Norovirus, sometimes referred to as the winter vomiting bug, is the most common cause of gastroenteritis. Infection is characterized by diarrhoea, vomiting, and stomach pain. Blood is not usually present. Fever or headaches may also occur. This usually develops 12 to 48 hours after being exposed. Recovery typically occurs within 1 to 3 days. Complications may include dehydration.

The virus is usually spread by the faecal–oral route. This may be by contaminated food or water or person-to-person contact. It may also spread via contaminated surfaces or through the air. Risk factors include unsanitary food preparation and sharing close quarters. Diagnosis is generally based on symptoms. Confirmatory testing may be done for public health purposes

The most common symptoms are:

  1. Fever
  2. Headache
  3. Body aches
  4. Diarrhoea
  5. Vomiting
  6. Nausea
  7. Stomach pain

Preventions:

  1. Wash your hands often
  2. Rinse fruits and vegetables
  3. Cook shellfish thoroughly
  4. Stay home when sick and for two days after symptoms stop
  5. Avoid preparing food for others when sick and for two days after symptoms stop
  6. Immediately remove and wash clothes or linens that may be contaminated with vomit or poop.
  7. After someone vomits or has diarrhoea, always thoroughly clean and disinfect the entire area immediately.
