[The Most Common Acute Gastrointestinal Infections].

Acute gastrointestinal infections and diarrhea with vomiting as its main presentation are a frequently encountered entity in an outpatient setting. Due to a mostly self-limiting disease course a diagnostic work-up is often futile. Viral infections caused by Noro- or Rotavirus are most frequent, while bacterial infections are second line due to high hygienic standards in developed countries. In an inpatient setting and after a precedent antibiotic treatment one should think of clostridium difficile. Traveler’s diarrhea represents a special case, with most of the cases caused by enterovirulent E. coli. In this mini review we describe the most important pathogens in detail.
