About Norovirus

Norovirus is a viral infection spread through direct contact with someone infected with norovirus, eating food or drinking liquid contaminated with norovirus, or touching objects or surfaces contaminated with norovirus. Shellfish can be contaminated with norovirus if they are grown in contaminated water. 

Symptoms of Norovirus Infection

Symptoms typically appear 12 to 48 hours after exposure and can include: 

  • Vomiting
  • Watery diarrhea 
  • Abdominal cramps
  • Muscle aches
  • Headache
  • Fever
  • Chills

Most people feel better in 1 to 2 days but they can spread infection to others while they are sick and after their symptoms resolve. 

Prevention

  • Wash hands with soap and water after going to the bathroom, changing diapers, and before eating or preparing food.
  • Cook shellfish thoroughly and wash fruits and vegetables.
  • If you are sick with norovirus-like symptoms, stay home from work and do not cook food for others while you have symptoms and for at least 3 days after you recover. 
  • Clean and disinfect contaminated surfaces and wash laundry in hot water (see Resources below for detailed cleaning instructions).
