==Overview==
==Overview==
The incubation period for norovirus-associated gastroenteritis in humans is usually between 24 and 48 hours (median in outbreaks 33 to 36 hours), but cases can occur within 12 hours of exposure. Norovirus infection usually presents as acute-onset [[vomiting]], watery non-bloody [[diarrhea]] with [[abdominal cramps]], and [[nausea]]. Low-grade fever also occasionally occurs, and vomiting is more common in children. [[Dehydration]] is the most common complication, especially among the young and elderly, and may require medical attention. Symptoms usually last 24 to 60 hours. Recovery is usually complete and there is no evidence of any serious long-term sequelae. Studies with volunteers given stool filtrates have shown that asymptomatic infection may occur in as many as 30% of infections, although the role of asymptomatic infection in norovirus transmission is not well understood.
Symptoms of norovirus infection include [[malaise]], [[fever]], stabbing diffuse [[abdominal pain]], [[diarrhea]], [[vomiting]], and [[anorexia]]. Parents of infected children may often report easy [[irritability]] and [[oliguria]]/[[anuria]].

===Common Symptoms===
Common symptoms of [disease] include:


If you have norovirus illness, you can feel extremely ill and throw up or have diarrhea many times a day.
