink the contaminated food or water and lasts for 24 to 60 hours. You are rarely very sick or have to go to the hospital.
How is infection with noroviruses diagnosed?
Since most norovirus infection is mild and passes in a few days, most people do not go to their health professionals for a diagnosis. You can often diagnosis food poisoning yourself if others who ate the same food as you also become ill.
If you do go to your health professional, he or she will make the diagnosis based on your symptoms, a medical history, and a physical exam. Your health professional will ask where you have been eating and whether anyone who ate the same foods has the same symptoms. A stool test or blood test is sometimes done.
How are infections with noroviruses treated?
You treat gastroenteritis caused by noroviruses by managing any complications until it passes. Dehydration caused by diarrhea and vomiting is the most common complication. Do not use medicines, including antibiotics and other treatments, unless your health professional recommends them.
To prevent dehydration, take frequent sips of a rehydration drink (such as Lytren, Rehydralyte, or Pedialyte). Try to drink a cup of water or rehydration drink for each large, loose stool you have. Sports drinks, soda pop, and fruit juice contain too much sugar and not enough of the important electrolytes lost during diarrhea and should only be taken alternately with a rehydration drink. In cases of severe dehydration, fluids may need to be replaced through an IV (intravenously).
When you feel well enough, begin eating mild, low-fat foods, such as bananas, rice, applesauce, or dry toast or crackers. This is called the BRAT diet. Avoid spicy foods, other fruits, alcohol, and coffee for 2 days and dairy products for 3 days after all symptoms have disappeared.
How can I prevent infection with noroviruses?
You can help prevent infection by doing the following:
Wash your hands before eating or preparing food. This is especially important if you have just changed any diapers or used the toilet.
Wash fruits and vegetables and steam oysters before eating them.
Clean and disinfect contaminated surfaces immediately after vomiting or having diarrhea by using a bleach-based household cleaner.
Immediately remove and wash soiled clothing or linens after vomiting or having diarrhea. Use hot water and soap.
Flush vomit and/or stool in the toilet, and make sure that the surrounding area is kept clean.
Do not prepare food if you have symptoms of food poisoning and for 3 days after you recover.

I'm concerned that she doesn't THINK it's Rotovirus. I have only heard of neurovirus as the flu..simply put. My son did have rotovirus and it is VERY contagious. If he/she is having major bowel issues, rotovirus cause very very stinky bowel-sulpher smelling actually and he/she can becaome very dehydrated very quickly. Keep the fluids going non stop until your kiddo is feeling better. My son despite lots of fluids was dehydrated in a matter of hours. We were at the Dr in the am with good numbers as far as ydration...in the ER by 5 pm severely dehydrated and on IV antibiotics. Keep a close eye, watch for paleness, lack of energy or interaction, If he or she turns away a drink don't waste time get to the ER or Dr immediately. Good Luck.

Your pediatrician probably stated "norovirus".
Norovirus' are a commonly occurring gastrointestinal virus which causes nausea/vomiting and diarrhea, occasionally with abdominal cramps. Norovirus is easily transmitted through contact with infected persons. This type of virus is usually self limiting, lasting 12-36 hours; however, there is a new norovirus which emerged in Europe last November and has been making its way across the US since January. The new strain may last as long as 4 days. One unique feature of this virus is the host does not become immune; consequently close family members may keep transmitting it back and forth. The best prevention is frequent and thorough hand washing--particularly for those who are caring for someone infected. Each time you clean up your child or the surfaces they have handled be sure to wash your hands and your child's hands.
The fluid loss from vomiting and diarrhea may lead to dehydration. Adults and children should make concerted efforts to take in plenty of fluids. For children you may want to contact your pediatrician about using a product like Pedia-lyte to replace electrolytes lost.
As in all health care related issues, your physician is your best resource for treatment modalities. If the vomiting/diarrhea persists for more than a couple of days, or dehydration becomes an issue be sure to see a doctor.

Wait, you slapped your youngster due to the fact that YOU had been indignant? There's a phrase for that: ABUSE. You NEVER hit a youngster out of anger. Ever. Children at that developmental level don't seem to be fully in manipulate in their feelings, so anticipating a infant to act "rationally" is not functional. They're going to have meltdowns and severe emotional reactions even to small matters oftentimes, and also you have got to receive that. They're additionally simply studying easy methods to use their phrases to explain what they want or wish. Her extraordinary conduct at the mobilephone used to be ordinarily extra involving her lacking her father than whether or not she used to be hungry or now not. Maybe in her brain, telling her father she used to be hungry used to be her manner of looking to provide him a motive to come back again dwelling. At her age, she's too younger to fully grasp that daddy is away in one more nation -- she handiest is aware of that he is now not dwelling. When he used to be dwelling, did they have a tendency to devour in combination? Did he ever aid with feeding her, or possibly giving her snacks or treats? Maybe her short of meals from him and now not accepting meals from you is her manner of claiming she misses her father's awareness. As a ways because the language mispronunciation is going, calm the heck down. Most babies have situation announcing a few phrases, however they be trained. You are not able to anticipate grammatical perfection from a two yr historic. She's be trained in time, simply preserve telling her the proper pronunciation and feature a few endurance.
