To prevent dehydration, take frequent sips of a rehydration drink such as Pedialyte. Try to drink a cup of water or rehydration drink for each large, loose stool you have. Soda and fruit juices have too much sugar and not enough of the important electrolytes that are lost during diarrhea, and they should not be used to rehydrate. In cases of severe dehydration, fluids may need to be replaced through an IV intravenously. Try to stay with your normal diet as much as possible.
Eating your usual diet will help you to get enough nutrition. Doctors believe that eating a normal diet will also help you feel better faster. But try to avoid foods that are high in fat and sugar.
Also avoid spicy foods, alcohol, and coffee for 2 days after all symptoms have disappeared. If you had diarrhea caused by noroviruses, you should stay home for 2 to 3 days after your symptoms end before going back to work or school. This will help prevent spread of the virus. You can help prevent infection by doing the following:.

Only a few norovirus particles can make other people sick. You are most contagious. However, studies have shown that you can still spread norovirus for two weeks or more after you feel better.
Norovirus can easily contaminate food and water because it only takes a very small amount of virus particles to make you sick. Food and water can get contaminated with norovirus in many ways, including when:. Norovirus is the leading cause of illness and outbreaks from contaminated food in the United States. Most of these outbreaks occur in food service settings like restaurants.
Infected food workers are frequently the source of outbreaks, often by touching ready-to-eat foods, such as raw fruits and vegetables, with their bare hands before serving them. Host cells have their own RNA molecules, which provide the instructions that cellular machines called ribosomes need to make proteins.
However, it remained unclear which host proteins were important for this key stage of the norovirus life cycle. Hosmillo, Lu, McAllaster et al.
Any proteins identified in these experiments would be fundamental for the norovirus life cycle, making them potential drug targets for future treatments. Noroviruses are highly contagious and are shed in the feces of infected humans and animals. You can get norovirus by:. Noroviruses are difficult to kill off because they can withstand hot and cold temperatures and most disinfectants. For most people, norovirus infection usually clears up within a few days and isn't life-threatening.
But in some people — especially children, older adults and people with compromised immune systems — norovirus infection can cause dehydration. Norovirus infection can cause severe dehydration, malnutrition and even death, especially in people who are older or immunocompromised, or in women who are pregnant. Children who are dehydrated might cry with few or no tears. They might be unusually sleepy or fussy. Norovirus infection is highly contagious, and anyone can become infected more than once.
