Nausea, Vomiting, and Diarrhea Are Common in Community-Acquired Acute Viral Respiratory Illness.

In this community-surveillance study of ARI, GI symptoms were common and associated with illness severity and respiratory pathogen detection. GI symptoms did not track with known GI tropism, suggesting GI symptoms may be nonspecific rather than pathogen-mediated. Patients presenting with GI and respiratory symptoms should have respiratory virus testing, even if the respiratory symptom is not the primary concern.
