Introduction:

Norovirus is one of the main infectious agents causing acute diarrheal disease worldwide. The usual clinical manifestations for this agent are characterized by vomiting and watery diarrhea, however, in recent years, new variants or subtypes of norovirus have been reported in the literature, in which different clinical presentations have been described, as well as complications both intestinal and extra-intestinal.

Case report:

This work describes the case of an infant who began with vomiting of gastro-alimentary content and “coffee ground material”, which evolved into oral intolerance and dehydration, and who required intravenous hydration, as well as hospital surveillance. A gastrointestinal molecular panel was performed that reported norovirus.

Conclusions:

Norovirus is a frequent cause of infectious gastroenteritis and is important given the complications it presents in the digestive tract, including bleeding. At present, molecular panels facilitate the early identification of this virus and, in this way, help to treat complications, since they increase the morbidity of this pathogen.
