Viruses that cause acute gastroenteritis in people. Explore its illustrative 3D model, human context, and sources.
Human noroviruses cause acute gastroenteritis, with vomiting and diarrhea. This profile covers a clinical group rather than one viral species. Norovirus illness is distinct from influenza, despite the nickname ‘stomach flu’.
Fluid loss can become serious, especially in young children, older adults, and people with other illnesses. This tag describes a complication, not an individual risk score.
Original illustrative model of the Norwalk-virus capsid: a non-enveloped, approximately icosahedral VP1 shell with raised dimer domains around an RNA genome. The paired protrusion layout is symmetric but not fitted to a microscopy map. Other human norovirus genotypes vary. Independent scientific review remains pending.
