Norovirus
Type of viruses that cause gastroenteritis
Medical condition
Norovirus, also known as Norwalk virus and sometimes referred to as the winter vomiting disease, is the most common cause of gastroenteritis.[1][6] Infection is characterized by non-bloody diarrhea, vomiting, and stomach pain.[2][3] Fever or headaches may also occur.[2] Symptoms usually develop 12 to 48 hours after being exposed, and recovery typically occurs within one to three days.[2] Complications are uncommon, but may include dehydration, especially in the young, the old, and those with other health problems.[2]
The virus is usually spread by the fecal–oral route.[3] This may be through contaminated food or water or person-to-person contact.[3] It may also spread via contaminated surfaces or through air from the vomit of an infected person.[3] Risk factors include unsanitary food preparation and sharing close quarters.[3] Diagnosis is generally based on symptoms.[3] Confirmatory testing is not usually available but may be performed by public health agencies during outbreaks.
