Noroviruses are the most common cause of gastroenteritis (stomach bugs) in England and Wales.

It is easily transmitted from one person to another by contact with an infected person; by consuming contaminated food or water or by contact with contaminated surfaces or objects.
What are the symptoms?
Sudden onset of nausea followed by projectile vomiting and watery diarrhoea, sometimes accompanied by a raised temperature, headaches and aching limbs. Symptoms start 12 to 48 hours after infection and last for 12 to 60 hours. A full recovery is usually made within 1-2 days, however, the very young or elderly may become dehydrated and require hospital treatment.

Good hygiene is most important - this includes thorough hand washing before and after contact. Avoid food preparation until 48 hours after the symptoms have subsided.
What can be done to prevent infection?
