Norovirus: Symptoms and Treatment
Noroviruses, like other viruses, don't respond to antibiotics, which are designed to kill bacteria. No antiviral drug can treat noroviruses, but in healthy people the illness should go away on its own within a couple of days. Most people don't have any long-term problems from the virus.
To prevent dehydration, make sure to drink plenty of liquids, especially water and juices. Give children an oral rehydration solution (such as Pedialyte) to replace lost fluids and electrolytes. Avoid sugary drinks, which can make diarrhea worse, as well as alcohol and caffeinated beverages, which can dehydrate you further.
Symptoms of dehydration include dizziness when standing, dry mouth, and a decrease in urination. If severe dehydration develops, contact your doctor. Severe dehydration is sometimes treated with intravenous (IV) fluids.
How to Prevent Norovirus Infection
Good hygiene is the key to preventing an infection with norovirus, especially when you are in close surroundings with a lot of other people.
- Wash your hands often with soap and water for at least 15 seconds, or use an alcohol-based hand sanitizer, especially after going to the bathroom or changing a baby's diaper, and before you prepare or eat food.
- Carefully dispose of any contaminated items (such as dirty diapers).
- Wash raw fruits and vegetables thoroughly. Cook oysters and other shellfish before eating them.
- Clean and disinfect surfaces with a mixture of detergent and chlorine bleach after someone is sick.
- If you have norovirus, don't prepare food for at least two to three days after you feel better. Try not to eat food that has been prepared by someone else who is sick.
