Norovirus Infection Symptoms and SignsThe symptoms and signs of norovirus infection usually occur within 12-48 hours of contact (incubation period) with the virus and often are first noticed within a cluster of people in a group (for example, military or school dorms, cruise ships, and nursing homes). Groups of people (although occasionally individuals) rapidly develop nausea, vomiting, diarrhea, and abdominal discomfort or cramping. Some people may develop low-grade fever (less than 101 F), headache, weakness, muscle aches, and loss of taste. The diarrhea may be frequent (many watery stools in 12-24 hours); for children, the elderly, or immunocompromised patients, this symptom can lead to dehydration (body water loss). The norovirus infection is usually self-limiting and resolves in about one to three days, but people with severe dehydration can develop complications (for example, electrolyte imbalances, coma, or infrequently, death).
