Norwalk Virus

Norwalk virus is a common cause of vomiting and diarrhea each winter and has often been referred to as "stomach flu" or "Winter Vomiting Disease". Norwalk virus infections have been linked to outbreaks of vomiting and/or diarrhea in institutions such as child-care centres and long-term care facilities as well as on cruise ships and in camps, schools and households.

Noroviruses only infect humans. Outbreak sources are usually contaminated food and/or water.

  • A Norwalk virus infection results in illness 24 to 48 hours after exposure, and symptoms last from 12 to 48 hours. Illness is characterized by the abrupt onset of vomiting and/or non-bloody diarrhea; abdominal cramps are common.
  • Unlike rotaviruses, Norwalk virus infection is more frequent in older children and adults than in infants and toddlers.
  • There is currently no vaccine available for prevention of Norwalk virus. Since Norwalk virus is a virus, antibiotics are ineffective against it. [Mount Sinai/U of T]
