Preventive StepsHandwashing

All persons can decrease their chance of coming in contact with noroviruses by following these preventive steps:

  • Frequently wash your hands, especially after toileting or 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 diarrhea or vomiting by using a bleach-based household cleaner. If using liquid household bleach prepared daily, one part bleach to nine parts water (1:10 dilution) is recommended.
  • Man Holding His StomachImmediately remove and wash clothing or linens that may be contaminated with feces or vomit (use hot water and soap).
  • Flush or discard any vomit and/or stool in the toilet and make sure that the surrounding area is kept clean.
  • Persons who are infected with norovirus should refrain from food preparation while they have symptoms and for three days after they recover from their illness.

Outbreaks of norovirus in long-term care facilities are not uncommon and are frequently transmitted from person to person (including residents, staff, visitors and volunteers). Strict compliance with good hygiene practices is important to prevent the spread of norovirus in this population.
