Norovirus Gastroenteritis
Symptoms and Signs of Norovirus Gastroenteritis
Norovirus typically causes acute onset of vomiting, abdominal cramps, and diarrhea, with symptoms usually lasting 1 to 3 days. In children, vomiting is more prominent than diarrhea, whereas in adults, diarrhea usually predominates. Fluid losses vary from mild to severe Dehydration in Children . Patients may also have fever, headache, and myalgias. A positive test result for norovirus in a patient with atypical symptoms, such as bloody diarrhea, or in a patient testing positive for another pathogen suggests that norovirus is not the cause of the gastroenteritis.
