Can norovirus infections be prevented?

Yes. You can decrease your chance of coming in contact with noroviruses by following these preventive steps:

  • Frequently wash your hands, especially after toilet visits and changing diapers and before eating or preparing food
  • Carefully wash fruits and vegetables, and steam oysters before eating them
  • Thoroughly clean and disinfect contaminated surfaces immediately after an episode of illness by using a bleach-based household cleaner
  • Immediately remove and wash clothing or linens that may be contaminated with virus after an episode of illness (use hot water and soap)
  • Flush or discard any vomitus and/or stool in the toilet and make sure that the surrounding area is kept clean

Persons who are infected with norovirus should not prepare food while they have symptoms and for 3 days after they recover from their illness. Food that may have been contaminated by an ill person should be disposed of properly.
