Norovirus infection is highly contagious. Follow these suggestions to help prevent norovirus infection from spreading:
- Wash your hands. Thorough hand-washing, especially after using the toilet or changing a diaper, can reduce the risk of transmission.
- Avoid contaminated food and water. Don't eat shellfish that may have come from contaminated waters. Throw out any food that may have been prepared by someone who was sick.
- Disinfect virus-contaminated areas. Use a chlorine bleach solution. Where possible, allow bleach to stay on surfaces longer than 10 minutes.
- Stay home from work. This is especially important if you work in a food-handling job. You may be contagious as long as three days after your symptoms end.
